By using Array’s hardware to perform audio acceleration during your NetMeeting Internet use, the VideoONE Communicator provides enhanced audio and video quality in addition to reducing your PC’s CPU utilization – this will improve NetMeeting’s whiteboard and data collaboration (T.120) performance. Based on Array’s proprietary VideoFLOW® H.261 Codec chip technology, the VideoONE Communicator delivers the highest quality video in CIF, QCIF or SQCIF* resolutions and at various frame rates. The VideoONE Communicator provides a user-friendly GUI, by using the same NetMeeting GUI, to enable you to perform high quality face-to-face video conferencing meetings with friends and colleagues without the difficulty of learning a new application. The VideoONE Communicator offers a full video communication solution for delivering digital video and audio content over an Intranet. With Array’s H.261-compliant video hardware acceleration – for high quality, real-time digital video, and G.723-compliant audio hardware acceleration – for crisp digital audio using acoustic echo cancellation, the VideoONE Communicator is the ideal solution for low cost, high quality video conferencing. In addition to the advanced video conferencing capabilities, the VideoONE Communicator is also a high quality, real-time MPEG-1 capture board. It is designed to be compatible with many third-party streaming and editing software – so that you can take full advantage of applications, such as Web Page Content creation & streaming, Video CD creation & editing, Training, Video E-mail, and Archiving to name just a few.

Refer to Appendix D for detailed information on adjusting the Array desktop video camera (included with model VF300-C only). It is recommended that you adjust all video and audio settings prior to making a conference call. Making a NetMeeting Call 1. Click “Call” button. A “New Call” dialog box appears. 2. Enter “Address” information of the person you are calling. The “Address” pull-down list shows the previous calls that you have made with NetMeeting. If this is the first time 15 3. 4. you are making a NetMeeting call, you will need to enter the address information of the person you are calling. The address information can be in the form of an IP (“123.123.12.123”) or Host (“computer.domain.com”) address format. Select a supported address format type from the “Call using” pull-down list. Most IP and Host address formats are classified as “Network (TCP/IP).” It is recommended that you select “Automatic” if you are not familiar with the different address formatting types – so that Microsoft can automatically detect it for you. Click “Call” button to initiate the video conferencing call. Answering a NetMeeting Call 1. “Incoming call from John Doe…” dialog box appears. The NetMeeting application does not have to be the active window, but the application must be running or open in order for NetMeeting to detect any incoming calls. When someone is trying to call you, NetMeeting notifies you of the incoming call with the “Incoming call from John Doe…” dialog box on the lower right corner of your screen, and allows you to accept or decline the call. 2. Click “Accept” to answer the call or click “Ignore” to decline the call. If the NetMeeting application is minimized, accepting a call will bring up (maximize) the NetMeeting application window. NetMeeting offers three options to accept calls: Do Not Disturb, Auto Accept, and Auto Start. Do Not Disturb can be enabled or disabled through NetMeeting’s main menu: Call > Do Not Disturb. A check next to Do Not Disturb indicates that NetMeeting will not ring or notify you if someone attempts to call you. NOTE: this setting is not saved when you close or exit the NetMeeting application. Every time you restart NetMeeting, Do Not Disturb is disabled. Simply go to Call > Do Not Disturb to reactivate it. You can find the Auto Accept option under the General tab of the NetMeeting Properties dialog box. Check this option if you want NetMeeting to automatically accept all incoming calls. Generally, you only want to check this option if your computer is unattended. This feature is not convenient for those who want to know who is calling before they answer a call because NetMeeting automatically accept all incoming calls. Selecting Auto Start is useful if you are always connected to the Internet or a LAN. This option automatically initiates the NetMeeting application every time Windows starts up. A NetMeeting icon in the task bar indicates that the application is opened. Double-clicking the icon will open and run NetMeeting. To return the application to the task bar without terminating it, go to NetMeeting’s menu Call > Exit. Ending a NetMeeting Call 1. To end a NetMeeting call, simply click “Hang Up.” 3.2 NetMeeting Options: Video/Audio Codec Selection By clicking the NetMeeting Options button, you can select the VideoONE Communicator CODEC or the NetMeeting CODEC. You need to select a CODEC before starting a video conferencing session. Otherwise, the default “VideoONE Accelerated Video and Audio” option will be used. Also if you choose a different selection other than the default, then you must end all NetMeeting calls, close the NetMeeting application, then restart NetMeeting in order for the new setting to take affect. There are three options: VideoONE Accelerated Video and Audio, VideoONE Accelerated Audio with Microsoft Video, and Microsoft Software Video and Audio Codec. These options allow you to choose the Codec configuration that is optimum for your installed network. 