This document introduces guidelines for successfully configuring Luminato in various applications. The document is not intended to cover all details in every possible Luminato application, but the most typical use cases should be described. This document should give all relevant info to realise proper configuration for live service processing. The document has following structure: 1. Initial setup - enable management access 2. System level setup - adjust system level settings to create compatibility with other devices and Luminato chassis in same network 3. Interface configurations - enable all physical interfaces ready for video/audio payload transmission 4. Service configurations - service acquisition and descrambling - UDP/IP streaming (SPTS and MPTS) - DVB stream processing (component filtering, SIDPID remapping etc,) - multiplexing - PSI/SI table generation This document is mainly done to be used use with release 3.6.x. The screenshots may differ from version to version slightly, but functionality should be equivalent. This configuration guide introduces mainly procedures using WEBUI, but there is also configuration guides for some procedures using CLI (Command Line Interface). It is recommended to use Mozilla Firefox 3.0 or newer. 6(68) CONFIGURATION GUIDE April 21, 2011 2 CONFIGURATION STEPS Prior to configuration process, it is assumed that operator has removed Luminato from its delivery box, done rack instalment and all relevant cable connections. Also all system level parameters (IP address, frequencies etc,) should be easily available for configuration process. Full configuration has following steps: 1.) Initial setup – create management access to Luminato - management IP address - chassis hostname - user accounts 2.) System Level Configuration - administrative settings (time reference, SNMP, event logs, syslog) - Payload network IP addresses - SID and PID ranges 3.) Interface Configuration - GE1 and GE2 port setting - Receiver tuning - QAM and COFDM modulation output parameters - Conditional Access module configuration 4.) Service Configurations - service reception and descrambling - service routing to multiplexer - SI table insertion Next chapters go through each topic and give guidance to create full functional headend for either IP streaming and/or cable delivery. 7(68) CONFIGURATION GUIDE April 21, 2011 3 3.1 INITIAL SETUP Management IP address The first step is to create management access through MGMT1 port. Factory default management IP address is 192.168.0.100 User can change management IP address two ways: 1.) Terminal connection method Refer to Luminato Quick Start Manual for details. Follow these steps: - install USB serial cable driver to PC - connect USB cable - create terminal session through serial USB - login as: admin; password: admin - use CLI command to change management IP address, mask and gateway Luminato1(configure)# ip address mgmt1 192.168.0.100 255.255.255.0 192.168.0.254 2.) HTTP browser method - Luminato factory default management IP is 192.168.0.100 - NOTE: PC must be in same subnet to establish proper connection to Luminato - open Internet Explorer 7 or 8 or newer or Mozilla Firefox 3.0 or newer - Choose Network-page from Administration-menu - open Edit Management Interfaces-link for IP address configuration - enter new management IP address, mask and default gateway and accept changes NOTE: Connection is lost to Luminato after accepting new management IP address. Change PC IP address to same subnet. Refer to SYSTEM LEVEL CONFIGURATION chapter to assign IP address for MGMT2 port in chapter 4.1.1. 3.2 Account Management Luminato has by default four user groups: 1.) admin, factory default username: admin and password: admin. 2.) oper, factory default username: oper and password: oper. 3.) install, no usernames by default. 4.) monitor, factory default username: guest and password: guest. Admin group has full access to all configurable parameters including administrative settings. Install group has full access to all configurable parameters except administrative settings: cannot create/change admin-users and cannot edit provider lock-up settings (aka network lock). Oper group access is limited only to configuration of services and view of network settings. Oper group has no access to administrative settings or procedures like software upgrade. Monitor group has read-only access for monitoring purposes only. Can not change any settings. 8(68) CONFIGURATION GUIDE April 21, 2011 User may change password of default user accounts or create new accounts. 9(68) CONFIGURATION GUIDE April 21, 2011 4 SYSTEM LEVEL CONFIGURATION 4.1 Administrative settings This part of configuration includes administrative settings i.e. management IP address, chassis host name, payload ports (GE1 and GE2), internal clock synchronisation and sub module settings including video/audio payload IP address and SID and PID ranges for automatic allocation. These parameters should be set before any configuration of interfaces and services are done. 4.1.1 Management IP address for MGMT1 and MGMT2 ports Luminato has two 10/100Base-T ports for management purposes, which are labelled MGMT1 and MGMT2. These ports are located in the power supply / interface module. Figure 1 Power Supply / Interface module: MGMT1 and MGMT2 ports The management ports can operate in two modes called Common network and Separate networks: Common network means that both management ports are working as switched ports. Therefore one IP address is assigned for Luminato management and it is accessible through both physical ports MGMT1 and MGMT2. This mode can be used like two-port switch. Separate networks mode means that both physical ports MGMT1 and MGMT2 have their own IP addresses. This mode is useful in creating separate networks for general management and Conditional Access. The second application is to create two totally separated management networks. NOTE: Separate networks mode doesn’t have routing capability between MGMT1 and MGMT2 ports. CONFIGURATION GUIDE April 21, 2011 4.1.1.1 Configuring management ports (MGMT1 and MGMT2) in WEBUI The followed procedure explains management IP settings using WEB user interface. NOTE: User must login as administrator to able to change management IP address settings. Procedure steps are: 1.) Define management ports operating mode: common or separated 2.) Define management ip address parameters for ports Choose Network-page from Administration-menu Click Edit Management Interfaces –link Figure 2 Edit management port IP address, Netmask and Gateway settings. Choose Port mode from dropdown list. Figure 3 Management ports operating mode selection Common network mode has only one management IP address for configuration. Separate networks mode enables two management IP addresses for configuration. CONFIGURATION GUIDE April 21, 2011 NOTE: Older chassis may not have Separate networks item available in dropdown list. The reason is that the second MAC address for MGMT2 interface is not set. This can be fixed with following procedure: 1.) Open CLI session to Luminato using proper terminal software. 