Deakin eSolutions Page 11 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 3 Purchasing requirements 3.1 Standard manufacturer and model range Deakin has standardised on H.323 standards compliant Cisco® (previously Tandberg®) equipment as specified in this document. No other brand or models or configuration options of videoconferencing equipment shall be deployed other than those specified. Any company undertaking videoconferencing works for Deakin must be an accredited Cisco® / Tandberg® Platinum Partner. Cisco® and Tandberg® have merged their product lines. Significant interoperability issues still exist with the non-standard Cisco® Telepresence Interoperability Protocol (TIP) products, and prior approval must be sought from DeS AV and Networks Unit Leader for any Cisco® TIP videoconferencing products. Tandberg® MXP series units were removed from the Deakin standards at the version 3.0 release. No further MXP series units shall be purchased without prior approval from DeS AV and Networks Unit Leader. They are superseded by the EX- and C-series units specified herein. 3.2 Maintenance contract Three years’ full maintenance support with the DeS selected vendor partner must be purchased at the time the unit is purchased. Special discounted bundle pricing negotiated for supply to Deakin only applies when the correct bundle of options, as set out in section 3.3, is selected, including 3 years full maintenance support. A unit will not be installed or supported by DeS if it is not under an initial 3 year maintenance contract. Please contact the DeS AV and Networks Unit Leader for more information before purchasing. Maintenance contracts must provide at least the following:  Local spares holding of all standard types (including previous standard types, i.e. 1700MXP, Edge95MXP, 6000MXP, PHD720p) and all central videocommunications infrastructure elements  Hours of coverage and responsiveness – including for spares provision: equal to or better than: 4 hours response; 9.00am to 5.00pm, Monday-Friday  Supplier knowledge of ISDN, UC  Support for test calls as required  Access to Cisco TAC and fault/bug database  Geographical coverage: to cover Deakin’s Victoria-wide footprint 3.3 Standard options All videoconference units shall be purchased with the following options configured. Special discounted bundle pricing negotiated for supply to Deakin only applies when the correct bundle of options as set out below is selected, including 3 years full maintenance support.  NPP = YES (refer section 6.5.1)  DD = YES (refer section 6.5.2)  PR = YES (refer section 6.5.3)  MS = NO (refer section 6.5.5)  12X camera = YES (refer section 6.9)  3 years maintenance included at time of purchase (refer section 3.2) Deakin eSolutions Page 12 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 4 Functional requirements 4.1 ‘Telepresence’-grade solutions ‘Immersive telepresence’-grade solutions are encouraged. The Deakin Standards recognize that the key attributes of immersive telepresence-grade videoconference facilities are:  Tightly framed life-size images with good eye-contact, i.e.: o 2-shot head and shoulders framing (or at most 3-shots on adequately sized widescreen displays) o wide-format tables so that everyone sits at the same correct distances, and no-one sits a long way away (cf non-preferred long-narrow format tables)  delivering unobstructed sight lines throughout o dual displays so that people are always shown full-size, even when content presentations are shown o images at close to eye-level and cameras for best eye-contact, this means:  lower edge of image at between 0.7 ~ 0.9 m AFFL (depending on image size), i.e. approx. in line with table top  camera lens at between 1/2 and 2/3 of image height AND between 1.2 ~ 1.5 m AFFL  Room acoustic treatment and audio systems to deliver quality sound  Room lighting, colours, interior decoration treatment and video systems to deliver uniform, standardized, high quality images  Ease of use intuitive, simple, user interfaces, including simple dialling  Seamless global reach ITU Standards dual stream (dual display format) compliant systems (the value of a telecommunications environment grows with the square of the number of reachable parties – Metcalfe’s Law). i.e. ‘Telepresence’ is a package that delivers a standards-compliant ‘life-like’ experience like being in the same room. Deakin eSolutions Page 13 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 4.1.1 Implementation For personal offices (AV02) this means use of EX90 up to a maximum of 3 participants only, seated within the maximum distances and angles as set out in section 5.2.1 below. For personal videoconference solutions (Jabber) this means use by a single person only and use of narrower field-of-view high quality cameras (Cisco PHD-USB camera). For meeting rooms (AV04) this means wide-format tables (arc, V, trapezoidal, oval, half oval), with camera presets configured for each pair of seats (2-shots). Illustrative case study: A typical 6 m x 4 m meeting room (F-ad6.202) was originally configured as a 9 seat long rectangular style meeting room as shown in figure (a) below. Reconfigured for telepresence-grade use, a wide arc (or wide V) table can accommodate 6 to 8 seats (figure b) while a wide rectangular table can accommodate 8 to 10 (figures c and d). (A) LONG RECTANGLE (B) WIDE ARC/V (C) WIDE RECTANGLE (D) WIDEST RECTANGLE Configured for a long rectangular table it suffers from all the usual limitations of that format (figure (A)):  Awkward compromise between single and dual displays, neither satisfactory: o With single display:  severe limitation resulting from inability to simultaneously view presentation content and the far-end audience;  the 2H-6H viewing distance rule (section 11.9) means that a very large display size is required, resulting in one or more of the following undesirable consequences:  camera displaced too high above the display, or to underneath the display both of which positions are entirely unacceptable (as per section 11.8) and hence non-conformant with the Deakin Standards;  high cost – LCD panel cost grows very rapidly (~exponentially) with size;  6H rule not achieved – people in the prime (chairperson’s) seating area at the head-end (rear) of the table cannot see graphic details (spreadsheets, diagrams, etc…) clearly. Deakin eSolutions Page 14 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards o With dual displays, although not suffering the camera angle problem of the single display, still suffers from significant viewing angle and viewing distance problems:  limited width of the end-wall limits screen size, meaning that 6H rule difficult or impossible to achieve, leading to the use of inadequately sized screens and hence people in the prime (chairperson’s) seating area at the head-end (rear) of the table cannot see graphic details (spreadsheets, diagrams, etc…) clearly;  a wrongly placed door (such as depicted in figure a) can exacerbate the problem further (in the above case ruling out the 2nd display entirely – the displays must be centred with the alignment of the table);  display width exceeds table width – meaning that most people need to look above, through or even behind other people’s heads to view the displayed images.  Which all results in, for either single or dual displays: o significant waste space at the front and/or rear of the room, and hence excessive building cost due to unutilized space – the table in figure a cannot be extended to the full size that the room can comfortably accommodate (cf figure d):  6H rule, coupled with limited practical display size, wastes space at the rear of the room;  2H rule, coupled with the large display size needed to attempt to reach the rear, wastes space at the front of the room; o very poor viewing angles with most people needing to:  turn their heads ~90 from their seating direction to view the displays, hence non-conformant with viewing angle requirements (refer ICT Resource 2.7.2 Sight Lines);  facing ~180 away from the chairperson when viewing the displays;  facing ~180 away from the camera when addressing the chairperson; and hence:  not possible to simultaneously view/face both the chairperson and the remote participants, and worse still:  facing away from the microphones when addressing the chairperson. Configured in telepresence-grade wide-format the following benefits result (figures (B)~(D)):  Excellent viewing angles: participants can face the chairperson, other local participants, remote participants, displays, camera – all with minimal head movements.  No-one completely turns their backs on anyone else when viewing the far-end or presentation.  Viewing angle to display (from seating direction) typically well under 45 cf around 90 or greater for long rectangular format.  All participants automatically always face approximately towards the microphones.  Inherent accommodation for the important second display – and hence the important ability to simultaneously view presentation content and the far-end participants in full size.  Easy accommodation for correctly sized displays.  All viewing angle and distance rules easily achieved.  Optimum camera height, and hence most life-like views and best eye-contact angles, always achieved. Deakin eSolutions Page 15 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards  All participants at closely uniform distances from the displays.  Hence very easy to achieve optimum 3H-4H viewing distances for all participants and room layouts.  Ensuring that far-end participants always life-size and  all participants consistently see fine detail in presented graphics, spreadsheets, diagrams, etc.  No obstructed sight lines.  No-one views anything above, through or behind anyone else.  Displays can always be fitted at the optimum height, i.e. so that bottom of the display is at tabletop height (~0.8 m AFFL) hence ensuring life-like positioning of far-end participants.  No waste space at the ends of the room. 4.2 Common requirements – all types of deployment All Deakin videoconference systems shall have the following attributes:  Conform to the standard models and standard configurations as specified in this document  Energy efficiency: Systems (including codecs, LCD and projector displays and other components) shall automatically power up/down (or leave/enter stand-by mode) at session-start and after session-end  Privacy: It is most important that LCD and projector displays automatically power up on receipt of a video (or voice)call to indicate session active  Remote management: All features to be able to be remotely monitored, controlled, configured and updated from a central management system, including the ability to remotely reboot and power-cycle individual components  H.323 and SIP compliant (hardware codecs)  H.323 or SIP compliant (software codecs)  Video codec: H.264 compliant  Wide-screen HD dual stream send and receive  Dual stream: H.239 compliant  Full HD 1920x1080p30 end-to-end (camera, codec, screen) on the primary ‘live’ video stream  Auto-focus motorized zoom full HD system-integral cameras  Full frame rate on both the ‘live’ and ‘content’ video streams simultaneously  6 Mbit/s transmission rate (‘live’ and ‘content’ streams combined)  Support for single and dual displays  Where dual screens are provisioned: o Screen 1 (the primary screen) is the Left screen (as viewed from the audience) and typically displays the ‘live’ video stream from the far-end Screen 1 supports up to at least Full-HD (1920x1080) o Screen 2 (the secondary screen) is the Right screen (as viewed from the audience) and typically displays the ‘content’ video stream from the local or far-end Deakin eSolutions Page 16 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards Screen 2 supports up to at least Full-HD (1920x1080) and preferably WUXGA (1920x1200)  Where multiple cameras are provisioned: o Camera 1 (the main camera) is the default camera following a session start-up and captures the primary audience area of the room  for meeting rooms (AV02, AV04) this means the primary seating area  for teaching spaces (AV06, AV08) this means the primary audience area o This means that in all cases Camera 1 faces from the ‘front’ towards the ‘rear’:  for meeting rooms (AV02, AV04): Camera 1 faces from the ‘front’ (presentation surface) towards the ‘rear’ (table area) of the room; and  for teaching spaces (AV06, AV08): Camera 1 faces from the ‘front’ (presentation surface) towards the ‘rear’ (audience area); while Camera 2 faces from the ‘rear’ of the audience towards the presentation desk.  Where whiteboard or SmartBoard (interactive whiteboard) functionality is required: o a whiteboard shall NOT be provided;