16 VideoONE Accelerated Video and Audio Option This option enables NetMeeting to take advantage of the VideoONE Communicator video and audio hardware Codec. Selecting this option will improve the video and sound quality, and will increase your PC’s available CPU power so that your computer can perform other NetMeeting applications, such as whiteboard and data collaboration. Since the VideoONE Communicator is the only NetMeeting hardware accelerator available today, and because this option also offers the highest audio and video quality, it is highly recommended that you select this option if you have a network connection of 128Kbps or faster (ie. ISDN, LAN, WAN). To accommodate bit rates below 128Kbps over Internet or Plain-Old-Telephone-Services (POTS) networks, two options are available: VideoONE Accelerated Audio and Microsoft Video Option This option utilizes the VideoONE Communicator audio hardware Codec and the Microsoft software video Codec. This option is recommended if you are using the Internet or an analog modem (ie. 28.8K, 33.6K, 56K, etc.) for your video conferencing connectivity. With this option, near toll quality audio will be achieved without hisses and pops – which are the two most common symptoms of software audio Codecs. In addition, by utilizing the VideoONE Communicator audio hardware Codec, more CPU utilization is available to perform other tasks that can enhance your overall video conferencing experience, such as better video quality, whiteboard application, and other data collaboration. The VideoONE Communicator video and audio hardware Codecs are best utilized at bit rates of 128Kbps or higher. Also, your video conferencing quality depends on the overall connection speeds – your connection as well as the person you are calling. To get the most out of your video conferencing experience, you should use this option if you have a highspeed connection but the person you are calling is using a slower one. Microsoft Software Video and Audio Codec Option In the event that you want to use the Microsoft software Codecs, select this option. With this option, NetMeeting will utilize Microsoft’s software audio and video Codecs. NOTE: You can change the CODEC Selection settings at any time, but in order for the settings to take affect, you must end all NetMeeting calls, close the NetMeeting application, then restart NetMeeting. 3.3 NetMeeting Options: Bit Rate Selection The Bit Rate (Kbps) option modifies the quality of the video and the overall performance of the video conferencing session. The higher the bit rate, the better the video quality. However, the more bandwidth will be required. The NetMeeting Options primarily define your network’s bandwidth. The Bit rate default is set at 512Kbps, but depending on your network’s bandwidth or restrictions, you may select 128Kbps, 256Kbps, 384Kbps, or 512Kbps. If you select a bit rate that is higher than what your network is capable of handling, your overall video conferencing session may not function properly. NOTE: You may change the Bit Rate selection at any time, but in order for the settings to take affect, you must end all NetMeeting calls, close the NetMeeting application, then restart NetMeeting. 3.4 Advanced There are two diagnostic tests that can be used to troubleshoot the VideoONE Communicator product: Hardware and Network. These two diagnostic tests will be implemented in the future VideoONE Communicator release as a free software upgrade. 3.5 Launch VideoONE Recorder Application Clicking the Array butterfly button from the VideoONE Communicator Panel will start the VideoONE Recorder application. This application is identical to Array’s VideoONE Recorder product. It enables quick and easy MPEG capture and compression. Refer to Section 4.0 of this guide for more detailed instructions on how to use the VideoONE Recorder Application. 17 4.0 VideoONE Recorder Application The VideoONE Recorder Application is an easy-to-use platform to capture and playback real-time MPEG-1 video and audio for a variety of multimedia applications. 4.1 Starting the Application To start the VideoONE Recorder Application, you will need to launch the VideoONE Communicator Panel. Refer to Section 3.0 for more information about the VideoONE Communicator Panel.