2.) Login as Administrator (for example user account: admin password: admin) 3.) Execute following commands: Luminato# configure Luminato (config)# interface mgmt1 Luminato (interface-mgmt1)# upgrade-management-mac-address COMMIT Programming management MAC2: 00:90:50:03:DD:16 New management MAC2 set successfully. Please reboot to activate. Luminato (interface-mgmt1)# exit The 2nd MAC address is now set and Luminato is ready for Separate networks configuration. Enter configuration for MGMT1 and MGMT2 ports: Figure 4 Management ports settings; separate networks selected for MGMT1 and MGMT2 NOTE: If you changed IP address while doing management IP address configuration, connection to Luminato is lost. You must make new login using new management IP address. 1.) Select from DHCP dropdown: - No => Static IP address settings are used. Follow steps 2 ... 7 to enter all static parameters. - Yes => IP address settings are assigned by DHCP server. Jump to step 7. NOTE: It is recommended to use static IP address settings. 2.) Enter IP addresses 3.) Enter Netmasks 4.) Enter Gateway addresses 12(68) CONFIGURATION GUIDE April 21, 2011 5.) Choose Default Gateway (column Default) 6.) Adjust MTU (Maximum Transmission Unit), if necessary. Default value is 1500. 7.) Press Save-button to accept settings. Luminato has new ip address for MGMT1 and MGMT2 ports. Use new IP address to login into Luminato. 13(68) CONFIGURATION GUIDE April 21, 2011 4.1.1.2 Configuring management ports (MGMT1 and MGMT2) in CLI The next procedure introduces configuration steps for management IP settings using CLI. NOTE: User must login as administrator to able to change management IP address settings. Open CLI session to Luminato using terminal software (telnet or SSH protocol) Login as Administrator (for example user account: admin password: admin) The followed commands set management IP address, netmask and gateway address for MGMT1 port. HINT: Entering ? –mark after command gives hint for next command options Execute followed commands for MGMT1 ip settings: Luminato(configure)# ip address mgmt1 192.168.111.231 255.255.255.0 192.168.111.254 The followed command sets management ip setting for MGMT2 port. Luminato(configure)# ip address mgmt2 172.16.1.124 255.255.255.0 172.16.1.254 The next step is to define which management port is used as default gateway. Luminato(configure)# ip default mgmt1 To verify management ip settings, use show-command: Luminato(configure)# show ip !!! Management-port-mode : separate Management 1 : Status DHCP IP address Network mask Gateway MAC address MTU TX bytes RX bytes : : : : : : : : : active disabled 192.168.111.231 255.255.255.0 192.168.111.254 00:90:50:03:12:6a 1500 119009423 110556709 Management 2 : Status DHCP IP address Network mask Gateway MAC address MTU TX bytes RX bytes : : : : : : : : : active disabled 172.16.1.124 255.255.255.0 00:90:50:03:dc:6a 1500 95678855 101635456 IP routing table Destination Gateway 172.16.1.0 0.0.0.0 192.168.111.0 0.0.0.0 default 192.168.111.254 Luminato(configure)# NetMask 255.255.255.0 255.255.255.0 * Interface MGMT 2 MGMT 1 MGMT 1 State Volatile55 Volatile Volatile 14(68) CONFIGURATION GUIDE April 21, 2011 4.1.2 Host name Chassis host name can be changed from Administration/Network-page. Click Edit – link in Hostname. Figure 5 Hostname edit Enter descriptive host name. NOTE: Please note that hostname can neither have special characters nor spaces. CLI-command for hostname configuration: Luminato(configure)# hostname Luminato1 CONFIGURATION GUIDE April 21, 2011 4.2 4.2.1 Gigabit Ethernet GE1 and GE2 ports configuration SFP-module types Luminato GE1 and GE2 ports supports various types of electrical and fibre SFP modules. It is recommended always to use SFP modules that are tested with Luminato. Teleste supplies SFP modules that have order codes: LSFP-A, LSFP-B … LSFP-G For SFP module details, refer to Luminato Chassis Specification document. NOTE: GE1 and GE2 ports have two user selectable modes for SFP-modules: 1. Fibre Compatible - factory default - this using SERDES-type interface between SFP-module and host - supports fibre SFP-modules - supports LSFP-G electrical 1000Base-T SFP-module 2. Electrical only - this uses SGMII-type interface between SFP-module and host - supports LSFP-A electrical 10/100/1000-T SPF-module - NOTE: This module operates in 1000Base-T speed with current software release. Future release will add support to 100Base-T. When electrical interface is used, it is recommended to order LSFP-G electrical 1000Base-T SFP module, because it works immediately with factory default settings and configuration is not needed. The module type can be read from the sticker on the SFP module. HINT: If you find out that Luminato is not streaming even though you think of having done proper configuration, and user interface reports streaming bitrates, it is quite typical that SFP-module mode has wrong setting. Figure 6 Upper: LSFP-A electrical 10/100/1000Base-T SFP-module, Lower: LSFP-G electrical 1000Base-T SFP-module. 16(68) CONFIGURATION GUIDE April 21, 2011 4.2.2 GE1 and GE2 port operating modes: Common and Separated networks Luminato has flexibility to configure GE1 and GE2 ports behaviour. User can select: 1.) Common network (=mirrored), where traffic exists in both ports. An ip streamer traffic is copied to both ports as exact copy. An ip input can receive from both ports. NOTE: User must take care that both ports are not connected to same switch, because unexpected loop can appear. The connected networks must be totally separated. 2.) Separated networks, where ip streamers or ip inputs can be assigned either GE1 or GE2 ports. Total traffic can now exceed 1 gigabit, because both ports are used separately. The next procedure defines: 1.) Payload ports operating mode: a) common (=mirrored) b) separated 2.) SFP-module interface operating mode: a) Fibre compatible b) Electrical only Open Administration/Network-page and select Payload-tab Figure 7 Payload interface and SFP configurations Click Edit Payload Interfaces –link to change Payload port mode and SFPmodule mode. 1.) Choose from dropdown GE1 and GE2 port operation mode: - Common ( = mirrored ports ) - Separated networks. 