These can be operated in a number of user-selectable modes.  Far-ends to display the dual vision streams received.  The far-end/s (by default and on session start) send their Local Audience Cam (Cam 1) wide-shot as the ‘live’ stream and do not send a ‘content’ stream.  Far-end sent video camera selection, PTZ, and preset selection change can be triggered by pushto-talk audience microphones (optional feature in AV06-C e.g. for D@YD type applications)  A far-end can take over being Presenter by touching any vision selection button o These functions allow student participation/collaboration to contribute content from any end, simply by touching a suitable source button on the AMX touch-screen.  Dual feed iLecture capture appliance always captures what is displayed on the two main screens, which is in turn the same as what is sent to the far-end/s.  Single feed iLecture capture appliance can be switched at the UI to capture either of the local displays, but defaults to the ‘content’ video on the Right display (as viewed from the audience)  Graphical VU meter on UI displaying volume sent to far-end/s and to iLecture  UI buttons to allow lecturer to be able to pause and resume iLecture recording, as well as stop and start Deakin eSolutions Page 22 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards  Optional wide-screen Sympodium device o to be installed as a 4th display at the presenter’s desk, mounted at an adjustable angle but approximately horizontal, in front of the AMX touch panel  Gooseneck mic and wireless lapel mic are provided for the presenter  Fixed audience microphones are not required (neither ceiling arrays nor at audience seating positions); if required the following options are available: o minimum (i.e. for basic AV06-V and AV08): one handheld wireless microphone is normally provided, additional handheld wireless microphones can also be provided; o AV06-C teleteaching collaboration spaces (e.g. D@YD type spaces): fixed push-to-talk microphones at each student desk/positions; o AV04/6-H mtg/seminar spaces: suitable fixed table or ceiling microphone arrays; o smaller AV06-V spaces: optional suitable ceiling microphone arrays  All wireless mics to each be on their own dedicated radio channels – no exceptions!  No inbuilt multipoint – Deakin operates centralized MCU video network infrastructure 4.6.1 Summary of major AV06 / AV08 differences AV06 and AV08 are extremely similar – differences are as set out below: AV06 teaching space AV08 lecture theatre Room format Flat floor Tiered floor Videoconferencing (‘teleteaching’) optional YES (AV07 is identical to AV08 but without videoconferencing) Whiteboard optional – if present: off to the side and not involved in teleteaching NO Cameras 2 PTZ 2 PTZ plus optional 3 (if needed to adequately cover audience) Display type normally dual projectors optional dual LCDs (in smaller spaces) dual projectors Interactive presentation device optional SmartBoard (smaller spaces) or Sympodium (larger spaces) optional Sympodium Deakin eSolutions rd Page 23 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5 Technical specifications Detailed designs for each of the standard types are set out in the companion document ICT 2.6 Audiovisual and Videoconference Design Specifications. Technical requirements, standards and specifications are set out in this section and as below in the remainder of this document. 5.1 Common requirements (applies to all system/room types)  Each Detailed Design specifies the fully configured ‘base’ variant of the type o Optional components can be removed from the standard ‘base’ design but not added  ‘Out-of-the-box’ and ‘single-box’ solutions are strongly preferred o For example if the only driver for an integration solution is the number of microphones then a C20 shall be upgraded to a C60, or a C60 to a C90, as appropriate o Cost, complexity and unreliability all scale with the number of components in the solution LCD panels must be configured to wake when video sync is detected from the videoconference unit. LCD panels must be configured to go into Standby Mode when no video sync is detected from the videoconference unit. Projectors (which cannot automatically power on/off upon detection of video sync) must be controlled by an AMX controller. On receiving an incoming call, the AMX controller must automatically activate the projectors without local user action. Following session-end the AMX controller must automatically shut-down the projectors, including managing the projectors’ cool-down/restart cycle timers.    A single fully configured base design covers all of AV06, AV07 and AV08 o That standard AV06/07/08 base design also covers AV04/6-H hybrid applications (i.e. spaces that are used for both videoconference meetings and teaching)  Any system considered to require more than 4 microphones is now non-standard and as for any other non-standard configuration, permission must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. o Microphone design rules and positioning for different room types are set out in ICT Resource 2.7.3 Microphone Placement, but typically (depending on table shape), 1 microphone will be provided per each 4 to 6 seats. Deakin eSolutions Page 24 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5.2 Standard room types 5.2.1 AV02 – Executive Office  Must be an ‘Out-of-the-box’ all-in-one stand-alone videoconference Appliance for AV02. 5.2.1.1 Implementation Executive offices requiring videoconferencing are fitted with the Cisco/Tandberg EX90 desktop appliance, in one of three room configurations specified during the site audit: (A) On Executive Desk (in place of PC monitor)  To reduce clutter the EX90 can also be used as a PC monitor (B) On small meeting table (C) On credenza separate from (but nearby) small meeting table  To reduce clutter the EX90 has inbuilt microphone, however (particularly for configuration C) a single external MIC-20 can be attached  In all cases an uncluttered skirt area of minimum dimension 600Wx350D shall be available in front of the unit so as to not impede the inbuilt doc-cam function; this skirt area to be separate from the Touch-8 footprint (290Wx190D inc handset) which must also be accommodated in the immediate vicinity.  The Touch-8 is tethered to the EX90 via a short cable, and cannot be located remotely from the base unit.  The EX90 can be teamed with a 2nd 24” monitor to separately display ‘live’ plus ‘content’ video in dual-screen mode HP LA2405X 2 ND MONITOR ACCURATELY ALIGNED IN HEIGHT AND TILT TO THE RIGHT OF EX90: EX90 summary of features:  Inbuilt FullHD (1920x1080p30 dual stream) 6 Mbit/s codec  Inbuilt FullHD (1920x1080p30) motorized zoom camera Deakin eSolutions Page 25 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards     Inbuilt 61 cm (24”) FullHD/WUXGA (1920x1200) widescreen (16x10) LCD display Inbuilt stereo speakers Inbuilt microphone Inbuilt network switch so EX90 and downstream PC can share the one network port EX90 standard accessories:  Inbuilt document camera (main camera flips to provide doc-cam function)  Touch-8 touch screen UI complete with handset  External 150 W power supply EX90 optional accessories:  MIC-20 microphone (with inbuilt MUTE button and red/green mute indicator) with integrated 7.5 m cable  2nd 24” WUXGA (1920x1200) style matched monitor (as specified in the standard models section 6.6 below)  2nd monitor can optionally be a SmartBoard  Telephone-style system-integral Handset For configurations B and C a VGA cable (connected to the codec) shall be provided on the meeting room table, for connection to a laptop. The VGA cable to the laptop is to incorporate stereo audio coax, to be brought out from the VGA connector via 0.5 m tail terminated in stereo 3.5 mm mini-jack. For configuration C extending Ethernet to the meeting table is optional because the laptop will generally have wireless network access. Use of EX90 with small meeting tables is limited as follows: all participants must fit within the following envelope as measured perpendicularly from the centre of the EX90 screen:  Maximum distance: 2.0 m  Minimum distance: 0.6 m  Maximum angle: ±30 Where dual 24” screens do not provide adequate image area or where the above seating envelope is exceeded (e.g. larger configuration C rooms) a C20plus based meeting room system shall be provisioned instead (refer AV04 below). Deakin eSolutions Page 26 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5.2.2 AV04 – Videoconference Meeting Room  ‘Out-of-the-box’ and ‘single-box’ solutions are strongly preferred for AV04 o For example if the only driver for an integration solution is the number of microphones then a C20 shall be upgraded to a C60, or a C60 to a C90, as appropriate  Auto-switching between content sources is employed in AV04 to reduce the number of manual steps required of the end-user and to avoid the need for AMX controller or touch-screen in standard applications  Where an AMX controller is required, e.g. to control projectors in variant configurations (section 5.3) or blinds or lights, an AMX touch-screen is to be avoided. Instead: o the AMX controller shall deduce activity from signalling/activity it receives from attached equipment (e.g. codec) and/or from PIR detectors in the room; o a set of manual buttons will be provided within the locked AV rack for technician to manually control the AMX o Next-generation touch-screen/s will be specified in the 2012 AV/AMX Deakin standards documents for cases where touch screen is required o For AV04, touch screen is non-standard and as for any other non-standard configuration, permission must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis.  For AV04, all equipment should be located within the local room serviced, discretely within the room’s furniture, adequately and quietly cooled, and not in an exposed equipment rack o If there is no suitable accommodation within the room, larger integrated AV04-B systems may be installed in an AV rack nearby outside the room  The C20 is neither suitable nor intended for any type of integration or remote installation – the only item of ancillary AV equipment for the C20 in addition to its own standard accessories (MIC20 and PHD12X camera) shall be the 3 input autoswitcher (and of course the display devices, and PCs as appropriate)  Ceiling speaker arrays shall not be provided for standard AV04 rooms  Very large AV04 rooms: Any system considered to require more than 4 microphones is now non-standard and as for any other non-standard configuration, permission must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. o Microphone design rules and positioning for different room types are set out in ICT Resource 2.7.3 Microphone Placement, but typically (depending on table shape), 1 microphone will be provided per each 4 to 6 seats. 