DVB remultiplexer TRS180 1. Product description TRS180 is DVB MPEG2 transport stream remultiplexer. The purpose of the device - to extract services from MPEG2 TS, modify some it s information and multiplex with another services from any another input channel. Remultiplexer accepts and distributes MPEG2 DVB-ASI signals (according to EN 50083-9, ISO/IEC 13818-1, EN 300 468 standards and recommendations). Remultiplexer is intended to use together with MMH3000, CMH3000 headends as well as a stand alone device. The product is intended for indoor usage only. Not used in tropical climates. 2. Safety instructions The remultiplexer is powered from mains 230 V~. This voltage is dangerous to life. Any repairs must be done by a qualified personnel. To avoid the electric shock follow these instructions: Do not remove the cover of the power supply section, without isolating the unit from the mains supply. Do not plug the remultiplexer into the mains supply if the power cord or plug are damaged. Do not plug the remultiplexer into the mains supply until all cables have been connected correctly. To disconnect the remultiplexer, disconnect plug from mains socket. The mains socket must be easily accessible. The remultiplexer shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall be placed on it. Avoid placing remultiplexer next to central heating components and in areas of high humidity. No naked flame sources, such as lighted candles, should be placed on remultiplexer. If the remultiplexer has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging into the mains. The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains. 3.

Optionally connect Terra Bus cable to connector [11] OR Ethernet cable to connector [12]. Note: Only one of these interfaces should be used at a time! Connect power cable to 230V~ 50Hz power supply (connector [7]). Valid signal indicators [9] will light on if valid DVB-ASI signal is detected. Link indicator [13] will light on if Ethernet signal is detected. Blinking indicator [13] means activity of Ethernet interface. Note: wait at least 5 seconds after plugging in Ethernet connector to get Ethernet interface ready. Follow 7-9 management instructions to configure a device properly. 6. Default settings Output Bit Rate: 35.0 Mbit/s Date/Time channel: NONE Terra Bus Address: Device - 1; Subrack - 1 Network IP: 127.0.0.1 7. Web based control panel This panel is accessible from Terra Bus and Ethernet Interfaces. Use local control panel to configure communication parameters. Otherwise web based control panel will be inaccessible. Figure 1. Web based control panel. Home page. 7.1 HOME tab HOME tab (see figure 1.) shows information about the status of device and has buttons for main tools. Bit Rate Information table contains bit rate information about all input and output channels. Input channel bit rate is calculated including NULL packets on input channel. Output bit rate shows only a bit rate of selected services, excluding added NULL packets. System Status table shows the status of device. If there are any errors in the system, they will be shown in Errors section. Internal temperature of device is shown in Temperature section. Up time section shows running time since the last switching on of device. The page does not refresh itself automatically to update information of device in real time. It shows only the information, which was valid at the moment, when a page was loaded. Load streams button will load all service information from all connected inputs. It may take up to 30 seconds or more to load information from all channels. A progress bar with detail information about the status of process will be shown. A browser will be redirected to this page again as soon as all scan process will be finished. 5
Note: FireFox browser has too strict security policy, which prevents showing the status of progress in real time. In this case you ll not see the status information and will be redirected to the main page immediately. Equipment will respond only after a scan process will be finished. If the device is currently running, it s output will be disabled at scanning moment and all previously loaded information will be lost 1. When information of inputs has been scanned, it may be reviewed and managed by browsing through the tabs Input 1.. Input 8. All services will be disabled by default. They must be enabled by checking the corresponding checkbox for each service. See section 7.2 for more information. Save & RUN will save all information about selected services into non-volatile memory and start to run. Please ensure, that output bit rate is configured big enough to fit all selected services. See 7.4 section for more information. 7.2 Channel selection tab Input N tabs allows to manage all loaded services. See Figure 2. Figure 2. List of loaded services The 1 st column shows titles of all available services on selected channel. A lock near the title means that a service is scrambled. The 2 nd column shows program identification number and a sum of all streams bit rates 2 of each channel. Bit rate measurement does not run in parallel for all streams. Each stream s bit rate is measured 3 one by one. So in case, if only few seconds passed since the time of loaded streams (or power up), some services may not have this information. Refresh a page after a short time to see bit rates of the rest services. The 3 rd column allows to select services from a channel for remultiplexing. Press enable selected programs button after checking the corresponding checkbox. Information will be updated in memory, but will still not take action on output. It s necessary to press Save & RUN button on HOME tab to save it into non-volatile memory and start running. Each service has many inner parameters, which may be accessed and managed by pressing sign. Section 7.3 has information about it. Reload Channel button above the table allows to rescan the channel. All the rest channels will not be affected. 1 A copy of information will still reside in a non-volatile memory. So if it will not be overwritten by pressing Save & RUN, it still may be loaded by switching the device off and on. 2 It does not include EMM/ECM or any PSI tables. Usually their influence into total bit rate is negligible. 3 An average of bit rate is measured within 100 ms. Real bit rate maybe different. 6