2.) Adjust mode that matches installed SPF module. Figure 8 Choose from drop down list used SFP-module type. Note: There are two different electrical modules! Choose Port mode: Common networks = mirrored, Separate networks CONFIGURATION GUIDE April 21, 2011 4.2.3 External I/O Figure 1b Power Supply / Interface module: External I/O pins Luminato external ex multipurpose I/O-pins can be used for several everal predefined applications applications. Note: when 1+1 backup is selected other application modes cannot be used. used Make sure that ‘standalone’-role role is selected from Administration -> 1+1 Backup before using any other External I/O application modes than 1+1 backup backup. When ‘standalone’-role ‘standalone’ role is selected the device can be used for other EXT EXT-IOfunctions from PSU-module PSU config on Main page: Note also that 1+1 backup requires a separate license, but the other functions can be activated without any license-keys. license 4.2.3.1 1+1 backup When 1+1 backup –application is in use it reserves both of the EXT1 and EXT2 I/O pins. Prior to configuring the devices make sure that both LCH chassis’s have 1+1 backup licenses. CONFIGURATION GUIDE April 21, 2011 Two identical devices (ie. “main” and “spare”) are connected with LACCA – cables together. together The spare device has identical configuration as the main-unit with the exception tthat all its output ports are shut down. The spare unit is constantly monitoring the predefined triggers from the main unit and in case of failure it does the fail-over switching. The main applications for Luminato 1+1 backup are: • Hardware failure redundancy • Signal ignal redundancy (in case of a signal loss situation) In signal redundancy case both of the devices have same input signals, but from different independent sources. Fail over switching is activated if the input or service whic which is configured as critical is lost. For more details about how to configure 1+1 backup please refer to Luminato_1+1_backup_configuration_guide.pdf Luminato_1+1_backup_configuration_guide.pdf. 4.2.3.2 Intrusion alert In intrusion alert application the external switch detects the act of intrusion – opening a door or window for example. The alarm is triggered when the closed closedcircuit system is opened. For example a magnetic sensor in a closed circuit consists of a few simple components. The components for the most basic design are: • 2--wire cable with 2-pin header connectors • A magnet lined up with a switch Connect the closed circuit to ext1- or ext2 -connector and activate intrusion alert- functionality from EDIT EXT MODE SETTINGS in PSU --module config. Press save. When the loop opens, opens Luminato turns on the alarm state in main page, writes the details to syslog and sends snmp-traps. Manual intervention is required to clear the alarm state back to normal normal. 4.2.3.3 Backup power alarm When the backup power supply LPS-F or LPS-G is used it is recommended to use ext1- or ext2 –connector to activate alarm in case of backup power failure. CONFIGURATION GUIDE April 21, 2011 “Backup power supply failure” –message is shown in main page, details are written to syslog and the snmp trap will be sent. Alarm state is cleared when the backup power clears the external I/O-pin. 4.2.3.4 Customizable Input / Output modes It is also possible to build own applications for the two external input/output – pins (ext1,ext2). For example to monitor external devices and get notified/alerted about the state changes and/or it is possible to control external devices manually from Luminato’s user-interface. Make sure that ‘standalone’-role is selected from Administration -> 1+1 Backup. Choose EXT MODE SETTINGS in PSU -module config on Main page. The supported options for the user input –mode are: • Severity levels { emergency, alert, critical, error, warning, notice, informational } • Signal polarity {up, down, any change} • Input signal status is shown and details written to syslog. Also snmp trap is sent if severity setting is emergency, alert or critical. • Signal status is automatically cleared after the state has been clear for 10 seconds. And for the user output –mode: • Set output {down, up} • “Toggle”-button for changing the output state 4.2.3.5 EXT-IO technical details 4.2.4 Chassis internal clock Luminato internal clock is used to event logging time stamps and TDT/TOTtables, when created by Luminato. User can synchronise Luminato internal clock to external NTP server or use current time from browser. Additionally internal clock can be synchronised to incoming DVB stream. User must select, which interface is used for clock reference. CONFIGURATION GUIDE April 21, 2011 Figure 9 Luminato internal clock configuration Internal Clock configuration Internal clock can be adjusted from Administration/Services--page. 1.) Click Edit Time Settings –link to enter time configuration 2.) Choose source of time from dropdown list: a.) Real time clock –selection selection allows user to synchronise internal clock to management computer’s browser time. b.) External NTP server –selection selection allows user to synchronise internal clock to external device that gives accurate urate time through NTP protocol. Upto three NTP servers can be defined. c.) DVB stream –selection selection allows user to synchronise internal clock with incoming DVB stream. Luminato can use incoming TDT/TOT table information for time synchronisation. The input connec connector must be specified. Choose from DVB input –dropdown dropdown list the input that is used for clock synchronisation. 3.) Adjust time zone according to installation location. 4.) Press OK-button to accept changes. NOTE: Luminato does do not have battery backed up clock so actual ctual time is lost if power is shutdown. Therefore it is recommended to use NTP server for clock synchronisation. CONFIGURATION GUIDE April 21, 2011 4.3 Sub module System Settings All Luminato sub modules have system level settings. Sub modules have IP address for payload. It is either source port for UPD/IP streaming or destination address for unicast UDP/IP stream reception. Typically, these IP addresses must be in same subnet with other devices streaming or listening UDP/IP video. If “separate networks” mode is used for GE1 and GE2 then there are two IP address in a module to assign to GE1 and GE2 respectively. Luminato has internal intelligence for automatically remapping SID (Service ID) and PID (Packet ID) according to configured ranges. This feature enables creation of SID and PID plan having unique values for each service. Therefore further processing in system is easier and there are no SID and PID conflicts. These parameters can be accessed through Configuration/Modules-page. Select Slot-tab for the module to be configured. Repeat sub module system settings for all modules installed to system. Figure 10 System level settings for submodules 22(68) CONFIGURATION GUIDE April 21, 2011 The configuration section has following parameters: 4.3.1 Video/AudioPayload IP address, Netmask and Gateway: This is used as source IP address for streaming from the module under configuration. This is also input interface IP address for QAM and COFDM modulator cards and ASI output modules. These IP addresses are shown through GE1 and GE2 interfaces. Netmask and Gateway settings are needed for unicast streaming. IP addresses for each module typically must be in same subnet. Typical IP addresses are allocated in sequence: Slot 1: GE1: 192.168.2.11; GE2: 192.168.3.11 Slot 2: GE1: 192.168.2.12; GE2: 192.168.3.12 Slot 3: GE1: 192.168.2.13; GE2: 192.168.3.13 Slot 4: GE1: 192.168.2.14; GE2: 192.168.3.14 Slot 5: GE1: 192.168.2.15; GE2: 192.168.3.15 Slot 6: GE1: 192.168.2.16; GE2: 192.168.3.16 Netmask syntax is 255.255.255.0. Gateway is used for router address in same subset. These settings can be entered either Modules-pages or Adminstration/networkpages. 