5.2.2.1 Implementation The Cisco/Tandberg C20plus is the default standard unit and is ideal for small-to-medium size videoconference meeting rooms in both single and dual screen configurations (AV04-xA). [ The single-screen restriction of the previous Edge95MXP (which the C20plus replaces) no longer applies.] In larger meeting rooms where additional inputs are required the C60 is substituted (AV04-xB), as set out below: Deakin eSolutions Page 27 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5.2.2.2 Standard configurations for AV04 AV04 – AA [1] C20plus C60 (alternate for AV04) single or dual LCD Displays single[2] or dual LCD Max Mics 2 (MIC-20) Max Mics 4 (XLR[3]) 1 (HDMI) Main camera 1 (HDMI) Main camera 2h (HDMI), 2d (DVI-I) n/c – not used 3d (DVI-I) Laptop cable Displays (default for AV04) AV04 – AB [2] inputs: 2 (DVI-I) Laptop cable Notes: [1] C20plus denotes C20 with 12X zoom PrecisionHD1080p camera. The base model C20 with downgraded 4X zoom camera MUST NOT be provisioned. [2] Dual display preferred; Single display is an allowable option for small rooms up to 6 seating positions; Single display is now non-standard for all rooms with more than 6 seats and as for any other non-standard configuration, permission must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. [3] XLR microphones of standard types as specified in section 6.8 below. LCD panels must be configured to go into Standby Mode when no video sync is detected from the videoconference unit. LCD panels must wake when video sync is detected from the videoconference unit. The meeting room table is to be provided with:  one (or two) VGA cables for connection to a laptop – one servicing the primary seating positions towards the rear of the room, the 2nd at a presentation position (if required) towards the front of the room;  a VoIP phone (preferably on credenza or otherwise on the meeting table itself); and  (preferably separately or otherwise via the VoIP phone) a wired Ethernet connection, loomed with the VGA cable/s to the laptop position/s. Each VGA cable is to incorporate stereo audio (shielded), to be brought out from the VGA connector via 0.5 m tail terminated in stereo 3.5 mm mini-jack. The 2nd VGA cable is to be provided in all hybrid AV04/6-H spaces, and in all larger standard AV04 spaces with greater than 10 seating positions. Where a System PC and/or 2nd laptop input is required, an autoswitcher is always added so that laptop cable and PC connect to the codec via the same one input. The autoswitcher will always switch video, audio and USB. Deakin eSolutions Page 28 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5.2.2.3 Variant configurations for AV04 While the standard configurations listed above will cater for most typical meeting room applications, the chosen platforms have much flexibility to support additional capabilities as set out below: C20plus[1] AV04-AA available for: [2] C60 AV04- xB available for: Displays single or dual (LCD panels only) Displays single[2] or dual (AV04-AB: LCD panels or AV04-BB: projectors) AMX [6] NO AMX [6] YES Max Mics 2 (MIC-20) Max Mics 4 (XLR[3]) Audio in [5] 2x RCA line-in Audio in [5] 2x RCA line-in 1 (HDMI) Main camera 1 (HDMI) inputs: 2h (HDMI) 2 (DVI-I) Laptop cable or Auto-sensing video switch (for System PC + 1x or 2x Laptop cable/s) Main camera [4] 2nd camera (e.g. to capture real whiteboard or presenter area) or 2d (DVI-I) [4] Doc-Cam (non-standard) 3d (DVI-I) Laptop cable or Auto-sensing video switch (for System PC + 1x or 2x Laptop cable/s) 3c (YC/C) n/c – not used Notes: [1], [2], [3]: As above – refer notes to table on preceding page. [4]: Inputs 2h and 2d are available as general-purpose but rarely used auxiliary inputs; Doc Cam is non-standard in AV04; to use both 2h and 2d in the same system requires AMX control (otherwise choice is only available by administrator configuration and only one is available via system-integral UI controller) [5], [6]: As below – refer following sections: Note [5]: Echo cancellation and mic mixing Always use the codec’s inbuilt echo-canceller and mic mixer, not echo cancellation or mic mixing in an external digital signal processor (DSP). The codec’s inbuilt automatic audio handling is clearly superior in meeting room applications than that of an external manually adjusted DSP. This also applies in hybrid AV04/6-H applications – the codec’s inbuilt echo-canceller and mic mixer is to be used, except where voice reinforcement is provisioned. However, voice reinforcement is non-standard for AV04/6-H hybrid and as for any other non-standard configuration, approval must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. Any system considered to require more than 4 microphones is now non-standard and shall be implemented using C90. As for any other non-standard configuration, approval must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. Deakin eSolutions Page 29 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards Note [6]: AMX control The use of an AMX in a meeting room is to be avoided where possible, the system integral remote controller being a more attractive choice. AMX is non-standard for AV04 and as for any other non-standard configuration, approval must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. Where needed, an autoswitching video switch shall be supplied to select between PC and laptop input/s. Manual control adds unnecessary complexity to the user function and is not provided. An AMX controller or touch panel is therefore not required for this function. The autoswitcher priority shall be: 1. Laptop at the primary sitting position (facing towards the screens) 2. 2nd laptop (if provisioned) at the presenter’s position (facing towards the local audience) 3. System PC LCD panels shall be configured to automatically go into Standby Mode when no video sync is detected from the videoconference unit, and to automatically wake when video sync is detected from the videoconference unit. Therefore an AMX is not required for LCD power-management. AMX controller is required to control projectors (which cannot automatically power on/off upon detection of video sync), and may also be required for other secondary functions such as blinds or lights, however an AMX touch-screen is still to be avoided – the AMX controller can sense required operation by combination of control signalling received from the codec and other attached devices, plus PIR inputs. On receiving an incoming call, or other local activation of the codec (e.g. for local display of PC content), the AMX controller must automatically activate the projectors. Following session end the AMX controller must automatically shut-down the projectors. A special case is hybrid spaces that are used for both meetings and teaching – all teaching spaces require an AMX touch panel. Hence such hybrid spaces are based on the AV06 configuration (below). SmartBoard Single screen AV04 systems may optionally use a SmartBoard as the (sole) display device (in conjunction with Cisco Sync device). For dual screen AV04 systems, a SmartBoard may be used, as the Right display; with matching UST projector as the Left display – both projectors shall be of the same type and image size. The SmartBoard shall connect to the system PC (via USB). Deakin eSolutions Page 30 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5.2.3 AV06-V – Teaching Space Videoconferencing is optional in an AV06 teaching space.  A single fully configured base design covers all of AV06, AV07 and AV08, including hybrid (AV04/6-H) applications  Full integration solutions, complete with AMX controller and AMX touch-screen, are mandatory for AV06, AV07 and AV08, including hybrid (AV04/6-H) applications  Dual display is mandatory for all AV06, AV07 and AV08, including variant (AV04/6-H and AV06-C) applications 5.2.3.1 Implementation Where a teaching space requires videoconferencing, a Cisco/Tandberg C60 (or C90) is provisioned. The codec is installed in the equipment rack along with the other system AV equipment – this may be within the presenter’s desk in the room, or remotely in an AV rack nearby but outside the room. The system is always controlled via AMX. Dual displays are always provisioned. For small classrooms this may be dual LCDs, but generally dual projectors will be provisioned. The presenter’s desk is provisioned with 3 displays: 2 vision monitors and 1 AMX touch screen. The vision feeds to the desk are independent from the vision to the main displays. Specific vision routing is programmed specific to the teleteaching application (refer section 4.6 for details). Two PHD1080p12X cameras are provisioned, one at the rear of the space pointing towards the presenter, and one at the centre of the front of the space facing towards the audience, located between the two displays. Document Camera, system PC and provision to connect a laptop are always provided. The VGA cable to the laptop is to incorporate stereo audio (shielded), to be brought out from the VGA connector via 0.5 m tail terminated in stereo 3.5 mm mini-jack. Instead of a whiteboard, a SmartBoard shall be provided, on the right display (if a short presenter would be able to reach the top of the projected image) or otherwise a Sympodium shall be provided. Both projectors shall be of the same UST type and image size. The SmartBoard / Sympodium shall connect to the system PC (via USB). 5.2.4 AV08 – Lecture Theatre with videoconferencing Videoconferencing is optional in a lecture theatre. AV08 specifies the requirements of a lecture theatre with video conferencing.  A single fully configured base design covers all of AV06, AV07 and AV08  Full integration solutions, complete with AMX controller and AMX touch-screen, are mandatory for AV06, AV07 and AV08  Dual display is mandatory for AV06, AV07 and AV08 5.2.4.1 Implementation Where a lecture theatre requires videoconferencing, a Cisco/Tandberg C60 (or C90) is provisioned. The codec is installed in the equipment rack along with the other system AV equipment – this may be within the presenter’s desk in the room, or remotely in an AV rack nearby but outside the room. The system is always controlled via AMX. Dual displays are always provisioned. Suitable dual projectors shall be provisioned. The presenter’s desk is provisioned with 3 displays: 2 vision monitors and 1 AMX touch screen. The Deakin eSolutions Page 31 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards vision feeds to the desk are independent from the vision to the main displays. Specific vision routing is programmed specific to the teleteaching application (refer section 4.6 for details). At least two PHD1080p12X cameras are provisioned, one at the rear of the space pointing towards the presenter, and one at the centre of the front of the space facing towards the audience. Additional cameras are provisioned as appropriate. Document Camera, system PC and provision to connect a laptop are always provided. The VGA cable to the laptop is to incorporate stereo audio (shielded), to be brought out from the VGA connector via 0.5 m tail terminated in stereo 3.5 mm mini-jack. Instead of a whiteboard or a SmartBoard, where required, a Sympodium shall be provided. 5.3 Variant cases – teleteaching Summary of teleteaching room configuration options: AV04/6-H teleteaching mtg/seminar room AV06-V teleteaching classroom AV06-C collaboration space AV08 teleteaching lecture theatre Room format Flat floor Flat floor Flat floor Tiered floor Seating Fixed or Flexible Fixed or Flexible Fixed Fixed Table/s Optional meeting room style central table Optional individual student desks Multiple small-group collaboration tables (e.g. 2-person kidney/oval tables) Individual (integrated with lecture theatre seats) Presenter’s desk NO (optional lectern) YES YES YES Doc Cam optional YES YES YES Cameras 1 PTZ (front) (plus optional rear PTZ) 2 PTZ 2 PTZ 2 PTZ plus optional rd 3 (if needed to adequately cover audience) Audience participation Full mic coverage Wireless handheld mic only Push-to-talk mic on each table Wireless handheld mic only Audience camera coverage manual PTZ manual PTZ automatic camera follows active mic manual PTZ Display type normally dual LCDs optional dual projectors (in larger spaces) normally dual dual UST projectors projectors optional dual LCDs (in smaller spaces) dual projectors Interactive presentation device optional SmartBoard optional SmartBoard (smaller spaces) or Sympodium (larger spaces) optional Sympodium Deakin eSolutions Page 32 of 78 YES SmartBoard (smaller spaces) or Sympodium (larger spaces) Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 5.3.1 AV04/6-H – Hybrid videoconference meeting/seminar/teaching space Some videoconference meeting rooms may also be used for small-group tutorials, seminars or informal teaching. These are always flat-floored spaces. Technical design uses the AV06-V ‘base’ detailed design, using the C60/C90, but cut-back for the intended application. As such, the room shall be fitted with dual displays, system PC, an AMX controller and touch-screen. The vision flow settings shall default to those suitable for a normal AV04 ‘meeting’, however for larger hybrid AV04/6-H spaces a welcome screen may be provided to select between startup vision settings suitable for AV04 (‘meeting’) and AV06 (‘teaching’) sessions. However these options affect only the initial settings, and do not limit functionality during the session – the full AV04 and AV06 functionality is available during the session. A presenter station is optional (generally omitted), but as a minimum the 2nd Laptop connection point must be provided for a presenter near the front of the room. The AMX touch screen cable must be long enough to allow the touch screen to be used in primary meeting seats and in presenter seats near the front. The AMX menu layout shall be opposite to the standard AV06, i.e. in hybrid spaces: Left display choices are on the Left of the touch screen, and Right display choices are on the Right of the touch screen. The codec’s inbuilt echo canceller and mic mixer shall be used (as per AV04), except where ceiling microphones (flexible furniture space) or voice reinforcement is provisioned. However, voice reinforcement is non-standard for AV04/6-H and as for any other non-standard configuration, approval must be obtained from the DeS AV and Networks Unit Leader on a case-by-case basis. Where flexible furniture is required, suitable microphone arrangements must be approved by the DeS AV and Networks Unit Leader on a case-by-case basis, and according to the requirements of section 6.8 below. Alternatively, a standard dual display AV04 design can be successfully used ‘as is’ for low-end small-group hybrid meeting/seminar/teleteaching applications. 