Table 1.1: Equipment Models Model Number Product Number Description E5910 M2/ESN/SNGA The basic DSNG Codec not fitted with an Integral Receiver-Decoder (IRD) Card (early models of this equipment). E5910 M2/ESN/SNGB The basic DSNG Codec fitted with an Integral Receiver-Decoder (IRD) Card (S5902). On the rear panel of the equipment is a label which identifies the Product Title, Product Number, Serial Number and Build Status. Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 1-3 Introduction 1.2 Function of the DSNG Codec The DSNG Codec is a low bit-rate, transportable, digital exciter designed specifically for digital satellite news gathering applications. It is compact and lightweight, fully MPEG-2 and DVB compliant, and has high performance for the transmission of studio-quality video material. The equipment is designed to be suitable for both flyaway use (within an appropriate flight case) and truck installation. A single 5U chassis houses video, audio and data encoding, multiplexing and modulation functions. The unit is fully configurable and extremely flexible, while still being simple to operate and maintain. Various alignment, testing and diagnostic facilities have been incorporated to assist with operation and maintenance in the field. The DSNG Codec provides a single video channel, accepting either digital, composite or component inputs which are to be encoded. Transponder bandwidth can be traded with video quality by operating the video compression bit-rate in the range 1.5 -15 Mbit/s. Over this operating range, encoded video resolution can be controlled in order to optimise subjective encoding performance. Video, audio and data inputs DSNG Codec 70/140 MHz IF Up-converter and HPA System 3000 Professional Satellite IRD Video, audio and data outputs Video and Audio Monitoring Figure 1.1 DSNG Codec Basic System Configuration The unit encodes four channels of analogue audio which may be configured as four mono channels, or two stereo pairs, or two channels of AES/EBU digital audio. Two channels of asynchronous and one channel of high speed synchronous data are also supported (data channels are not compressed). Page 1-4 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Introduction The unit multiplexes these input signals and adds digital scrambling, under user control, to provide secure programme transmission. The digital stream is then processed for forward error correction (FEC) and modulates a single IF carrier (tuneable around 70 or 140 MHz) for output to an Up-converter and High Power Amplifier (HPA) equipment for transmission to the satellite. The error correction and modulation scheme used is DVBcompliant, using concatenated Reed-Solomon (188, 204) and Convolutional Encoding (selectable rate 1/2 to 7/8). A baseband output to the DVB parallel standard is also provided. If fitted with an Integrated Receiver-Decoder (IRD) Card (M2/ESN/SNGB option only), monitoring of the local signal, or off-air reception of the uplinked, or even an unrelated compressed service off satellite, is possible. This provides a reliable means of ensuring the DSNG Codec is functioning correctly, eliminating the need to rely on an established link back to the studio, or on a separate receiver at the uplink site. In normal operation this monitors the baseband or dedicated IF output, but also has an L-band input capability which can be used to monitor the outgoing feed (where a two stage up-conversion is used), or a feed off satellite. The L-band IRD input can power a receive LNB. 1.3 Summary of Features 1.3.1 Video Encoding Encoding Standards The DSNG Codec processes a broadcast-standard video signal into a compressed encoded bit-stream in accordance with the MPEG-2 specification (ISO/IEC 13818-2). Video Input Sources The following video input types are supported: n PAL-B/D/G/H/I/M and NTSC-M composite input n Parallel digital (ITU-R BT. 656-1 part 2) input (“D1” parallel format) n Serial digital (ITU-R BT. 656-1 part 3) input (“D1” serial format) n EBU N10 YUV component input n Betacam component input n internal test pattern Variable Bit-rate The MPEG-2 compression algorithm uses adaptive field / frame coding, forward and backward predictive processing with motion estimation and compensation to reduce the bit-rate to within the range 1.5 - 15 Mbit/s. NOTE… SIF rate 1.5 - 5 Mbit/s (see Coding Resolutions). All other resolutions 2 - 15 Mbit/s. Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 1-5 Introduction Automatic Configuration of Parameters In normal operation, the unit will automatically select the video coding parameters, such as bit-rate and resolution, which deliver optimum video quality given the output configuration, i.e. bandwidth and FEC rate, set by the user. Alternatively, the user can override this and select manual control. Coding Resolutions To provide optimum picture quality over the full range of supported bitrates, the encoded picture resolution is normally controlled automatically according to the video bit-rate. Alternatively, the user can override this and select manual control. The available coding resolutions are as follows: Table 1.1: Video Coding Resolutions 625 Line Modes 525 Line Modes 704 pixels x 576 lines 704 pixels x 480 lines 544 pixels x 576 lines 544 pixels x 480 lines 480 pixels x 576 lines 480 pixels x 480 lines 352 pixels x 576 lines 352 pixels x 480 lines 352 pixels x 288 lines (SIF) 352 pixels x 240 lines (SIF) SIF resolution mode allows video bit-rates down to 1.5 Mbit/s and provides a better coding quality than normal resolutions at very low rates. However, as it is only intended for low rates, the maximum rate in this mode is limited to 5 Mbit/s. As the bit-rate is increased from 2 Mbit/s, the other resolutions gradually provide better quality than SIF. Low Delay Mode Low delay coding modes are optimised to minimise the end-to-end encoding delay. In these modes the video quality is traded against the delay. Internal Frame Synchroniser An internal frame synchroniser is incorporated to maintain a valid encoded bit-stream in the event of input video sync loss or hot cuts of video input. The encoding process which operates on the