4.3.2 SID step size, SID and PID ranges These parameters are used in automatic SID and PID allocation for output streams to create unique SID for every service and unique PID for every component. Factory default ranges guarantee that there are no overlapping PID values in one chassis configuration. NOTE: If a system consists of multiple chassis, then these ranges have to be adjusted accordingly to have unique ranges over system. Sum of (SID range + SID step size high limit) should be kept well below null PID (8191) for automatic SID and PID allocation work as designed. HINT: It is recommended to do SID and PID remapping already in receiver modules to create proper SID and PID allocation for operator’s system. The output modules can then be used in SERVICE PASSTHROUGH –mode, where SID and PID values are not changed. The next chapters explain automatic SID and PID allocation options in detail. 23(68) CONFIGURATION GUIDE April 21, 2011 Figure 11 SID step size, SID and PID range settings on module page. 4.3.2.1 Automatic SID allocation Automatic SID allocation is effective only with selective SERVICES configuration. SERVICE PASSTHROUGH configuration keeps SID unchanged. WEB UI opens SERVICES-sections automatically to steer user to use this configuration method in input modules (i.e. satellite and terrestrial receivers and ASI input modules). Figure 12 Automatic SID allocation based on SID range and SID step size is effective only using SERVICES ( ) configuration. Incoming SID 200 is remapped to 5560 according to SID range. PID allocation mode is set to SID mode. The output SID depends on slot number and list of available SIDs within the module. New SID values are allocated by SID step size (default step size is 20 i.e. 40, 60, 80 ...) from lower SID range. When lower range is fully used, SID values are allocated from upper SID range by SID step 1. 4.3.2.2 Automatic PID allocation Unique output PID values for each component are generated automatically, if PID allocation mode is set to SID mode. Output PID values are calculated as follows: CONFIGURATION GUIDE April 21, 2011 1. PMT_PID = SID 2. Video_PID = SID+1. 3. Teletext PIDs = SID+2 4. Subtitle PIDs = SID+3 5. Audio PIDs = SID+4 and SID+5 6. Other components = SID+6 to SID+9 Figure 13 Automatic PID remapping, when PID allocation mode is set SID mode PID allocation mode has also other choices: Input follow mode: keeps incoming PID values Component mode: uses same PID mapping rule as SID mode, but starting PID can be defined by Start PID on SERVICE ADVANCED SETTINGS. Note: SID step size defines maximum amount of components-1 that can be included to a service without causing a need to use PID range. If a service has more components than SID step size defines, then next component PID value is taken from PID range in sequence. “PID remapped”-notification is given in user interface to indicate that some PIDs are allocated to PID range. 4.3.2.3 Manually set output SID and PID values Automatically generated output SID values can be changed manually. Userdefined output SID value overrides automatic SID allocation rules. Manually entered output SID value is surrounded with orange box for indication of a user set value. Output PID value can set manually using component filter or PID remapping functionality, which are explained later in this manual. 4.3.3 Warning timeouts Sub modules have warning timeout settings. Figure 14 PID timeout and warning timeout CONFIGURATION GUIDE April 21, 2011 PID timeout sets sensitivity of PID missing warning by defining time (in seconds) a PID needs to be missing before PID missing warning appears. PID monitoring must be set separately in monitoring page. TDT/TOT tables are typically every 30 seconds; therefore this setting must be more than TDT/TOT interval to avoid unnecessary warnings. Warning timeout Time limit to a service or input bitrate has to be zero, before warning is raised. 26(68) CONFIGURATION GUIDE April 21, 2011 5 INTERFACE CONFIGURATION This chapter explains setup of all physical interfaces for stream routings. After this chapter configuration modules are ready for service configurations. Configuration guides for video/audio gigabit Ethernet GE1 and GE2 ports are in chapter 4.3.1 All Luminato sub module physical interfaces can be found from menu Configuration/MODULES-page. The page has TAB view for 6 slots. Activate module slot TAB for interface configuration. Luminato input modules’ i.e. receivers’ configuration guides start from chapter 5.1 • LRS-A dual DVB-S/S2 receiver with two CA-module slots module • LRS-B quad DVB-S/S2 receiver module • LRT-A dual DVB-T receiver with two CA-module slots module • LAS-A quad DVB-ASI inputs module Luminato output modules’ (multiplexers, modulators) configuration starts from chapter • LQM-A quad QAM modulator • LQM-B quad QAM modulator • LCM-A dual/quad COFDM modulator 27(68) CONFIGURATION GUIDE April 21, 2011 5.2 Satellite Receivers Figure 15 LRS-A dual DVB-S/S2 receiver with two CA-module slots Figure 16 LRS-B quad DVB-S/S2 receiver Open Configure/Modules-page and choose correct Slot for satellite receiver. Following picture shows typical view of configured dual satellite receive. Figure 17 Dual satellite receiver module information, system level configuration and front end configuration and status information 5.2.1 DVB-S/DVB-S2 Module properties and system level setup The left side shows module properties for module identification (PROPERTIES). The CONFIGURATION section has system level configuration parameters. These parameters are explained in system level configuration in chapter 0. 28(68) CONFIGURATION GUIDE April 21, 2011 5.2.2 DVB-S/DVB-S2 Reception status The right side has quick view for reception conditions of two input interfaces. The Signal bar indicates relative input signal level within receiver’s acceptable input level range. Also reception lock status is shown For best reception conditions bar should be close to the middle of the shown range. Full white bar means that input level is low and it may potentially cause signal drop. To fix this user should make dish realignment or add external amplifier to boost input signal level. Full green bar indicates that input level is in its high limit which may cause receiver input to overload. To fix this add 10 dB attenuator to the signal path before the receiver. FEC field shows demodulator lock status (green = lock) and code rate used by the Viterbi code. The estimated Signal-to-Noise Ratio value can be used to analyse signal reception quality and changes in reception conditions. The frequency row shows configured satellite reception frequency. The frequency offset value shows difference between actual and configured frequency. Typical frequency offset values are within +- 2000000 Hz. This offset is caused by LNB local oscillator drifting. Offset should not be more than half of symbol rate. Too big value may indicate locking to wrong transponder. TS bitrate shows received MPTS speed. SR shows configured symbol rate. Received transport stream is error free, if BER remains in 0.000E+00. This can be achieved, if VBER is below 1.000E-03. If BER>0, then received stream has bit errors, which may be visible in picture or measurement device. 5.2.3 DVB-S/DVB-S2 Input Interface configuration To change parameters select configure-link for interface to open the following configuration page.