5.3.2 AV06-C – Teleteaching collaboration space (e.g. D@YD spaces) Same as basic AV06-V teleteaching classroom, except with the following additions:  SmartBoard or Sympodium (refer next section)  Push-to-talk microphone system on each student desk  Camera follows active mic automatic PTZ camera control system 5.3.3 SmartBoard A whiteboard is not recommended for any type of videoconference application, due to difficulty of capturing diagrams due to too much white-space and the highly reflective surface. Superior alternatives are Sympodium appliance or SmartBoard depending on room size. A SmartBoard is suitable as follows:  for personal offices (AV02), as the 2nd (‘content’) display;  for single display meeting rooms (AV04), in conjunction with the Cisco Sync device;  for dual display meeting rooms (AV04), as the Right (‘content’) display;  for smaller AV06 teleteaching classrooms where it can be mounted 700 mm AFFL, as the Right (‘content’) display.  SmartBoard is not suitable for larger teaching spaces or Lecture Theatres, where a Sympodium shall be used instead. Deakin eSolutions Page 33 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards Where a SmartBoard is provided, the following conditions shall apply:  The SmartBoard substitutes for the Right (‘content’) display in AV02 personal offices  The SmartBoard substitutes for the sole display in single display AV04 meeting rooms Where a SmartBoard is provided for dual display AV04 and AV06 spaces, the following conditions shall apply:  The SmartBoard is fitted as the Right ‘content’ display  This, by definition, means that the space must be fitted with dual displays, which must be matching UST projectors  The two projectors must match in Brightness, Size, Aspect Ratio (16x10 wide-screen) and Height above floor o The Right UST projects onto the SmartBoard while the Left UST projects directly onto the white wall, using the same ultra/short throw mount/lens so that the presenter is not within the projected beam when using the SmartBoard function  USB switching must mirror vision switching so that the SmartBoard is connected to the correct PC/laptop currently being displayed on the Right projector o This, by definition, means that USB extension must be provided to laptop positions Where a Sympodium is provided (AV06 and AV08), the following conditions shall apply:  The Sympodium is mounted on the presenters desk in front of the AMX touchpanel  USB switching must mirror vision switching so that the SmartBoard is connected to the correct PC/laptop currently being displayed on the Right projector o This, by definition, means that USB extension must be provided to laptop positions  The System PC/laptop shall still be able to be displayed on the Right, Left or both displays as per normal vision switching flows available on the AMX touchpanel Deakin eSolutions Page 34 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6 Standard Models A comprehensive list of standard components is provided in Appendix B. There are three distinct categories of videoconference unit: Type Deakin standard model Supersedes Desktop appliance EX90 1700MXP Component system (non-integrated) C20plus (default) or Edge95MXP C60/C90 (if required) 6000MXP C60 or 6000MXP Integrated system (AMX integration) C90 (if required) The EX60, SX20, MX200, C40 or other models are not to be provisioned under any circumstances. 6.1 Cisco/Tandberg EX90 The EX90 model (replaces the 1700MXP) is ideal for single person use or for small groups up to 3 people in a personal office environment. Many of the University's Senior Executive and senior staff are equipped with this model (or its predecessor). The EX90 allows presentations and other displays to be shared from a laptop or desktop PC/Mac, via the videoconference session, to the remote party/ies. To minimize clutter the EX90 has a high fidelity inbuilt microphone. For larger areas the EX90 can optionally also be fitted with a Tandberg MIC-20 external microphone. The MIC-20 has inbuilt Mute button with red/green mute status indicator light. The EX90 has an inbuilt full high definition camera. The camera can be flipped to provide an inbuilt document camera function. CISCO/TANDBERG EX90 Deakin eSolutions The EX90 has a built-in WUXGA (1920x1200) full HD 24” LCD display. To further eliminate clutter, the EX90 can double as a PC screen. Conversely a 2nd 24” monitor can optionally be added for dual screen viewing. Page 35 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.2 Cisco/Tandberg C20plus The C20plus is suitable for most meeting room environments. The C20plus allows presentations and other displays to be shared from a laptop or desktop PC/Mac, via the videoconference link, to the remote party. The C20plus does not come with a built-in display – the display/s are purchased separately. The C20plus can support single or dual screens. During the pre-ordering audit of a room, our staff will discuss the requirements of the room and recommend a screen size, as set out in section 8.6 below. Larger screens are more expensive. This model is usually mounted on a fixed stand, which is made to fit the screen/s. CISCO/TANDBERG C20 The C20plus can have up to two MIC-20 microphones without further integration equipment being required. The MIC-20 microphone comes complete with integrated 7.5 m cable and inbuilt MUTE button with red/green mute status indicator light. This model is supplied with a full high definition 12X zoom camera (the downgraded 4X camera is not to be provisioned). The C20plus cannot be integrated with an AMX controller. 6.3 Cisco/Tandberg C60 / C90 The C60 and C90** are high end videoconference units, designed for integration with other audio visual equipment, such as in a boardroom or large meeting room. Lecture theatres, classrooms and integrated room systems are equipped with this model (or its predecessor). The C60 / C90 do not come with a built-in display – the displays are purchased separately, or the output is projected on to an appropriate surface such as a blank white wall. CISCO/TANDBERG C60 CISCO/TANDBERG C90 Deakin eSolutions During the pre-ordering audit of a room that is to be fitted with videoconferencing, our staff will discuss the requirements of the room and recommend a screen size, as set out in section 8.6 below. Larger screens are more expensive. In common with the EX90 and C20plus these models are capable of running two separate screens simultaneously. The C60 has four microphone inputs (and the C90 has eight) each input having its own separate inbuilt echocanceller, as well as the ability to integrate well with other audiovisual equipment. During the pre-installation audit, our staff will recommend the number of microphones that should be installed. This model is supplied with a full high definition camera. A 2nd camera will be added for all teaching spaces. Additional cameras may be required for some large installations, such as lecture theatres. Page 36 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.4 Firmware Due to firmware compatibility issues that exist between videoconferencing infrastructure and endpoints, DeS sets a firmware baseline which is upgraded approximately every 6~12 months. All equipment being introduced into the videoconferencing environment will adhere to the baseline. Contact the DeS AV and Networks Unit Leader or delegate to determine the current approved endpoint and infrastructure firmware versions. 6.5 Configuration options All videoconference units shall be purchased with the following options configured. Special discounted bundle pricing negotiated for supply to Deakin only applies when the correct bundle of options as set out below is selected, including 3 years full maintenance support.  NPP = YES  DD = YES  PR = YES  MS = NO  12X camera = YES (refer section 6.9)  3 years maintenance included at time of purchase (refer section 3.2) 6.5.1 Natural Presenter Pack (NPP) NPP is no longer a separable option – all C/EX-series units come with NPP bundled by default. The Natural Presenter Pack (NPP) allows laptop/content presentations to be made via the videoconference codec. NPP is bundled with each videoconference codec deployed. A codec will not be deployed without the NPP. No exemptions will be granted for installation without the NPP. This is not negotiable. Illustration Description The Tandberg Natural Presenter Pack allows PC input to be shown at the same time as showing the presenter. 6.5.2 Dual Display (DD) option All Deakin C/EX-series units are provisioned with the Dual Display feature enabled. This is not negotiable. Special bundled discounts have been negotiated with the manufacturer incorporating this feature. These special discounts are not available without this option. Deakin eSolutions Page 37 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.5.3 Premium Resolution (PR) option All Deakin C/EX-series units are provisioned with the HD1080/WUXGA feature enabled. This is not negotiable. Special bundled discounts have been negotiated with the manufacturer incorporating this feature. These special discounts are not available without this option. 6.5.4 Bandwidth options There are no bandwidth options for the C/EX-series, all are supplied with the maximum bandwidth they are capable of, as set out in the table below. Each codec purchased is purchased with the maximum bandwidth it is capable of. Model Bandwidth EX90 6 Mbit/s C20plus 6 Mbit/s C60 / C90 6 Mbit/s 6.5.5 Multisite (MS) option Multisite is not part of the Deakin standard configuration. Instead Deakin uses centralized bridging to achieve this functionality (refer MCU section below for details). MCU services such as Virtual Meeting Points are used instead, negating the need for Multisite. If Multisite option is installed (e.g. as a result of option package bundling) it shall be disabled, for three important reasons:  Confusion: Adds unnecessary complexity and permutations to user information and training.  Accidental cascading: A very common user error is adding endpoint bridging to a centrally bridged session, leading to entirely unsatisfactory “MCU composite image inside MCU composite image” nesting. This is a common source of user complaint about inadequate multipoint image sizes/layout due the resulting very small MCU-within-MCU window nesting  Reduced picture quality: MS reduces bandwidth (and hence picture quality) available per participant by almost a factor of two: i.e. only 3.3 Mbit/s per participant cf 6 Mbit/s without MS. If requested in niche cases, e.g. private use executive office or to exploit inbuilt C-series dualscreen “immersive Telepresence” mode, suitability shall be assessed at the time of audit. As for all non-standard configurations, approval must be obtained from DeS AV and Networks Unit Leader on a case-by-case basis. Deakin eSolutions Page 38 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.6 Displays Only the following standard size displays shall be deployed. The size of display appropriate to the installation space will be determined during the audit phase, and as set out in the design rules in section 11.9.