It can be stopped manually – using the “Press Stop” button or automatically – using either “Size Limit” or “Time Limit” option. Volume* Controls the line out audio level. It does not affect the captured audio volume. Balance* Controls the right and left audio levels. It does not affect the captured audio balance. Mute* Enables or disables the audio output volume. It does not affect the captured audio volume On Top If it is checked, it enables the VideoONE application window to always remain on top of other application windows. *Use your PC’s mixer control during playback.(speaker icon in Windows.) 20 4.6 Using Microsoft ActiveMovie for Playback The VideoONE Communicator uses Microsoft ActiveMovie MPEG-1 Player to playback captured MPEG-1 video clips. The Play button on the VideoONE MPEG application will start the ActiveMovie player with the current video file opened for playback. Press the Play button in the ActiveMovie player to start the playback of the captured video clip. 4.7 Storage Statistics The VideoONE MPEG application will display storage statistics that are useful to know before starting a capture session. The statistics are shown as kilobytes available and the corresponding amount of time that the video and audio can be recorded at the selected bitrate. NOTE: The amount of storage depends on your computer’s hard drive space, the amount of video/audio being captured, and the specified compression settings. Figure 4.4 - VCR Control Storage Statistics The capture session should be stopped before it reaches the maximum storage space capacity, which is specified under “Storage Available.” During a capture session, the segment values are reset to zero each time you depress the “Pause” button. The “Total” and “Segment” statistics are the same after ending or starting a capture session. NOTE: If the captured content is larger than your storage capacity, the VideoONE Communicator will stop recording. Storage Item Available Total Segment 4.8 Description Shows the available hard drive storage space (in kilobytes and time) based on the selected compression settings. Shows the total space (in kilobytes and time) used for a complete captured file. Shows the space used (in kilobytes and time) for a previously captured segment only. The Segment statistics will match the Total statistics only after the capture is finished or stopped. The Segment statistics will start at zero once pause is pressed during a capture session. Compression Tab The Compression tab in the VideoONE MPEG application gives you access to all the MPEG-1 video and audio compression options necessary for real-time capture. A set of pre-defined compression options, referred to as Templates, are available for quick and easy MPEG-1 video capture. You can easily select one of the pre-defined templates or choose User Defined to customize your own settings. 21 Figure 4.5 - VideoONE Communicator Compression Tab 4.8.1 Compression Option Templates Templates are available to set the appropriate compression options to capture video for specific applications. The compression options will be different depending on the use of the captured movie. For example, movies captured to create a VideoCD must adhere to the White Book specifications. Selecting the “VideoCD” template enables the VideoONE Communicator to automatically set the compression settings that are required by the White Book specification. When you select a pre-defined template, all the compression settings are grayed-out (disabled). This indicates that the VideoONE Communicator will automatically use the pre-set configurations (as defined by the template’s specifications) to capture your content. “User Defined” templates are available for more advanced users – those who understand the MPEG-1 specification options in order to create custom MPEG movies. Clicking the “Save” button, located next to the template box, enables you to save a “User Defined” template so that you can use it in the future. Template Frame Rate Resolution Video Bitrate I Frame Video CD 29.97 SIF (352*240) 1152000 15 VCR Quality 29.97 SIF (352*240) 1152000 15 Max Quality 29.97 SIF (352*240) 3072000 15 Presentation Clip 29.97 SIF (352*240) 512000 15 Video Mail 29.97 QSIF (176*120) 112000 15 Audio Mail N/A N/A N/A N/A User Defined ≤ 29.97 SIF or QSIF Variable 0-132 See Spec 22 P Frame 3 3 3 3 3 N/A 1, 2 or 3 Sample Rate Audio Bitrate Stream Type 44100 224000 V+A 44100 192000 V+A 44100 224000 V+A 44100 64000 V+A 44100 64000 V+A 32000 64000 A Only 32000 Variable V+A, A, V 44100 See Spec 48000 Table 1 - Compression Option Template Settings for NTSC Template Video CD VCR Quality Max Quality Presentation Clip Video Mail Audio Mail User Defined Frame Rate Resolution Video Bitrate 25 SIF (352*288) 1152000 25 SIF (352*228) 1152000 25 SIF (352*288) 3072000 25 SIF (352*288) 512000 25 QSIF (176*144) 112000 N/A N/A N/A ≤ 25 SIF or QSIF Variable See Spec.