7.3 Inner parameters of services If you are using Terra Link, CMH Master or Internet Explorer, be sure that Internet Explorer settings are correct. See 12.1 section for details. After pressing a, all information associated with a service will be loaded. Figure 3 shows an example. Figure 3. Inner parameters of service The 1 st column shows a type of information. The 2 nd column shows original information of service and a bit rate of each stream. The 3 rd column allows to modify some parameters of service. You can modify service title, service provider name, program ID number and most of stream PIDs. New PID numbers are generated automatically and does not require any further modification. However, a user has possibility to modify it. Any streams, owned by a service, can be enabled or disabled by checking/unchecking the checkbox on the 4 th column. The exception is a stream, which carries PCR information (a video stream in figure 3). Such stream (if any) will always be left enabled. Green triangle allows to control advanced settings of the streem. New selection item will appear after pressing onto the triangle. The type of the stream can be changed there. For example: H.264 video stream can be changed to MPEG2 video. Note: Only a description of this stream will be changed. The content of the stream will not be modified. Press Update Program Information button to submit modified parameters. Note: A service should be enabled itself in the main list of services. Otherwise modifications will not take affect. Figure 4. Cyrillic charset demonstration 7
Software automatically detects a charset of entered text. Figure 4 shows an example with cyrillic charset. Originally a service has a title TF1 with standard Latin charset. We switched a keyboard language to Russian and typed in Cyrillic characters. We received a service which has a title with Cyrillic charset (according to EN 300 468 - a Charset code table ISO/IEC 8859-5). Figure 5 shows a screenshot of MPEG-2 stream analyzer with a new Russian title. Figure 5. MPEG2 stream analyzer screenshot The right side of the window shows it. The left side of the window shows all PIDs (streams), which exists in the service. New remapped PIDs can be seen here. For example, original PID 2120 was changed to 297. 400-402 EMM tables are taken from CAT (Conditional Access Table) and carries information of service decryption. All CAT (Conditional Access Table) information is managed automatically and multiplexed (summed) with all input channels. In case, if selected service does not require conditional access information - related to it streams will be skipped or added/passed. If streams are already descrambled, but still has conditional access information - it can be permanently removed by deselecting all CA streams in service management window (a stream with original PID 1161 in the example above). 7.4 Output tab Output tab allows to manage output parameters. The most important parameter is output stream bit rate. All selected services must fit into it. It s recommended to setup at least 5-10% higher bit rate than selected services actually takes. Date/Time source selection table allows to select the source channel of data and time channel to pass. Only from one active channel this information can be passed to the output. PID No. 20 (TDT, TOT) in the figure 5 shows it. Network Information table allows to add a network title. It will be distributed as NIT with PID number 16. It may be disabled if empty string is submitted. 7.4.1 NIT configuration Several TS (Transport Streams) can be described in NIT (Network Information Table). At the 1 st stage, transport stream should be added into the list by pressing Add New TS button at Output tab. See figure 6: Figure 6. Stage 1 of NIT 8
Transport Stream ID field must be unique integer value for every TS. Orig. Network ID field should identify network according to ETR 162 [6]. When a new TS has been added into the list, several descriptors can be added to describe the TS. See figure 7. Figure 7. Stage 2 of NIT Select any of listed descriptors and press Insert New Record. New fields for adding information will appear. Many different descriptors can be added into the same TS. A sign will appear to the left of each added descriptor, for example: Pressing onto sign to edit values or remove descriptor from the list. For more information about each type of descriptor see EN 300 468 standard. After describing all TS, press Save & RUN button at Home tab to take affect and save it to memory. Note: NIT is available from 2.00 software version only. 7.5 Configuration tab Configuration tab allows to setup communication parameters. Terra Bus Parameters table has device and subrack addresses. After changing it, a device will be accessible at another address with Terra Link or CMH Master software. Network Parameters allows to change IP address of device. If this page is loaded via Ethernet, a browser will be redirected to another IP address after changing it. If the page is loaded via Terra Bus - no any redirection will occurs. 8. Ethernet Interface Device has 10/100 Mb Auto-MDIX Ethernet interface. It has ICMP (PING) and TCP/IP/HTTP protocols implemented. Device will respond to direct IP address requests as well as to any Host name, which is resolved to it s IP address. TCP/IP/HTTP protocol implementation allows to use any Internet Web browser available in the industry. For example: Internet Explorer, Opera, FireFox. Web browser will open a control panel described in section 7. 9. Terra Bus Interface This is a common management interface for most of equipments, manufactured by Terra. Device can be accessed via UD100 or UD200 device using Terra Link or CMH Master software. When a device is accessed using this interface, addressed indicator [4] will light on. Only one device on the bus can be addressed at a time. Terra Link version should be 1.3.0 or later to support this device. The latest Terra Link software can be downloaded from www.terraelectronics.com address DOWNLOADS section. 9