Plasma screens shall not be used due to their power consumption. In dual-screen deployments:  Both displays shall ALWAYS be of the same type and size  The Right screen (as viewed from the audience) shall be the (2nd) ‘content’ display  The Left screen (as viewed from the audience) shall be the (primary) far-end ’live video’ display Deakin eSolutions Page 39 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.7 Speakers The speakers will be supplied in a colour that matches the monitor for uniformity of installation. For example, black matte monitor will have black matte speakers. For dual screen installations, one pair of speakers only will be deployed (i.e. not four speakers for two monitors). In rooms with separated Program Audio and Voice Reinforced Audio, the Far End audio shall be sent to the (Front-of-House) Program Audio speakers only, so as to achieve correct spacial alignment of the Far End audio with the Far End video displays. Specifically: AV02 Use inbuilt stereo EX90 speakers only AV04 (inc. hybrid AV04/6-H spaces) Single stereo FoH speaker pair (‘Program Audio’) only (attached to LCD panel/s or SmartBoard; or attached at presentation wall in case of projectors) No ceiling arrays; No separated ‘Voice Reinforced Audio’ system All audio via FoH speaker pair only Local mics to codec only – no local voice reinforcement In very large AV04 board rooms, ceiling array may be added (non-standard), however these will be run from the same FoH audio feed (no 2nd audio mix) AV06 / AV08 Separated ‘Program Audio’ (FoH) and ‘Voice Reinforced Audio’ (ceiling array) FoH: Stereo; Ceiling array: Stereo Local content sources (PC/laptop) to codec and to local ‘Program Audio’ (FoH) Local mics to codec and to local ‘Voice Reinforced Audio’ (ceiling array) Audio from codec to local ‘Program Audio’ (FoH) In very large AV08 lecture theatres, Program Audio may be added to the mix to the Reinforced Audio ceiling array (non-standard) Deakin eSolutions Page 40 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.8 Microphones The audit of the installation space will determine the type and number of microphones required. Omnidirectional microphones shall not be used. Microphones shall be selected from the following standard models: All microphones shall be fixed to the table in the correct orientations as designed by the room audit. The ‘backs’ of all directional microphones are to face towards the videoconference display screens, exact orientation as specified by the detailed room design, refer ICT Resource 2.7.3 Microphone Placement for details. Illustration For Description AV02, AV04 Cisco/Tandberg MIC-20 This microphone is the standard accessory for and is compatible only with the C20 and EX90 systems. One MIC-20 comes bundled with the C20, and a 2nd can be added for larger meeting rooms. The EX90 has an inbuilt microphone, and a single MIC-20 can be added as an optional accessory. The MIC-20 is an omnidirectional microphone, with an inbuilt MUTE button and red/green mute indicator, and integral 7.5 m cable with proprietary 4way 3.5mm jack. The cable cannot be extended and the microphone cannot be fitted to any other system. AV04 Audio Technica U851R Unipoint Cardioid Condenser Boundary Microphone This is the most common microphone in meeting rooms. As for all other microphones, the microphone is to be fixed to the table in its correct orientation, and the ‘back’ of the microphone is to face towards the videoconference display screens. AV04 Audio Technica ES947 Cardioid Condenser Boundary Microphone This model microphone will be used where a microphone is required to be fitted into a table for aesthetic reasons. Despite appearances, this microphone is a directional cardioid microphone: DESIGNATES ‘ FRONT’ OF MIC Installation must take careful note to orient this small dot correctly, i.e. away from the videoconference display screens Deakin eSolutions Page 41 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards AV06, AV08 Shure Gooseneck microphone MX-418 If the room audit specifies the use of a gooseneck microphone, this model will be deployed. Only used on presenter’s desks. Wireless handheld microphones and wireless lapel microphones are only to be provisioned in classrooms and lecture theatres (AV06/AV08) – refer ICT 2.2 AV Technical Design Standards for details. Wireless tabletop microphones are not to be provisioned. 6.8.1 Microphone placement Microphones shall be fixed into their correct positions (not user alterable), and face generally away from the FoH presentation area. Microphones shall be placed at least 0.5 m from side or rear table edges (preferably greater than 0.6 m). Microphones shall be provisioned at the rate of approximately 1 microphone per:  7 seats for typical rectangular table  4 seats for larger square or ‘U’-shaped table  small round/oval/square table (3 to 6 seats) Comprehensive microphone placement and design specification details are provided in the companion document ICT Resource 2.7.3 Microphone Placement. 6.8.2 Reconfigurable spaces Fixed configuration rooms (i.e. fixed furniture layout) are strongly recommended so that quality for-purpose microphone arrangements can be provisioned. Flexible use rooms (movable furniture) suffer from degraded audio because of the difficulty of adequately provisioning microphone coverage. Wireless microphones are not to be used to address this application. Advanced ceiling microphone arrays suitable for this application will soon be specified at the next update to this Standard, refer to ICT Resource 2.0.1 Addenda and Updates. Suitable microphone arrays must be designed specific to the space strictly on a case-by-case basis. Contact DeS AV and Networks Unit Leader for details. Reconfigurable spaces must have suitable acoustic treatment so as to exceed the requirements set out in section 11.6. Deakin eSolutions Page 42 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.9 Cameras Only Cisco/Tandberg Precision HD (PHD) cameras shall be used. Note: the C-series video conference units shall only be purchased with PrecisionHD 1080p 12X cameras. In particular: the 4X camera (available as a low-end option for the C20) shall not be purchased. The number of cameras to be installed in a videoconference space will be determined at audit, however the below table serves as a guide: Type of space Standard camera arrangement Personal office EX90 with inbuilt camera (AV02) The EX90 has a single camera with motorized zoom and auto-focus. The zoom should be set to have the main participants around the table or desk in clear view. The camera can be manually flipped to function as a document camera. Meeting room C20+ with Precision HD 1080px 12X camera (AV04) The C20+ is supplied with one Precision HD 1080p 12X camera. The C20+ shall only be used with one Precision HD camera. If additional cameras are required, the C60 codec will be used. Large meeting room C60 ** with multiple Precision HD 1080p 12X cameras (AV04) Large meeting rooms will have sufficient cameras such that all participants are covered by a camera. Teaching space or Lecture Theatre C60 with multiple Precision HD 1080p 12X cameras (AV06-V/C, AV08 inc. hybrid AV04/6-H spaces) Teaching spaces will have at least two cameras. One will be positioned at the rear of the venue directed toward the presenter. The second camera will be mounted in the centre front wall (between dual projected images) directed toward the audience. ** Note: C90 if required by number of inputs (refer text) Deakin eSolutions Page 43 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.9.1 Camera presets Camera presets depend on the layout and purpose of the room. The following table is to be used when setting camera presets. Each preset records Pan, Tilt, Zoom and Focus settings along with Mic Mute status at the time of programming. Therefore presets are always to be programmed with Mic Mute OFF. Camera presets must be set as part of the in-venue system commissioning, as set out in ICT Resource 2.7.4 Camera Presets. Note: Rooms with AMX® control shall recall the presets saved using the Cisco® endpoint camera presets. This is to allow pan/tilt/zoom/focus adjustments to the presets, without the requirement for AMX® code changes. Type of space Standard camera arrangement Personal office No presets (EX90 has inbuilt camera without presets) (AV02) Meeting room (single/dual screen) (AV04) (1 camera assumed) Preset 0 – Same as Preset 1 [where available] Preset 1 – Default shot following startup from standby: Central Tight shot (covers 2-3 people in primary seating area) Preset 2 – Central Mid shot (covers 4-6 people in main seating area) Preset 3 – Left Table/Room Preset 4 – Right Table/Room Preset 5 – Wide view to cover all participants NOTE: Meeting rooms with two cameras will default to Camera 1 and Camera 1 shall be the camera that provides best coverage of the primary seating area. Teaching space / Lecture Theatre (AV06 / AV08) (2 cameras assumed) Preset 0 – Same as Preset 1 [where available] Preset 1 – Default shot following startup from standby: CAM 1 – Wide shot of audience Preset 2 – CAM 2 – Mid shot of lecturer, covers the lecturer desk Preset 3 – CAM 1 – Audience Left Preset 4 – CAM 1 – Audience Right Preset 5 – CAM 1 – Wide shot of audience (camera is tilted so that projector lenses also in shot for DeS troubleshooting purposes) Preset 6 – CAM 2 – Wide shot of lecturer, covers the projected images too (for far-end monitoring/checking) D@YD type spaces with push-to-talk student microphones shall in addition have one Audience Cam (CAM 1) preset for each push-totalk station. Pressing the push-to-talk button will activate the associated preset. NOTE: Teaching Spaces and Lecture theatres will default to Camera 1 Preset 1.