For the “User Defined” templates, the video mode and audio mode settings in the “A/V Settings” tab will affect the available frame rate settings and audio bitrate settings in the “Compression” tab. For example, if the audio mode is set to stereo, the minimum bitrate available for MPEG-1 audio is 64000 because 64000 is the minimum audio bitrate for stereo MPEG-1 audio streams (as defined in the MPEG-1 specification). The minimum audio bitrate available will automatically change to 32000 if the audio mode is set to mono because 32000 is the minimum audio bitrate for mono MPEG-1 audio streams. Most users are unaware of these requirements mandated by the MPEG-1 specification. Therefore, it is recommended that you use one of the pre-defined templates for creating MPEG-1 movies. Selecting a pre-defined template insures that the compression settings for your capture session will yield a valid and readable MPEG-1 content. 4.9 Audio and Video Settings Tab The “A/V (Audio/Video) Settings” tab in the VideoONE MPEG application is used to select the audio and video settings for the VideoONE Communicator board. The settings include:Video Input (Composite or S-video), Video Mode (NTSC or PAL), Audio Mode (stereo or mono), Video Adjustments (brightness, contrast, hue and saturation), and Audio Gain (right and left input channels). The video and audio input source and mode should be set to match your video and audio source. The video adjustments should be made prior to starting your capture session. You can view the effects of the video adjustments in the VideoONE Overlay window. Figure 4.6 - VideoONE Communicator A/V Settings Tab 23 4.9.1 Adjusting Picture Quality The video adjustments will affect the picture quality for the VideoONE Overlay window and for the captured video. The video adjustments should be made prior to capturing video. 4.10 Basic MPEG-1 Capture & Playback Tutorial The VideoONE Communicator application makes capturing video for any application easy. The following set of instructions is a short tutorial to show you how to capture and playback a simple MPEG-1 session. There are only a few basic steps required to capture high digital-quality video and audio. NOTE: The goal of this tutorial is to create a VideoCD content. It is also assumed that you have properly installed all the necessary hardware and software as mentioned in the Installation section of this guide. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Start the VideoONE MPEG application. Un-check the “Mute” option, so that you can hear the audio. Start your video source. This will enable you to preview the video in the VideoONE Overlay window. Select the “Compression” tab from the VideoONE Communicator Application. Select “VideoCD” from the “Template” pull-down options box. Select the “A/V Settings” tab. Verify that the “Video Input” and “Video Mode” settings are correct. If the settings are incorrect, the video will not display or it may not display properly in the VideoONE Overlay window. Adjust the video quality using the “Video Adjustment” settings. You can adjust your video’s Brightness, Contrast, Hue, and Saturation. You can view the effects of the changes in the VideoONE Overlay window. Select the “VCR Control” tab. Press the “File” button to specify a location and a filename for the captured video. Press the “Rec” button. You may pause at any time and resume by toggling the “Pause” or “Rec/Pause” button. To finish capturing video, press the “Stop” button. Press the “Play” button to view the previously captured video file. Pressing “Play” activates the ActiveMovie Player so that you can view the captured MPEG-1 file. *4.11 MPEG-AVI Feature Description Audio/Video Interleaved (AVI) is a file format created by Microsoft to encapsulate various types of video and audio data. The AVI file contains packets; the AVI packets vary in length and contain Header and Data fields. The Header field is fixed in length and is defined in the AVI standard. The Data field on the other hand, can vary in length. Header information specifies information such as Data types (I-Frame only MPEG-1, JPEG, Audio, etc.) and Data length (10Kbytes). Array VideoONE Recorder has been designed to support AVI. Array has written a Video-For-Windows (VFW) capture and codec drivers that enable the VideoONE MPEG boards to be compatible with any video editing applications, such as Adobe Premiere (referred hereafter as “the application”), as well as a Sound Driver, an Audio Codec and a Mixer Driver for audio support. NOTE: MPEG-AVI features described in this section can be accessed through your editing software’s main menu. Depending on the software, the