Refer to http://www.lyngsat.com/ or http://www.satcodx.com/ or http://en.kingofsat.net/ or similar satellite directory site. 5. Enter LNB frequency. Typically this is 9750 or 10600. HINT: SAT freq – LNB freq must be in range 950 …. 2150 MHz. 6. Enter Symbol Rate (refer to satellite directory) 7. Modulation and Spectral inversion are detected automatically in AUTO mode. AUTO mode is normally recommended, but if reception conditions vary, it might be better to choose the fixed value to avoid automatic discovery of these parameters. Choose fixed values from dropdown menus. 8. Frequency offset limit setting is for acceptable frequency tracking range. If frequency tracking is out of range, warning is generated. HINT: use value from range 2000000 Hz … Symbol rate divide by 2. LNB local oscillator may drift, because of temperature changes and aging. Offset value should be set in a way that allows natural drift of LNB local oscillator, but creates warning if receiver tries to lock to adjacent transponder. 9. Enter LNB power feed parameters, if LNB powering is supplied from this receiver HINT: If universal LNB is used, then typically voltages 13/18 V are to adjust polarisation V/H accordingly. The 22 kHz tone is typically used for band selection: disabled = low band (10700 …11900 MHz, LNB frequency is 9750 MHz) and enabled = high band (11550 … 12750 MHz, LNB frequency is 10600 MHz). 10. LNB current setting has adjustable limit to detect LNB failure (open or short circuit). Enter limit values for low current and high current boxes. Entered values create warning limits.

The module is intended to use in DVB-T over Coax application. The amount of modulators depends on used modulation mode: • 2K mode supports up to 4 modulators • 8K mode supports up to 2 modulators. Typically DVB-T receivers support both modes, therefore 2K mode can be used to maximise modulators in module. For compatibility purpose 8K mode is also configurable, but with reduced amount of modulators. To maximise available bitrate, protective features of DVB-T modulation can be set to minimum in coaxial access network. However DVB-T modulation offers more robust transmission over coax than comparable QAM modulation. The maximum bitrate capacity is achieved with following settings: Guard interval: 1/32. Modulation: 64-QAM. FEC code rate: 7/8 These settings create maximum multiplexing rate 31,688Mb/s. In COFDM modulator module four modulators in adjacent channels are sharing the same up converter. When first modulator output frequency is set, the next modulator frequencies follow the first one in steps defined as channel spacing (offset). Each modulator can be disabled separately. The module has multiplex IP streaming feature. This makes possible to send copy of COFDM output to IP networks for other modulators module in other location or monitoring purpose.

CONFIGURATION GUIDE April 21, 2011 6 DESCRAMBLING MODULE SETUP The next phase is to install descrambling modules and setup CA-module configuration. Luminato supports CA-modules that comply with DVB-CI EN50221 standard. Teleste has tested Luminato against Aston and Smit manufactured CAmodules. Figure 36 CA-module view: module identication, failure management, module assignments with interfaces, service descrambling status The upper CA-slot in receiver module (LRS-C, LRT-A) is named as A and the lower CA-slot is B. A B Figure 37 CA-module slot naming: A and B 6.1 CA-module identification The top part of page has detailed module identification information. Aston and Smit manufactured modules are tested with Luminato. Teleste actively follows these vendor’s developments for CA-modules. Luminato CA-module interface is designed according to DVB standard. Therefore all CA-modules that comply with DVB-standards should work without issues, but practically all modules are CONFIGURATION GUIDE April 21, 2011 not strictly following the standards. It is recommended to use Aston or Smit modules to avoid problems in descrambling. 6.1.1 Accessing CA-module menu CA Menu –button opens CA-module MMI-interface. Each module vendor has unique CA-module view. User may check subscription status for services by selecting appropriate menu item. The CA-module detailed information is also typically available through MMI. Typically some menu items bring visible module hardware and software versions, which are essential information when reporting issues with CAmodules. 6.2 CA module routings ROUTING section has table matrix to connect CA-modules to selected RF inputs. Typical setup is to assign one module per RF input, but in order to extend descrambling capacity both CA-module slots can be assigned to one RF input. . At the same time the second input can be used for receiving FTA services. Another reason for cascading two modules could be use of CAmodules capable of descrambling different CA systems in the received multiplex. 6.3 CA-module failure actions Failure Action section is to adjust CI-interface operations, if CA-module fails descrambling. For high quality and mature CA-modules all actions should be disabled by default. If descrambling fails, user can try to revert descrambling using automatic failure action tools. Failure action settings define what actions Luminato takes when its internal descrambling monitoring function reports descrambling failure. Refresh PMT tries configured times to reconfigure module for descrambling by re-sending CA_PMT table to CA-module. If Refresh PMT doesn’t fix descrambling failure after configured trials, the next level of action is activated: Reset CAM executes restart of CA-module. This method is tried as many times as configured. If CAM reset doesn’t fix descrambling fail after configured trials the next level of action is activated: Reset module executes receiver module reboot. Timeout parameter is used to define period for descrambling monitoring to wait until proceeding to next failure action. Figure 38 CA-module failure action configuration 49(68) CONFIGURATION GUIDE April 21, 2011 Typical configuration could be to set 1 to Refresh PMT and Reset CAM and disable Reset Module. 6.4 Services descrambling status SERVICES section on CA-modules page shows descrambling status for each service and its components. User may expand service by clicking the plus sign next to each input to see component level descrambling status. Service descrambling is configured on Processing-page. More detailed information for service or its component descrambling configuration can be found in chapter 7.2.4 Service Descrambling Figure 39 Descrambling status view for services and its components 50(68) CONFIGURATION GUIDE April 21, 2011 51(68) CONFIGURATION GUIDE April 21, 2011 7 SERVICE CONFIGURATION Service configuration is done in two parts: a) Service streaming to multicast IP and b) multicast IP stream receiving to multiplexing. Destination Multicast IP address and port are used create interconnection between module streaming outputs and QAM module IP inputs. The first step is to create Service streaming to multicast IP. The followed chapters show step by step configurations to create SPTS streaming for a service. This process should be repeated for each service. After service streaming is finished, and then the second phase makes connection from IP domain to multiplex. This is described after Service streaming chapters. 