Where a cable run is over 20 metres HDMI will be used over CAT6a, using approved transceivers as specified in ICT Volume 2.2. The Cisco/Tandberg Precision HD camera shall be connected to the codec as per Cisco/Tandberg specifications, including daisy-chained control cable. Additional cameras (2nd, 3rd, nth camera) require Ethernet network connection to allow for remote software upgrades. Camera must be on the same subnet as the codec. [Tandberg TVS shall not be used – not required with C series.] Illustration Description The TANDBERG Precision HD 1080p 12X Camera captures images at a resolution of up to 1920 x 1080 @ 60fps/ frames per second (HDMI and SDI outputs) with 12X zoom. (Use with C-series). The 4X zoom model is not to be provisioned Illustration Description The Tandberg Precision HD 720p 7X Camera captures images at a resolution of 1280 x 720 pixels at 30 frames per second. (Use with Edge 95 and 6000 MXP series ONLY). PHD 1080p 12X and PHD 720p 7X cameras shall not be used together in the same venue / system. 6.9.3 Use of PC/laptop and IP video cameras PC/laptop/tablet/smartphone cameras are used by desktop/mobile videoconference software applications, but are not a component of a hardware-based videoconference system. DeS is evaluating Cisco Jabber as candidate for standardizing Desktop desktop/mobile videoconferencing. IP video cameras (which are generally used for surveillance applications) are not a component of a standard videoconference system. An IP camera may be mounted at the rear of a room for DeS remote troubleshooting purposes in conjunction with RMS. Deakin eSolutions Page 45 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 6.10 Remote control The following model remote controls are the only allowable remote controls to be used with videoconferencing equipment where the codec is not controlled via AMX touch-screen:   for MXP-series: Tandberg TRC-4 for C-Series: Cisco/Tandberg Touch-8 The Cisco Touch-8 system integral touch panel shall be provided as the standard user interface device for C-series systems that do not have AMX touch controllers in:  all fixed-furniture meeting rooms; and  where practical in flexible furniture spaces, in which case the Touch-8 should preferably be placed on a credenza or other convenient fixed furniture. In all cases, the entirety of the proprietary 7.5 m cable must be freely available so users can move the Touch-8 panel to suitable location. Cisco/Tandberg Touch-8 touch panel for C-series codecs Note that the proprietary 7.5 m cable has non-standard connectors to reflect that it utilizes non-standard PoE (entirely different voltage) and must be connected directly to the non-standard PoE injector provided with the Touch-8. The Touch-8 must not be powered or connected directly to a standard Ethernet port. The PoE injector must be installed on the underside of the meeting room table or in the credenza. The Ethernet cable upstream from the PoE injector may be connected:  to a Deakin network Ethernet port (for C20, C60 or C90); or  directly to the codec’s 2nd Ethernet port (for C60 and C90 only) The Touch-8 (variant with handset) used in conjunction with all EX90 appliances must be directly connected to the EX90, in which case no PoE injector is involved.

Deakin eSolutions Page 48 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 8 Network and supported protocols A dedicated Ethernet network point shall be provisioned for the use of the videoconference unit. A videoconference unit can be plugged into any Ethernet walloutlet, which no longer needs to be specially configured. Videoconference systems cannot operate over 802.11 WiFi wireless network. 8.1 Videoconference subnets The network point is automatically configured onto a correct videoconference specific VLAN and subnet. IP address allocation is to be done by assigning a static IP to the MAC address of the unit. The IP address is hardcoded into the videoconference unit and managed remotely via TMS. (Note: as above: videoconference units cannot be connected wirelessly.) 8.2 ISDN ISDN calls are not supported internally within Deakin. All videoconferences held internally are via IP. External parties may use ISDN to call into the Deakin videoconference MCU/bridge, which provides an ISDN adaptation service, however IP is preferred. Individual endpoints do not support ISDN dialling. ISDN bandwidths of up to 768 kbit/s are supported into the videoconference bridge. Deakin eSolutions Page 49 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 9 Central video communication infrastructure 9.1 Video bridging using Codian Multipoint Control Unit (MCU) Video bridging services are provided using the Cisco/Codian infrastructure summarised in the table below. Contact the DeS AV and Networks Unit Leader for further technical details. Attribute Production bridge Hardware Cisco Codian MSE 8510 and 4520 MCUs External access Open to external IP and ISDN Protocols H.323, SIP; H.320 (ISDN) Addressing Fixed IP, E.164, URI and ISDN addresses More information http://www.deakin.edu.au/its/videoconference/technical.php 9.1.1 Dialling syntax The current dial-string syntax for dialling the Deakin MCU services are as follows: E.164: (+613)522xxxxx (preferred) URI: [email protected] IP: xxx.xxx.xxx.xxx ISDN: (+613) 522 xxxxx Remote sites that are members of the AARNet E.164 federation use the E.164 format. Desktop videoconference participants (e.g. using Cisco Jabber) use the URI format. IP is provided as a lowest common denominator (safety net) for external participants that cannot use E.164 or URI dialling. 9.1.2 Telephony participants Telephony participants can join a video conference from any phone: internal Deakin Cisco VoIP phone, voicepoint audio conferencing unit, external landline or mobile telephone. Videoconference sessions are dialled from telephones using the same normal (+613) 522 xxxxx telephone numbers as would a video participant in the same session. 9.1.3 Session types The Deakin MCU infrastructure supports:  Ad hoc (permanent) Virtual Meeting Points – end-user dial-in whenever required  Booked VMPs – booked via Deakin’s Outlook/Exchange Calendar  Booked sessions – automatic dialout to pre-booked destinations (primarily for teleteaching sessions) Deakin eSolutions Page 50 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 9.1.4 Multipoint screen layouts The Deakin MCU infrastructure supports a wide variety of screen layouts suitable for different multipoint session formats. The following Deakin standard layouts are defined and promoted: Layout Name Description Ideal for sites Suitable for sites Side-by-side “2+” Default layout for all production sub-‘SD’ (SD448) MCU services. Two equal sized main images across the centre, plus 8 additional small images. Voice-activated switching so that most recent talkers are displayed in the large main images. 3 3 ~ 11 Telepresence “1+” Default layout for all production HD ‘Telepresence’-style MCU services. One large image, plus 6 additional small images in the ‘film-strip’ along the bottom. Voice-activated switching so that most recent talker is displayed in the large main image. 3~8 3~8 Grid “4+” Equal sized grid of images, auto-ranging between 2x2, 3x3 and 4x4 layouts depending on number of participants. 5 3 ~ 17 Note: number of sites includes the near-end, e.g. 5 sites means yourself plus 4 remote sites. Note: sub-‘SD’ means SD448 (cf full-SD which is SD576) Different default layouts can be configured on a per-VMP basis. During a session, different layouts can also be selected by the end-user. Other formats are available for niche applications (e.g. very large conferences) and these can easily be made available on request on a case-by-case basis. 9.2 Video communications servers (VCS) H.323 Gatekeeper services are provided by two Cisco/Tandberg Video Communications Server devices. 9.3 Firewall traversal (Expressway) IP address translation and firewall traversal services are provided by two Cisco/Tandberg Video Expressway devices. 9.4 ISDN Gateway ISDN to IP (H.320 to H.323) translation services are provided by two Cisco/Tandberg 3241 ISDN Gateways. Deakin eSolutions Page 51 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 9.5 Videoconference recording (IPVCR) Deakin University does not currently offer an IPVCR service and refers clients needing this service to AARNet. http://www.aarnet.edu.au/services/support/nvcs.aspx Alternatively, a teleteaching session can be recorded via iLecture where fitted to the teleteaching lecture theatre, usually at the Presenter end. Deakin eSolutions Page 52 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 10 Configuration 10.1 Cisco Telepresence Management Suite (TMS) All units supported by DeS are to be managed using the Cisco Telepresence (formerly Tandberg) Management Suite (TMS). A unit will not be supported if it is not added to TMS. Configuration form is available from DeS AV and Networks Unit (refer ICT Volume 2.7 Design Calculators, Tools and Resources for details). 10.2 Configuration Templates This system specifies a number of Configuration Templates to be deployed. The appropriate Configuration Template should be deployed to the unit. Configuration Templates are designed so that units across the fleet have consistent settings for interoperability and easy support. Additional Configuration Templates are used for special purposes such as diagnostics. 10.3 AMX Controlled Rooms    If AMX Modules are used, the module version must be compatible with Deakin’s current Tandberg firmware version. RS-232 Control for the video conference endpoint must be set to - BaudRate: 9600 - Parity: None - DataBits: 8 - StopBits: 1 GUI: Set the Default Call rate for Manual Calls to “Max” not “Auto”. (Auto will call at a maximum of only 768 kbit/s) Deakin eSolutions Page 53 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11 Environment Tighter lighting and interior design requirements apply to all videoconference spaces, as compared with normal office or teaching spaces, particularly due to the demands of the video camera and audio system as regards:  brightness (in particular avoidance of low lighting levels which result in video noise that overloads the video compression algorithm);  uniformity of brightness (to avoid hot-spots due to the lower dynamic range of video cameras as compared with the human eye);  positioning of lighting to avoid shadows on participants’ faces;  positioning of lighting to avoid washing out contrast on displayed images (we spend significant money on high-contrast / high-brightness display technology, so we must not destroy the effect by flooding the presentation surface (whether projected or LCD) with inappropriately placed lighting)  colours – in particular of table tops (to correctly in-fill shadows while not overexposing camera) and walls;  uniform colour temperature for all lighting in the space (no mixture of different types of lights);  reduced contrast range (i.e. of luminosity) between the various colours in the space;  interior room decoration: needs to strike a balance between not too much fussy detail while still engendering a normal comfortable meeting room environment, in particular need to avoid fine detail (e.g. fine grid patterns on fabrics, blinds, etc.) that interact badly with the camera). A