menus may vary. But in this section, we are using Adobe Premiere’s main menu as examples. *Available in future upgrade 24 4.11.1 Video Capture & Codec Drivers Array VFW Capture Driver During capture, the video editing application, such as Adobe Premiere, will request Frame-Based Header and Audio/Video Data information from the Array VFW capture driver. Then the driver will capture the data using the VideoONE Recorder hardware, fill in the Header and Data buffers, and return the data to the application. The application saves the information (MPEG-1 I-frames) as an AVI file format (.AVI) and stores it on the hard disk. The application communicates with the VideoONE Recorder through the VFW interface. The Array VFW capture driver provides three dialog boxes for the capture application; Video Format, Video Source and Video Display. The Video Format dialog box allows the user to select either RGB or MPEG-1 video format, and SIF or QSIF size format. The picture quality is also controlled from this dialog box through the selection of bit rates: MPEG-1 (I-frame only) Bitrate or Quantizer. MPEG-1 Bitrate allows capture at bitrates as high as 5Mbps. Quantizer allows flexible bitrates but applies a fixed level of quality to the entire picture rather than the selected areas. As a comparison, RGB video format (uncompressed data) bitrate is 60Mbps (7.5 MB/s). Most PCs cannot handle such a high amount of data – that is why compression is used at all. But regardless of the high bitrate, some applications still may want to capture in RGB format. The Video Source dialog box allows the user to choose either NTSC or PAL video standard, and Svideo or Composite video input. It also permits the user to select and modify Brightness, Contrast, Hue and Saturation. The Video Display dialog box will show the entire video parameter setup and selected values in the previous dialog boxes. Array VFW Codec Driver Codec is an abbreviation for compressor/decompressor. The Array VFW Codec is a codec for MPEG-1 data. The compressor converts an RGB frame to an MPEG-1 frame. During decompression (Playback), the Header and Data information (MPEG-1 I-frame) are extracted from the AVI file. The Array VFW Codec enables the user to specify and modify Video Format, Output Options and Compression Method during the editing process. Codec Selection The Video Format dialog box allows the user to specify the Image Size, Image Format and Image Quality. To access this dialog box, (in Premiere) go to: 1. 2. 3. File > Capture > MovieCapture. This enables the Premiere “Movie Capture” video preview window, with a “Record” button. If your camera is connected properly, you will see the video preview in the window. “MovieCapture” menu item will appear in Premiere’s main menu. Go to MovieCapture > Recording Options. 25 4. Click the “Video Format” button. This brings up the “Video Format” dialog box. 5. Specify the desired video Image Size and Image Format. Image Size results depend on the specified video standard: PAL: (SIF) 352 X 288 (QSIF) 176 X 144 NTSC: (SIF) 352 X 240 (QSIF) 176 X 120 6. Click “OK”. After you have recorded an RGB format or MPEG-1 format movie, you are ready to start compressing the movie. The Array MPEG-AVI feature enables you to configure the (audio/video) “Compression Settings” and the “Output Options”. Both of these settings are accessed by going to Premiere’s main menu Make > Make Movie. The “Make Movie” dialog box appears. 26 7. 8. Click the “Compression” button. The “Compression Settings” dialog box appears. It allows you to select how the data (video & audio) will be compressed. Under Compressor Method, select either the “Array MPEG1-IBP” or “Array MPEG1-I”. 27 By selecting the “Array MPEG I” compression method option, your data will be saved as a .AVI file. By clicking on the “Configure” button, the “Quality” dialog box appears – enabling you to change the bitrate or the quantizer settings. By selecting the “Array MPEG IBP” compression method, your data will be saved as a .MPG file. You can also change the compression method configuration by pressing the “Configure” button from the “Make Movie” dialog box. This will bring up the Set MPEG Transcode Value dialog box — which enables you to: • Specify a filename and save it to a location of your choice. • Configure the video bitrate, I-frame bitrate and P-frame bitrate; you may also choose to select the VideoCD (VCD) Whitebook specifications. NOTE: By checking the “Video CD Format” box under Video CD, the video, I-frame and P-frame bit rate configurations are automatically set by the Array VFW Codec. IMPORTANT! If you are using Adobe Premiere, it is required that you also save your MPEG-IBP (.MPG) file as a .AVI file. You can do this in Premiere’s Make Movie dialog box. Note that you can give the .AVI file any arbitrary name; it is only a requirement imposed by Premiere. 