7.1 Stream processing and routing strategies User can choose the strategy how to stream routings are done. 7.1.1 SPTS IP streaming SPTS IP streaming (having one service per output stream) is typically used in IPTV configurations, where it is essential to have only one service per multicast IP stream. This method can be used also in cable TV system to maximise flexibility to pick up and organise multiplexing freely. This allows also create localised channel line ups at remote headends. Demultiplexing license must be enabled to allow multiple IP streamer outputs per input connector and then create SPTS IP streaming for each service. 7.1.2 MPTS IP steaming MPTS IP streaming is optimum for configurations, where multiple services are chosen from incoming transport stream and passed through to multiplexing side i.e. transmodulation applications. This method minimise needed stream routings between input and output modules. The second purpose for MPTS IP streaming is to maintain received statistical multiplexing through to system. Demultiplexing might be not needed in this scenario, because all services are streamed within one IP output. Luminato support both SPTS and MPTS IP streaming freely. Also stream copies can be created (demultiplexing licences must be active). 52(68) CONFIGURATION GUIDE April 21, 2011 7.1.3 SERVICES PASSTHROUGH and SERVICES configuration Service configuration can be done two ways: SERVICES PASSTHROUGH and SERVICES. Figure 40 SERVICE PASSTHROUGH and SERVICES configuration section in PROCESSINGpage SERVICE PASSTHROUGH configuration method lets pass through all components that are referred in PAT and PMT tables. All ghost PIDs and SI PIDs are filtered. Service ID (SID) remains original and internal rules for SID remapping is not used. Original PID values can be kept using PID allocation mode: “Input follow mode”. Advanced stream filters, descrambling and scrambling configuration are not available in this configuration method. This method is intended to act like pass through for services. SERVICES configuration method includes advanced stream processing features: Component/PID filters, Descrambling, Scrambling, Service Advanced Settings. This method also uses internal SID and PID remapping rules (PID allocation mode should be: “SID mode”. SERVICES mode is typically used in receiver modules to adjust channel line up properly to operator’s network. SERVICE PASSTHROUGH mode is recommended to use in output modules to avoid service specific configurations. All service changes are reflected automatically from incoming streams to output. Both methods can be mixed in same stream configuration. But be careful to configure a service only one time using SERVICES PASSTHROUGH or SERVICES method. Otherwise result may be unexpected. For example if incoming MPTS is pass through using SERVICE PASSTHROUGH, but user want to scramble one service from MPTS. The must be filtered (deselect) from SERVICES PASSTHROUGH section and then added to SERVICES section for scrambling configuration. SI PIDs can be routed from input to output using PID FILTER –section. PID filter can be used also selectively pass through ghost PIDs. Full pass-through can simulated using SERVICE PASSTHROUGH for all referred components and then add PID filters for SI PIDs (16, 17, 18, 20). NOTE: All unreferred PIDs are removed. 7.1.4 Elementary stream and PID filtering Typically it should be removed all unwanted components and PIDs already in input modules (i.e. receivers and ASI input) to save bandwidth in operators network and also to have safe streaming not having unknown components. Therefore stream and PIDs filters should be configured into input modules. 7.1.5 Service ID (SID) and PID remapping To have unique PID values in operators system, they should be remapped in input modules. Luminato has flexible methods to do remapping. By default Luminato does automatic SID and PID remapping based configured SID and PID ranges in receiver modules. This way system does not have PID clashing in multiplexing side. However if for some reason same PID is coming from two inputs to multiplex, Luminato can do automatic PID remapping to avoid PID clashing. Warning is generate from this occasion. 53(68) CONFIGURATION GUIDE April 21, 2011 7.1.6 SERVICE PASSTHROUGH in multiplexing and output module configuration To minimise need for reconfiguration in multiplexing (QAM modulator or ASI output card) it is recommended to use SERVICE PASSTHROUGH configuration. This method passes through all PIDs that are referred in PSI tables. This allows making changes in input card and then multiplexing can adapt automatically stream changes and reconfiguration in multiplexing is not needed. 7.1.7 PSI/SI table generation Luminato should let automatically generate PAT, PMT and SDT actual tables for streaming and multiplexing. Automatic table generation is enabled for these tables by default. NIT wizard can be used to create NIT tables to QAM and COFDM outputs, when QAM or COFDM outputs are located within one chassis. If Output modules (QAM outputs) are located in multiple chassis or system have multisite (multiple remote headend) configuration, then Teleste Broadcast Manager can be used create service line-up and SI table generation. 7.1.8 Variable- or constant bitrate streaming VBR/CBR setting is a functional property of input module’s IP output (excluding LAS-A). In output modules the IP-output is constant bit rate by default unless the null packet filter is enabled. In input modules the IP-output is in VBR-mode by default. However some third party equipments may require constant bit rate as a stream source to function correctly. In this case (CBR-mode enabled) the output stream is formed as constant bit rate by adding null-packets. Note: the output bit rate should be set high enough to allow the headroom for peak bit rates and hence to avoid stream corruption. Note also that the peak versus average bit rate ratio can be remarkably high. In order to keep the outgoing IP-stream strictly below the limit there is a special module-global setting: CBR strict mode (disabled by default). In strict mode the stream bit rate is limited by dropping packets. Strict mode ensures that the stream bit rate does not grow over the limit and may cause congestion at transmission network and possibly break other signals. In all cases the user is always alarmed if the packets are discarded due to corrupted stream. 54(68) CONFIGURATION GUIDE April 21, 2011 7.2 Service IP streaming (SPTS) This procedure presents steps for the simplest UDP/ IP streaming configuration creation. All special configurations and fine tunings are explained in other chapter. 