reasonable compromise can be adding some minor contrasting feature on the side walls (e.g. curtains for sound dampening), or a slightly contrasting wall colour on the sides cf the rear wall;  background suitable for correct functioning of auto-focus camera, in particular:  fine-detail in-shot but at a different distance from the camera than the participants can cause the camera to focus on the artefact rather than on the subject;       conversely, suitable detail at a similar distance (e.g. just behind) a participant can prevent the camera from ‘hunting’ while trying to focus on an excessively blank background (minimizing distance between participant and background is therefore called for – e.g. suitable tables that comfortably fill the room rather than leaving large unused areas between tables and walls) signage to be of adequate size to be easily readable, even in wide-shot (with the progressive growth of external videoconferences it is important to include Deakin branding in all spaces); no high gloss surfaces: reflection of lighting or screen images back into camera (in particular rear wall – must avoid whiteboards, glass and other high gloss surfaces); no bright direct light into camera lens (even off-axis / out-of-shot); windows must be avoided, in particular:  openable windows (inadequate sound isolation)  windows in-shot (distraction of people and things moving past outside  windows that allow in external light (excessive contrast due to sunlight patches)  windows on rear wall (reflection of screen images back to viewers at the other end)  windows in-shot covered in vertical blinds or venetian blinds camera hyper-sensitivity to blue light; Deakin eSolutions Page 54 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards  acoustic treatment to minimize echo, reverberation and noise is very important for successful videoconferences – poor sound is the single biggest cause of problems during videoconference sessions. 11.1 Lighting Normal office lighting levels will be adequate, i.e. around 500 Lux, and an intermediate or ‘warm’ colour (equivalent colour temperature 3000-4000 Kelvin) will give acceptable pictures and emit a comfortable light for the participants. Glare for the participants shall be avoided. The minimum brightness of the room shall be 400 Lux. Diffusers, preferably incorporating uplighting, shall be used to eliminate all sharp shadows and to produce the most uniform brightness balance throughout the space. Care shall be taken to ensure that there are no hot-spots on the walls, e.g. do not position lighting too close to walls. Lighting shall not be installed near the presentation surfaces. Directional diffusers shall be used for lighting near the presentation surfaces sufficient to prevent light bleed onto the presentation surfaces (regardless of whether LCD panel or projector). High contrast ratio of the presentation technology is to be preserved. Front-of-house lighting (i.e. lighting near the presentation surfaces) must be separately switched in all circumstances, i.e. minimum two-way split system, with independent end-user control of front-of-house and audience lighting must always be provided. ‘Scenes’ provided by integrated lighting control systems must preserve the independence of the front-of-house and audience controls – i.e. these must not be re-linked by the ‘scene’ controller. In all circumstances, the default setting for the FoH lighting circuit is OFF – the end-user must be required to explicitly turn on FoH lighting in whatever unusual circumstances they feel they need it. Fittings should be arranged so that a higher level of illumination is produced in front of the participants than either above or behind them so as to prevent excessive shadows on faces. It is mandatory that there be no direct lighting or glare into the camera lens (even off-axis / out of shot) as this may cause the auto iris to close up excessively, or generate visible reflections within the lens system. Approved lighting control systems are specified in the companion 2.2 Audio Visual Technical Design Standards document. 11.1.1 Mixed type lighting not to be used Lights of different types (e.g. fluorescent and LED) are not to be incorporated into the same space. Lights of different colour temperature are not to be incorporated into the same space, unless these are fitted within the one luminaire and mixed within the fitting so as to produce a single broader and/or controllable spectrum, e.g. RGB LED arrays; or Phosphor-LED arrays comprising a mixture of 3000 K and 4000 K LEDs within the one assembly are acceptable. Neither incandescent nor halogen lighting shall be used. There are no exceptions to this requirement. For example: even spot-lighting for presenters in large lecture theatres (AV08) can be provisioned using LED spotlights of the same colour spectrum as the room lighting. Deakin eSolutions Page 55 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11.1.2 Fluorescent lighting Fluorescent lighting is an acceptable lighting choice, subject to the following requirements. Normal office lighting levels will be adequate, i.e. around 500 Lux, and an intermediate or ‘warm’ fluorescent colour (equivalent colour temperature 3000-4000 Kelvin) will give acceptable pictures and emit a comfortable light for the participants. 11.1.3 LED lighting This section contains best available preliminary guidelines, subject to change once the industry has accumulated some field experience with this new type of lighting. LED lighting should be tested in situ via the videoconference PHD camera before installation or design signoff. ‘White’ LED lighting is an acceptable lighting choice, subject to the following requirements. Currently only Phosphor-LED arrays are allowable. Brightness Normal office lighting levels are adequate, i.e. around 500 Lux. Colour spectrum – Phosphor-LEDs Equivalent colour temperature shall be in the 3000-4000 Kelvin range. Phosphor-LEDs with excessive blue bleed are not acceptable. The PHD camera is over-sensitive to blue bleed and will produce pictures with an exaggerated blue hue. For example, the spectrum to the right illustrates a Phosphor-LED spectrum that is NOT acceptable. base diagram source: http://en.wikipedia.org/wiki/Light-emitting_diode The power density should be approximately flat throughout the red and green part of the spectrum, and the blue peak should not exceed the luminosity across the rest of the spectrum. Phosphor-LEDs with an equivalent colour temperature above 4000 K are NOT acceptable. LED flash rate Preliminary and For further study. Minimum requirement is to exceed equivalent parameters for typical fluorescent lighting. The following regimes are considered acceptable:  LEDs permanently illuminated (i.e. LED duty cycle = 100%)  Emulation of characteristics of typical fluorescent lighting, approximately: LED flash rate: 100 Hz LED duty cycle: >50% LED persistence: >3 ms  Other (for further study) Deakin eSolutions Page 56 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11.2 Window treatment A room without windows is preferred as a videoconferencing space. However, if a room with windows is the only option, window treatment will be necessary to control lighting conditions. In particular:  no direct sunlight shall enter any part of the room at any time of the day or year;  glare and reflections onto the screen(s) must be prevented;  glare from behind the screen(s) must be prevented. The preferred method of window treatment is heavy curtains which block out all light from windows. The drapes shall have a solid colour, without pattern, in appropriate tones and loosely gathered while still being in keeping with the tones of the room. Curtain/blind colours shall be as defined in section 1.1 of ICT Resource 2.3.2. Drapes may be of contrasting colour to the wall, but drawn from the same approved palette. Fabrics shall not be of course weave. Venetian (and micro-venetian) blinds are NOT to be used under any circumstances. Vertical (venetian) blinds are NOT to be used under any circumstances. 11.2.1 Automated block out blinds If heavy curtains are not possible due to building design, it is possible to use block out blinds instead. If installed, automated blinds will be of the type below. Manufacturer Model Reflex Shading Systems RB95 or equivalent Installation requirements The blinds should be hardwired using a Somfy controller, connected to the AMX room control system if an AMX controller is installed. If an AMX controller is not installed, then the blinds will be controlled by the soft button panel provided with the product. 11.3 Colour scheme 11.3.1 Prohibited colours, patterns and finishes Prohibited colours, patterns and finishes in-shot:  Bright red, dark red  Black, White  Reflective and high gloss surfaces  Fine line and grid patterns  Venetian blinds (vertical, horizontal and micro)  Course weave in fabrics Deakin eSolutions Page 57 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11.3.2 Table tops White (and near white) table tops are NOT acceptable. Black (and other dark) table tops are NOT acceptable. High gloss table tops are NOT acceptable. A lightish colour (e.g. light oak wood-grain), but not white, is preferred, so as to infill shadowing under participants’ faces. Mid brightness colours are also acceptable (e.g. mid-brown woodgrain). Wood-grain, two-tone and solid colour surfaces are all acceptable. Table colour should contrast with wall colours. 11.3.3 Wall treatment In order to provide a high quality image, the subject needs to have sufficient contrast with the background. The wall that the camera(s) is facing toward and the side walls shall be painted using colours from the palette as given in section 1.1 of ICT Resource 2.3.2 Interior Design for Videoconference Spaces. For contrast and interest, the side and rear walls may be painted in different colours. Matt paint shall always be used to minimize reflections. 11.3.4 Wall behind LCD panels The wall behind the LCD (or Plasma) panels shall be painted using a colour from the palette as given in section 1.2 of ICT Resource 2.3.2. 11.3.5 Ceiling Where video projectors are employed, so as to minimize re-reflection of light from the ceiling back onto the image surface, the ceiling above the Front-of-House area (AV06 and AV08) shall be painted using a colour from the palette as given in section 1.4 of ICT Resource 2.3.2. Paint type must be zero-gloss ceiling type paint. In all other situations, ceiling areas shall be painted zero-gloss ceiling white. 