7. 8. 28 Click “OK” when you are done. This will bring you back to the “Make Movie” dialog box. Click the “Output Options” button. 9. The “Project Output Options” dialog box appears. It provides you the capability to specify the video and audio output settings. 10. Under Video, select one of the following settings: PAL: (SIF) 352 X 288 (QSIF) 176 X 144 NTSC: (SIF) 352 X 240 (QSIF) 176 X 120 IMPORTANT! You MUST specify the correct video settings before proceeding. In a future software release, these settings will automatically be determined depending on your video standard specifications. 11. 12. 13. 14. For Audio, select the appropriate “Audio Type” from the pull-down menu. If you are using the “MPEG-I” video format, select the “Uncompressed” Audio Type option. If you are using the “MPEG-IBP” video format, select he “Array Audio Codec” Audio Type option. Press “OK” when you are done configuring the necessary settings. This brings you back to the “Make Movie” dialog box. Now that you have configured the settings for Compression and Output Options, you are ready to save your movie. Enter a filename for your movie and specify where you want to save the file. Click “Save” when you are done. 4.11.2. Audio Drivers Other components of Array’s MPEG-AVI feature are the Array Audio Drivers. All Array VideoONE MPEG boards have built-in sound card capabilities, so you do not have to purchase additional hardware. Windows Sound System (WSS) Driver In order to take advantage of the WSS Driver: 1. Go to your computer’s Control Panel folder. 2. Select the Multimedia folder. 3. Under the Audio Playback and Recording tab, select “Array Audio Driver.” NOTE: If you do not have another sound card installed, the WSS Driver will automatically select the Array Audio Driver when you first install the VideoONE Recorder software. You will not need to go through the above steps to enable it. IMPORTANT! If you have a SoundBlaster or Ensonic sound card, make sure to check the “Use preferred devices only” box. Mixer Driver The Array Mixer Driver allows you to adjust the playback (e.g. external PC speaker or headphones/ headsets) and the recording (e.g. microphone or other input devices) mixer controls. There are two ways to access these controls: clicking the speaker/volume icon located on the bottom right corner of your screen or opening the Control Panel folder. One way to access the mixer controls is to click on the speaker/volume icon located on the bottom right corner of your screen. • Double clicking the icon will open the speaker mixer controls, where you can adjust the speaker volume and balance. • To adjust the recording (e.g. microphone input) volume and balance, go to the Options menu and click on Properties. 29 NOTE: Single clicking (clicking the icon once) will allow you to adjust only the speaker volume. You can also switch between recording and playback mixer controls by going to the Options Menu. You can also access the mixer controls through your computer’s Control Panel folder. • Open the Control Panel folder: Windows Start Menu > Settings > Control Panel. • Then open Multimedia. • Go to the Audio tab. • You can adjust the playback (e.g. speaker) and the recording (e.g. microphone) volume and balance from here. The Array AVI to MPEG feature enables the VideoONE Recorder to be compatible with any AVI editing tools, such as Adobe Premiere. With its intuitive user interface, the Array VFW capture and codec drivers provides easy and seamless AVI capture and AVI to MPEG conversion. 30 5.0 FAQ 1. What are the lowest bitrates supported by the VideoONE Communicator? The VideoONE Communicator’s high quality MPEG-1 encoding can meet the low bandwidth requirements for video content over the Internet and Intranet. For H.261 videoconferencing, the lowest bitrate supported is 128Kbps. For MPEG-1 encoding, the lowest bitrate supported is 64Kbps. 2. The other person can hear me, but I can’t hear them. What do I do? • • • • • Check your microphone connections and settings. Also, ask the other person to check theirs as well. Check your volume controls. If you have amplified speakers or a headset, check to make sure that they are connected properly. Check to see if Mute is disabled. Check to see if anyone is using half-duplex. If someone is using half-duplex and they have a sensitive microphone, this may not allow both of you to speak simultaneously. It is recommended that the person running the half-duplex rerun Microsoft’s Audio Tuning Wizard or manually adjusting the microphone’s sensitivity. Check to see if anyone is using full-duplex. If both parties have full-duplex capabilities, it is recommended that you enable it. You can enable it within NetMeeting under Tools > Options > Audio. 