7.2.1 Create IP streamer This chapter show how to create IP streamers for modules. Open OUTPUTS/All Outputs Tab and Edit IP outputs-link. Figure 41 IP output stream configuration 1. assign module (where streaming is created) from Slot drop down 2. give descriptive Alias name for streaming (this is for easy identification of streamer) 3. select bitrate mode to variable bitrate (VBR, default) or constant bitrate (CBR). Define bitrate box becomes available when CBR is selected. (note: bitrate mode is not available in LAS-A) 4. for example in the case of low bit rate streams it may be useful to choose low packet jitter mode (LPJ). The LPJ-mode minimizes the jitter caused by IP/UDP encapsulation. It allows variable length IP/UDP-packets. 5. choose interface: internal or common (default). Internal- interface is used for streaming between internal modules only. 6. enter Multicast IP group address (for example 239.1.1.1, unique address for each streamer) NOTE: It is recommended to use multicast address from range 239.1.1.1239.255.255.255 7. enter destination port (for example 45000, can be same for each streamer, if multicast group IP address is different for each streamer) 8. enter TTL (Time To Live, typical value is 5) 9. press ADD-button 10. Repeat as many output is needed 11. save entries 55(68) CONFIGURATION GUIDE April 21, 2011 7.2.2 Assign received service to IP streamer output This chapter describes method how to map service to IP streamer. Figure 42 Processing-page Processing 1. Choose Processing-link of IP streamer from MODULES page 2. Enable streaming 3. check Alias name and output IP address and Port 4. expand Output Advanced settings and ensure that PID allocation mode is SID mode. mode This mode use automatic PID remapping based on internal rules (SID and PID ranges). ranges). This method creates unique PIDs for every stream components. SID and PID ranges are set in system level configurations. Refer to chapter 4.3.2. 5. select service from drop dro down list in SERVICES section Figure 43 Module inputs are listed in left column. By selecting module input, service list has only services that are received in selected input. Figure 44 Select service from dropdown list When service is selected, Input SID and Service Name are copied to output fields. Byy pressing apply to confirm service, output SID is changed according to SID rules. CONFIGURATION GUIDE April 21, 2011 6. User can manually override output service id and service name. The entry box has orange surrounding, if values are manually changed changed. Figure 45 Output Service Name changed by user. 7. Accept configuration either Apply or OK-button. Using Apply-button Apply Processing Processing-page stays open. Using OK-button button the processing page is closed sed and returned to outputs page. By default streamer generates PAT, PMT and SDT actual tables to output stream. This configuration method includes all components in service to output streaming. Include and Exclude filters can be used to remove unwanted components or PIDs. The next chapter explains filter configuration. nfiguration. CONFIGURATION GUIDE April 21, 2011 7.2.3 Elementary stream filter and PID filter creation Luminato advanced filters can used to clean incoming services before route them to operator’s network. For example STB firmware private data streams for satellite STB should be removed to avoid all unintended software upgrades to Cable STB. Other data streams maybe also removed. Filters can be either include (“white list”) or exclude (“black list”). Include filter can be used selectively pick components. All other not matched are filtered (Exclude by default). This is recommended method to create filters. Exclude filter can be used selectively remove configured component. All other components are not filtered (Include by default). Figure 46 Service configuration including advanced filters Operator may include followed components: - video - all audio streams or selected language audios - AC3 audio - teletext - DVB subtitles Figure 47 Advanced filters - Pick only wanted components to streaming example Factory default is to include all components. To clean service default mode is changed to “exclude all by default”. Now user may actively pick wanted components. The above example picks up typical components: CONFIGURATION GUIDE April 21, 2011 - include ESTYPE video [100] -> includes all video components (typically only one) - include ESTYPE audio [100] -> includes all audio streams or - include ESTYPE audio [100] fin,swe -> includes fin, swe audio streams - include ESTYPE teletext [100] -> includes teletext streams - include ESTYPE subtitle [100] -> includes DVB subtitling streams User may include separately AC3 audio and standard audio ISO/IEC11172 audio to create appropriate filters. User may also add exclude filter for ECM to remove all incoming ECMs. Filter example is: - exclude ECM CA ID 2614 59(68) CONFIGURATION GUIDE April 21, 2011 7.2.4 Service Descrambling Luminato has flexible configuration for descrambling to define which services or its components are descrambled. This is essential in multiservice descrambling use cases. CA-modules typically have maximum limits for descrambled services and PIDs. Therefore user may need to configure only wanted services and its components for descrambling to maximise CA-module capacity use. Descrambling can be configured for full service or selected components. The followed picture shows selected component descrambling. 1. open Processing page of service to be descrambled 2. Enable full service descrambling using tick-box after input service name. Choose CA-module that is used for descrambling. 3. For selected component descrambling component extract service from “+”sign and select components to be descrambled. Partial descrambling causes ECM pass through, which may affect to STB operation. Therefore it is required to create filter ECM/EMM. Extract Component Filters and Exclude Rules. Create exclude ECM CA ID filter. Enter CA ID to filter parameter (see the above picture). This removes ECM and EMM from incoming stream. Figure 48 Service descrambling example After these steps services are available as IP streams and they can be measured from GE1 output, if SFP-module is installed. IP streams can be connected also to destination module within same chassis. CONFIGURATION GUIDE April 21, 2011 7.3 Service streaming (MPTS) This method is done very similar way than SPTS streaming. The only difference is to select multiple services to same IP output stream. This can be done, when processing page is open. Select from service drop down list all services that are included to MPTS streaming. Filtering and PID remapping can be done per service. Figure 49 MPTS streaming example 61(68) CONFIGURATION GUIDE April 21, 2011 7.4 Service routing to multiplexes This chapter introduces step by step guides to do service routing from IP domain to multiplexes. 