Hold esc button down for at least 1 second to return back to menu. 10.2.4 Enable Streams Enable Streams menu allows to manage all parameters of loaded data, enable/disable services. After entering into Enable Streams menu, a submenu with all scanned channels will be displayed. Channels, which have no signal at a scanning moment, will not be listed here. Enter into any available channel s menu. All service names will be listed as submenus of a channel. Select a desired service name and press enter for further management. The 1 st submenu item has title Disabled. Enter button will toggle it to Enabled and to Disabled again. It allows to select or deselect this service. If Enabled is currently selected, a sign near service title will also be displayed. Service Name allows to modify a name of service. See section 10.1 for information how to modify strings. Service Prov. allows to modify a service provider name. See section 10.1 for information how to modify strings. PMT PID menu allows to change PMT PID. See section 10.1 for information how to modify digital parameters. Manage Streams submenu allows to modify more parameters of selected service. All available streams of service will be listed here. 12
A Digit near the stream name means original PID number of this stream. Press Enter to modify parameters of selected stream. Three submenu items will appear. The 1 st menu item toggles between Enabled and Disabled. Change PID allows to modify PID number of the stream (see PMT PID description for more information). Change Type allows to change the type of stream. For example: if the stream is H.264 Video, it can be changed to MPEG2 Video. Only a description of the stream will be modified. Content of the stream will not be changed. View Bit Rate will show a bit rate of the stream in real time, including maximum bit rate. Esc button will reset maximum bit rate value. Esc button pressed for at least 1 second will exit to menu. 10.2.5 Output Params This is a management of all parameters related to signal output. Bit Rate allows to setup output bit rate. See section 10.1 for more information how to modify digital parameters. Network Info any text can be entered here. It will be sent in NIT (Network Information Table). Empty string here will disable sending this information. Date/Time Ch. allows to setup input channel from which a date/time information will be passed to the output. A sign will be added near the selected item when enter will be pressed. If NONE will be selected no any data/time information will be sent. Currently selected services table shows summary of all currently selected services (see figure 11). 10.2.6 Communication Figure 11. Currently selected services Communication menu allows to setup device addresses to access it from remote. Terra Bus Addr has two submenus - Position No and Subrack No. These parameters are necessary to setup to access a device with TerraLink or CMH Master software. Note: only one device with the same address combination allowed on the same data bus. Network IP allows to modify IP address to access it via Ethernet. See section 10.1 for information how to change digital parameters. 13
10.2.7 Save & RUN Save & RUN will save selected parameters to non-volatile memory and start running with new parameters. 11. Operating After a system startup, the device will load all previously saved information and continue to run according to it. Current configuration of selected services will be available to access using Web based interface (7.2) and local panel (10.2.4). If input signals where not changed all management is possible without reloading streams and without interrupting operation. However, when saving new data, a short interrupt of output signal may occurs. If at least one signal of previously saved configuration is disconnected, status indicator [5] will change a light to red indicating an error. If output signal bandwidth does not fit into configured output bit rate, red status indicator [5] will light on indicating an error. All errors may be reviewed using local control panel (10.2.2) or using Web based control panel (7.1). 12. Recommended sequence of management Power on a device. Connect cables to Input n and Output channels. Use Load Streams command to load all information from input channels. Enable all necessary services from all channels. Select Data/Time channel for data and time information to pass. Setup output bit rate. Press Save & RUN. A device will start to work. Check output bit rate to be sure that all selected services fits and exists at least 5-10% unused bandwidth. It will ensure, that any short increment of bandwidth in input channel will not be truncated and will pass to the output. 12.1 Recommended internet explorer settings There is very important to make correct Internet Explorer (IE) settings. Otherwise some settings of remultiplexer will be reloaded from catch, and not from remultiplexer. It s necessary to update these settings even if you are not using IE to control remultiplexer via Ethernet. These settings will be used for Terra Link, CMH Master software as well. Steps to make correct configuration: - Load Internet Explorer; - Load Internet options from menu Tools ; - Press settings and select Every visit to the page. See figure 12 for example. Note: Your window may have slight different view depending on Internet Explorer version. Figure 12. 14