3. Do I need a video camera for video conferencing or to use with NetMeeting? No. However, if you do not have a video camera, the person you are calling will not be able to see you. They can only hear you. 4. Do I need a microphone? It depends. If you do not have the Array video camera with the built-in microphone (included with Array model VF300-C), you will need a microphone with line level output. If you have the Array video camera, it has a built-in microphone so you do not need an additional microphone. Refer to Section 2.1.2 - Installing the A/V Equipment for installation details. 5. Do I need to install a sound card? No. The VideoONE Communicator board is designed with a built-in sound card. No additional sound card is needed. If you plan on using your PC for interactive multimedia games/applications, we recommend that you install another sound card that supports those applications. If you cannot hear audio from your sound card, then you need to enable your sound card drivers by going to Control Panel > Multimedia > Audio tab, and select your sound card driver from the Playback “Preferred device” section. 6. Why can’t I hear audio from my sound card? Your sound card drivers may have been disabled during the VideoONE software installation. To enable audio playback using your sound card, go to Control Panel > Multimedia > Audio tab, and select your sound card driver from the Playback “Preferred device” section. If you have the Array model VF300-C which includes a camera, speakers, and headphones, you need to unplug the speaker from the VideoONE Communicator card and plug it in your sound card’s audio out socket. Tip: you can eliminate this process if you connect a mini-stereo RCA male-to-male connector (not included) from the VideoONE Communicator audio out socket to your sound card’s audio in socket. Then connect the speakers to your sound card’s audio out. 7. The person I’m calling is accepting my call but he/she is not there. Can I leave a message? Yes. Open the Chat window and type a message. Then hang up. The person’s Chat window will appear with your message upon returning to his/her computer. The Chat window will not disappear unless he/she closes the NetMeeting application. 8. When sharing applications, does the other person need to have the same applications? No. NetMeeting will share any application, even if the other person does not have the same application – or even if he/she is using a different operating system. 31 6.0 TroubleShooting Tips To prevent any software and hardware incompatibilities, the VideoONE Communicator board has been thoroughly tested in many systems and with many different system configurations. However, it is possible that there may be some systems or configurations that have not been tested. This section provides helpful information and descriptions of common problems, questions and issues reported by VideoONE Communicator and NetMeeting users. If the following troubleshooting tips do not resolve your problem, please contact Array Technical Support (see Contacting Technical Support section below). SOFTWARE No Video Displayed in the VideoONE Overlay Window In order for the VideoONE Overlay window to display video, a recommended graphics card with drivers that support DirectDraw version 3.0 or later (as listed in the “Graphics Card Recommendation” section in this guide) must be installed properly. If a DirectDraw-compatible graphics card and drivers have been installed, verify that the DirectDraw drivers are certified as described in the “Verify DirectX Version and Graphics Card Support” section of this guide. If the drivers are certified and you are still experiencing problems, reduce the refresh rate to 72Hz and the display resolution to 640x480. Graphic cards can often support high refresh rates and resolutions at the expense of disabling video acceleration features, which they would normally support at lower refresh rates and resolutions. Most graphics cards will support the DirectDraw features required by the VideoONE Overlay window at refresh rates of 72Hz and a resolution of 800x600. Set the refresh rate and resolution to a setting that will still support the DirectDraw hardware acceleration features of your graphics card. Contact your graphics card manufacturer for more details on your graphics card feature set. NetMeeting AVICAP32.DLL file cannot start.