7.4.1 Multiplex service pass-through configuration Service Pass-through-method is preferred to use in configurations, where SID, service names and PID values are set already in input modules. This configuration allows to pass-through all components or PIDs that are referred in PSI-tables. Therefore it is not needed reconfigure multiplexing, if incoming service is changed. Luminato multiplex can adapt automatically service change from ip-input. Figure 50 Creating IP inputs for ASI output or QAM output modules The first step is to define, what IP streams are received by a module. Create IP inputs for ASI output and QAM output modules 1.) Open Edit IP inputs-link on Configuration/INPUTS/IP Inputs-page (link is located at the bottom of page) 2.) Assign input to module in slot by selecting from Slot drop down 3.) Give Alias name for IP input 4.) Enter source ip address and ports, use * for any (this not usable yet) 5.) Enter destination IP address and port (same that you use in streamer output) 6.) press ADD-button 7.) repeat this process for all IP inputs 8.) Finally accept all changes by pressing SAVE-button. 62(68) CONFIGURATION GUIDE April 21, 2011 Assign inputs to multiplex 9.) Open Processing-link from output page for selected multiplex. Extract SERVICES PASSTHROUGH section and extract also INPUT SERVICES section. You should see all inputs that a are re configured to this module. Figure 51 SERVICES PASSTHROUGH multiplexing example 10.) enable inputs that are include to this multiplex by clicking check box of input. Check box enables service or multiple services services pass pass-through. 11.) when all needed inputs are enabled then confirm setting by Apply or OKbutton. This creates then multiplex, which combines input streams. Any change in input streams is dynamically dynamically reflected to output. 12.) the result can be read from SERVICES PASSTHROUGH OUTPUT SERVICES section. CONFIGURATION GUIDE April 21, 2011 7.4.2 Multiplex selective service configuration method Selective service-method enables intelligent filtering and remapping possibilities. This is very useful, if source streamer sends components that need to be filtered. Also PIDs can be remapped. Figure 52 Selective Service configuration method for multiplexing This example uses “selective services” –configuration method. Create IP input to module - this is same procedure that is explained in pass-through configuration method. Assign services to output 1.) Open Processing link of multiplex (ASI output or QAM output) on Outputs page 2.) Extract SERVICES-section 3.) choose from drop down list all service needed services to multiplex. 4.) confirm configuration by apply or OK-button 5.) now service specific filter or remapping can be created. Extract service to be configured. 64(68) CONFIGURATION GUIDE April 21, 2011 7.5 PSI/SI generation to multiplex When stream are organised to multiplex, then final step is to create valid PSI/SI tables to output transport streams. This chapter gives steps to create DVB compliant stream. By factory default Luminato inserts PAT, PMT and SDT actual tables. Also CAT table is generated automatically; if input stream has EMM streams. Automatic table generation can be enabled or disabled per table. Table editor can be used for create manual table insertion. Figure 53 GENERATE section - PSI/SI table generation configuration Followed steps give instruction to check and adjust PSI/SI table generation: 1.) Open Processing-link from output page for multiplex 2.) Extract GENERATE-section 3.) Check that PAT, SDT actual and CAT table generation is enabled. (NOTE: do not use NIT generation) 4.) Enable TDT/TOT insertion to transmit time and date information to setup box. 5.) Run NIT Wizard to enable also NIT table insertion. - choose Configuration-menu and then Wizards - Wizard –view opens - select NIT wizard and run it. Wizard goes forward in steps that user can adjust configuration if needed. 65(68) CONFIGURATION GUIDE April 21, 2011 7.5.1 NIT table creating using NIT WIZARD NIT wizard is designed to simplify NIT table (SDT other) generation within chassis Figure 54 example of NIT wizard step NIT wizard shows first a list of output muxes and prompts for Network ID and Network name. The user is allowed to choose one or more outputs to be included in the generated tables. The next step (3) asks for any modifications to NIT and SDT other settings. In step (4) the user is allowed to review the generated tables and to open table editor for editing if needed. Tables can also be download here (in binary format). Steps (5) and (6) allows the user to select output(s) where the generated tables are inserted and shows a summary before applying the changes to device. Now the STB box can be tuned to services and to watch programs. 66(68) CONFIGURATION GUIDE April 21, 2011 7.5.2 External SI table multiplexing System may have external SI generation like Teleste Broadcast manager. HINT: SI (System Information) PID values and table description PID Table type Description 16 NIT Network Information tables 17 SDT Service Descriptor Table 17 BAT Bouquet Association Table 18 EIT Event Information table 20 TDT Time Date Table TOT Time Offset Table External SI generator sends multicast streams, which includes SI tables in transport stream format. This kind of streams can be multiplexed with video/audio streams in Luminato multiplexer. The followed procedure gives guidance to create proper configuration for external SI table multiplexing. Configuration steps: Luminato output module will be configured to receive multicast stream from SI generator. This is done similarly than video stream reception to module. 1. Create IP input for multicast stream, which has SI tables. - Open Inputs-page and choose IP inputs –tab - scroll down and select Edit Inputs-link. - choose the module, where to create IP input for SI stream -select interface from dropdown-menu, where SI multicast stream is coming. - fill Alias-name and IP address and port information - press Add to complete IP input creation - Accept new entries by pressing Save-button 2. Open Processing-link from Outputs-page for multiplex 3. Extract PID FILTERING section (the last section). This is used to pick selected PID values to multiplex. 4. Select IP input from dropdown list The left column of New Entry has drop down list of all configured IP inputs to the module. (User can verify SI multicast stream IP input index number from Inputs-page) 5. Choose Filter Mode “Included” 6. Enter SI PID value to box right to drop down of Input PID NOTE: Input PID dropdown list has all scanned and detected PID values from incoming stream. Slow bitrate PIDs may be missing from list. User can enter unlisted PID by selecting empty line from dropdown list and enter input manually to next entry box. Figure 55 SI PID entry example 67(68) CONFIGURATION GUIDE April 21, 2011 7. Press Add-button 8. Repeat New Entry for all SI PIDs. Figure 56 External SI table multiplexing configuration finished (NIT 16, SDT/BAT 17, EIT 18, TDT,TOT 20 tables configured) 9. NOTE: Disable SDT autogeneration in case SDT is included from incoming multicast stream. - extract GENERATE-section - disable SDT automatically generated 10. Press Apply or OK-button to save settings Now SI tables from external source have been joined together video services in the output.