11.4 Interior decoration Videoconference rooms should strike a balance between looking as natural and normal as possible, while not having excessive detail, distractions or features that will disturb correct operation of the camera. In particular:      Fine grid-patterns (e.g. on fabrics, blinds, curtains and table tops) must be avoided (these generate unacceptable interference patterns in the camera – due to aliasing between the fabric grid and the image sensor’s internal grid structure); Detail at distances different than the subjects are to be avoided (these can cause the auto-focus camera to focus in the wrong things; Conversely large blank expanses can cause the camera focus to ‘hunt’ due to inadequate detail in-shot; Small details and decorations must be avoided; interior designers shall take into consideration the >10x zoom range of the camera, which means that: o small items will look too fussy in wide-shots; conversely Deakin eSolutions Page 58 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards o   even barely noticeable grid textures on fabrics can generate disturbing interference patterns when the camera is zoomed-in; o signage and branding must be larger in size than normal (otherwise looks ridiculously tiny in wide-shots); Decorations, if any, should not contain large expanses of white, red or black; Windows in-shot must be particularly avoided where they allow the viewer to see movement of people and things in the external world (very distracting for the viewers). High gloss surfaces must be avoided to minimize reflections. In particular paintings/prints/photographs and whiteboards (which also have high gloss surfaces) should be angled so as to not directly face the camera (so that they do not reflect the screen image back into the camera. Protective glass covering paintings/prints/photographs, if any, should be replaced by non-reflective matt glass. Whiteboards are generally not satisfactory for use in video conferences. A superior alternative is a SmartBoard integrated into the videoconference system (via the system PC). In dual display spaces, the SmartBoard replaces the 2nd (right side) content display. In this case, the left (live video) display shall be the same size, brightness and aspect ratio, i.e. a UST video projector of same type shall be used and not an LCD panel. 11.5 Signage Wall signage is optional. Where signage is employed, only the official Deakin crest and/or corporate logo shall be used, using their correct colours, fonts and layout. Where not specified by the official artwork, the background colour shall be the wall colour. The signage may identify the venue in 5 words as: “Deakin University Australia campus” Where signage is employed it shall be sufficiently large to be easily read even when the camera is set to its widest shot. Smaller signs look ridiculous at the far-end of the video link. Standard artwork and styles is specified in section 2 of ICT Resource 2.3.2. 11.5.1 Presenter’s desks (AV06, AV08) The front of a presenter’s desk (i.e. facing towards the audience and camera) shall be signed using the corporate logo (e.g. the “Deakin flowers” logo) if such exists, plus the University’s official crest, using their correct colours, fonts and layout. Where not specified by the official artwork, the background colour shall be white. The signage shall identify the venue in 5 words plus room number as (sample as per section 2.2 of ICT Resource 2.3.2): “Deakin University Australia campus” The signage shall be as large as possible that will fit across the entire width of the presenter’s desk. Deakin eSolutions Page 59 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11.6 Acoustics and acoustic treatment 11.6.1 Acoustic isolation The overall acoustic design shall provide a minimum 45 dB (preferably 50 dB) attenuation of sounds into or out of the room. Note this is the total over all paths, whether through walls, doors, ceilings, windows or direct transmission through floors or building fabric. Wall insulation must take into consideration sound bleed through ceiling spaces above walls – suitable ceiling insulation and/or sound blankets in the ceiling space above walls must be fitted so as to preserve overall isolation requirement. For example, if there are two equal dominant sound paths through wall and ceiling each must achieve 53 dB on its own so as to preserve an overall attenuation of 50 dB. 11.6.2 Noise Ambient sound in the room shall not contain any distinctive characteristics such as tones or fluctuations. Air conditioning, external noise and other plant noise shall not exceed NR35 as defined by AS 2107 2000. Openable windows are unacceptable; if unavoidable these are to be fitted with heavy curtains, and both the windows and curtains shall be kept fully shut during videoconference sessions. In particular, noise floor target range, to be measured with HVAC systems running, is 30 to 40 dBA and must not exceed:   45 dBA anywhere in the room; and 40 dBA at any of the microphone locations. 11.6.3 Reverberation Reverberation times are defined at AS 2107 2000. In particular, reverberation time target range is 0.3 to 0.4 s and must not exceed:   0.6 s for controlled spaces with both fixed furniture and fixed microphones 0.5 s for uncontrolled spaces with flexible furniture and/or movable microphones 11.6.4 Acoustic treatment Acoustics of the space is very important for successful videoconferencing and will be determined during the audit phase, pre installation and will specify the following acoustic treatment under these circumstances: Acoustic dampening: is required in rooms that have significant echo, exceeding the above reverberation limits. Noise cancellation: is required when noise floor exceeds 40 dBA. As a last resort if natural noise floor cannot be brought within limits specified here by other means, noise cancellation shall be achieved through the use of the ClearOne Converge Pro 880 DSP, but only if: the natural noise floor is below 50 dBA everywhere within the room; AND the noise is of a type that can be effectively reduced (e.g. continuous white noise but not background crowd noise). The device shall be adjusted so as to deliver a noise cancellation of no more than 10 dB. A natural noise floor above 50 dBA is unacceptable and cannot be rectified electronically Deakin eSolutions Page 60 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards Echo cancellation: is an integral requirement of any videoconference system; it is preferably performed natively within the codec; or alternatively within a ClearOne DSP where fitted. 11.7 Table layouts The arrangement of tables and chairs can significantly affect the videoconferencing experience. The following layouts illustrate different videoconferencing installations. 11.7.1 AV02 – Executive Office There are 3 layouts for AV02: EX90 (with or without 2nd 24” monitor):  A: On Executive Desk (in place of PC monitor);  B: On small meeting table;  C: On credenza separate from but adjacent to small meeting table Correct viewing distance from screen:  Minimum: 0.65 m  Maximum: 2.0 m Type of space Acceptable table layout Personal office EX90 on desk, person seated on chair facing desk (with or without 2nd 24” monitor): (AV02) EX90 on credenza, persons seated on small round table (with or without 2nd 24” monitor): Deakin eSolutions Page 61 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11.7.2 AV04 – Meeting room Preferred layouts (‘immersive telepresence’ style):  Wide arc  Wide ‘V’  Wide trapezoid  Wide rectangle  Absolute minimum depth for wide format tables 750 mm (preferred min 900 mm) Acceptable layouts:  ‘U’, half oval  Square  Long trapezoid Non-preferred layouts (poor local and videoconference sight-lines):  Oval use Half oval or other acceptable layouts in preference  Long rectangle use Trapezoid or other acceptable layouts in preference Absolute minimum width for Long format tables 1000 mm (preferred min 1200 mm) Type of space Acceptable table layout Small meeting room Videoconference unit wall mounted, e.g. above credenza, persons seated on small round, oval, square or rectangular table: (AV04) Deakin eSolutions Page 62 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards Larger meeting room (AV04) Preferred: Videoconference unit wall mounted, wide arc, open ‘V’ or wide rectangle table: Acceptable: Videoconference unit wall mounted, ‘U’, half oval, square, short rectangle, or trapezoid table, e.g.: Deakin eSolutions Page 63 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards Non-preferred: Videoconference unit wall mounted, long rectangle or oval table: 11.7.3 AV06, AV08 – Teaching spaces Type of space Acceptable layout Teaching space (AV06, AV08) Deakin eSolutions Page 64 of 78 Version: 3.1 2013 ICT 2.3 2013 Videoconferencing Standards 11.8 Camera and viewing angles Cameras will be positioned centred with respect to both the table and the displays and angled as per the following specifications: Type of space Standard camera arrangement Personal office EX90 units shall be placed directly on the desk, small meeting table or nearby credenza. If on credenza, the credenda shall be of the same height as the meeting table. The camera of the EX90 shall be positioned at a height of between 1.2 and 1.4 m. This height places the camera at eye level with participants seated. The EX90 inbuilt camera is manually directed towards the participant(s) and focussed accordingly. (AV02) Meeting room (single screen) (AV04) The single Precision-HD Camera shall be positioned at a height immediately above (not below) the display. This ensures that the eyeline as viewed from the far-end is close to and a little downwards from eye-to-eye. This is preferable to appearing to look above eye-toeye – it is normal for people to be looking a little downwards (e.g. looking at papers), indeed this is expected respectful behaviour in some cultures, whereas looking over someone’s head always appears decidedly odd. If a camera placed above the display produces camera angles that are too acute (as defined at section 11.9.4), this indicates that the screen is mounted too high and/or the chosen screen size is too large for the size of the room – in which case a smaller screen is required – choose from the table at section 11.9.1 below. If this still produces acute camera angles, upgrading to a dual screen system is indicated, with camera mounted at correct height between the displays as below. The camera shall automatically adjust to focus on participants. Meeting room (dual screen) (AV04) Teaching space / Lecture Theatre (AV06 / AV08) Deakin eSolutions The single Precision-HD Camera shall be positioned at a height as determined by the formulae at section 11.9.4 (not below 1.2 m and generally below 1.8 m AFFL). Usually between the displays, or sometimes immediately above the displays, but not below the displays. This height places the camera at eye level aligned with the typical Far End image, and hence optimum perceived eye contact angle. The camera shall automatically adjust to focus on participants. Teaching spaces shall have at least two cameras. One shall be positioned at the rear of the venue, directed toward the presenter. The other camera shall be mounted in the centre of the front wall (between dual projected images), directed toward the audience.

Where this is not possible (e.g. clearance required to minimize risk of bumping, damage theft, camera shall be between 2100 mm and a maximum of 2500 mm AFFL. Camera 2 shall be mounted between 2100 mm and a maximum of 2500 mm AFFL. For AV06, camera is normally mounted on the rear wall. For AV08, camera should be mounted sufficiently forward in the theatre so that it can be zoomed in to capture a head-and-shoulders close-shot of the presenter – this could require mount descending from the ceiling, which must be sturdy and vibration free. Laterally, the camera should be positioned so that the presenter, when at their normal position behind the presenter’s desk, is looking directly towards the camera when looking at the exact centre of the auditorium.