USA: UL1950, Europe: EN60950 IEC 950 Appendix D: Desktop Video Camera Operation This desktop video camera is an ergonomically designed product featuring the flexibility of a computer mouse. It allows you to aim the camera in every direction whether hand-held or free-standing, without the difficulty of release-buttons. The camera is equipped with a variable focus lens. The focus can be adjusted manually from a distance of approximately 0.5 cm (macro) to infinity. A microphone is integrated into the camera to give you live audio. Power Turn on the power switch. The green LED on the front of the camera indicates that the power is on. When the LED is blinking there is something wrong with the functionality of the camera. Please contact your dealer. When the power is switched to “stand-by” the camera is functionally switched off, so both video and audio signals are disabled. Contrast By means of the contrast control the picture can be adjusted to your personal preference. Press this button in order to activate the loop. The brightness of your picture changes. When you stop pressing the button, the actual setting is selected. In case the Flickerless (FL) is switched “on” the function of the contrast button is limited. When the camera is switched off and on again, the contrast is set to default mode. Back light compensation (BLC) Switch the BLC-switch to “on” to improve the image-quality when you have a scene where the background has a high illumination level (for example when you sit in front of a window). White balance (WB) When the WB-switch is in the Fixed (freeze) mode, the automatic white balance control is switched off. The actual color setting is stored and is not influenced by controls of the camera. It is recommended to put the white balance in Fixed mode when you have a colored scene and stable lighting conditions (preferable not to be used in fluorescent light environment). The procedure to obtain a perfect color reproduction is as follows: Put the WB switch in Auto mode, hold a white paper in front of the camera and switch over after a few seconds from Auto to Fixed mode. Now the color setting remains even when you switch the camera’s power off. When light conditions change, it is recommended to put the WB in Auto mode. Flickerless (FL) In an environment with fluorescent light, a slightly noticeable flickering and coloring of the picture may occur. In this situation, it is recommended to put the FL-switch “on”. The shutter speed is fixed to flickerless. The maximum illumination level of the camera is limited in this situation. Using this feature, the performance of the camera in an office environment can highly be improved. It also allows you to use a PAL camera in 60 Hz or a NTSC camera in 50 Hz environment without artifacts. Focus range It is possible to focus on extreme short distance (approx. 0.50 cm) by rotating the lens in the desired direction. If you want to have a sharp image within a wide range, aim the camera at an object on a distance of more than 5 meters and rotate the lens until you get a sharp image. In this case, the camera is in focus from 0.6 meters till infinity. Sound The microphone is located at the front of the camera. Live audio is available at the white cinch connector. 39 Appendix E: Speakers* & Headphones* Specifications Multimedia Ampliefied Speakers • • • • Built-in amplifier 14 Watts Single Volume Control Headphone Jack Magnetically Shielded Design • • • • • • • • • • Drive Unit: 2" x 4" full range Output Power: 14 Watts P.M.P.O.: 80 Watts Frequency Response: 20Hz to 20KHz Input Sensitivity: 1000mV S/N Ratio: 40dB Impedance: 4 ohm Power Supply: AC/DC 9V adaptor included Controls: Power Switch, Volume Dimensions (W x H x D): 3" x 7.5" x 5" Headphones • • • • • • • • Designed for use with personal computers L-Shaped stereo mini plug for PC connection PC-color coordinated Lightweight open-air type headphones Large 23mm open-air driver units Wide molded headband for added comfort High quality sound reproduction 1.25 oz (36g), without cord * Speakers and headphones are only available with Array model VF300-C. 40 Appendix F: VideoONE Software Development Kit (SDK) In addition to the standard software application, the VideoONE Software Development Kit (VSDK) is available for those who would like to develop their own applications to perform real-time MPEG-1 capture and compression.