output side of the video synchroniser is frequency-locked to a stable internal video clock reference, ensuring accuracy of video reconstruction at the receive site. Output on Video Loss The unit can be software-configured to provide a black frame or to freeze frame in the event of video input loss. Frame Sequence Control In normal operation, the DSNG Codec uses IBBP coding, for which it has been optimised. The user can override this default and select either IBP or IP coding, as required. Coding modes and frame sequences are explained in Chapter 4, Equipment Description. Page 1-6 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Introduction 1.3.2 Audio Encoding Encoding Standards Audio is encoded to the MPEG-2 Audio Encoding standard (Layer 1 or 2) at a sampling rate of 48 kHz. Channel Modes The DSNG Codec supports four channels of audio, which may be configured as follows: n Four, analogue single mono channels (600 Ω or 20 kΩ) n Two, analogue stereo pairs (600 Ω or 20 kΩ) n Two, digital channels (AES/EBU) The two stereo pairs, may be configured in various encoding modes: n Single mono: the left channel is encoded - the signal is output to both XLR connectors at the receiving end n Dual mono: two mono signals are carried in the transport stream as a single PES data stream - only one of the two channels is decoded and output to both XLR connectors at the receiving end. This is intended for multi-lingual services n Stereo: a stereo pair is coded as two mono signals - the two signals are output as stereo at the receiving end n Joint/intensity stereo: a stereo pair is coded taking advantage of the stereo nature of the channels - the two signals are output as stereo at the receiving end Variable Bit-rate Output bit-rate is selectable in the range 32-384 kbit/s (dependent on configuration). Table 1.2: Audio Encoding Bit-rates Bit-rate (kbit/s) Single Mono Dual Mono 32 ä - - - 48 ä - - - 56 ä - - - 64 ä ä ä ä 80 ä - - - 96 ä ä ä ä 112 ä ä ä ä 128 ä ä ä ä 160 ä ä ä ä 192 ä ä ä ä 224 - ä ä ä 256 - ä ä ä 320 - ä ä ä 384 - ä ä ä Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Dual Stereo Dual Joint / Intensity Stereo Page 1-7 Introduction Test Tone and Level Display The equipment can be configured to generate a test tone for alignment purposes, and can also indicate audio input levels via the front panel display. 1.3.3 Data Channels The equipment provides data channels that operate as bit-pipes between the Codec and Decoders. Two types of data channel are supported: n Synchronous RS-422: One channel is supported at baud rates of: n x 64 kbit/s where n = 1 to 16, i.e. maximum rate is 1024 kbit/s. Data and clock are sourced externally to the Codec. n Asynchronous RS-232: Two channels are supported at baud rates of: 1200, 2400, 4800, 9600 baud. The transfer control mechanism is XON/XOFF. 1.3.4 Multiplexing MPEG-2 and DVB Compliance The main function of the Multiplexer is to construct an output stream made up of a multiplex of all data sources in the system in such a way as to conform to the MPEG-2 transport layer specification (ISO/IEC 13818-1 MPEG-2 Systems). Programme Specific Information is provided in its basic form and is DVB-compliant. Service name and language descriptor can be defined by the user. DVB Transport Stream Output A baseband output comprising the compressed and multiplexed data is available for telecommunications link application. The output conforms to DVB Professional Parallel recommendation and operates at data rates in the range 2 Mbit/s to 32 Mbit/s. Security of Transmission A form of elementary security, designed simply to prevent open access to the transmitted service is provided on the DSNG Codec. The DMV Remote Authorisation System (RAS1) uses a fixed key code to scramble the encoded data. The key code can be changed under software control and then stored for future recall. The key code being used must be entered manually at the receiving end to permit descrambling. Scrambling can be disabled to permit open access to the transmitted service. 1.3.5 IF Modulation The IF Modulator provides the satellite transmission functions specified for MPEG-2 packet signals to the transmission specification defined by ‘Digital Broadcasting Systems for Television, Sound and Data services’, ETS 300 421, December 1994. The DSNG Codec utilises QPSK modulation at 70 MHz (±20 MHz) or 140 MHz (± 40 MHz) which outputs data at a rate of 1.5-16 MSymbol/s. The output incorporates a pulse shaping filter and spectrum inversion (selectable) and operates in the range -27 dBm to +5 dBm. Two IF monitor outputs are also available, one of which provides a dedicated feed to the integral IRD. Page 1-8 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Introduction 1.3.6 Integrated Receiver-Decoder (IRD) The IRD (MS/ESN/SNGB option only) comprises a digital Demodulator and single-channel Decoder. Local Monitoring In local monitoring mode, the IRD monitors the IF monitor output from the Encoder unit or, alternatively, an internal serial feed at baseband, and decodes the input video and audio services, presenting these for local monitoring and reporting status via the user controls. Off-Satellite Monitoring / Independent Service Reception Additionally, a tuner is incorporated which can accept an L-band input. This can either be an intermediate output from the up-linking Up-converter (again for local monitoring), or can be from a satellite receive installation Low Noise Block (LNB) via the signal down lead. In the latter case receive polarisation switching is user selectable by the d.c. voltage fed to the LNB. The LNB d.c. supply can also be switched off under user control. Alternatively, the unit can accept a parallel baseband digital input on an interface designed to comply with the DVB Professional Parallel Interface Recommendation. When operating from L-band input, microprocessor-controlled tuning, with a frequency synthesised local oscillator, is used. The baseband output signals from the L-band tuner are then passed to a Quadrature Phase Shift Keying (QPSK) Demodulator. The demodulated data stream is demultiplexed before being passed to the Decoder. The Decoder further demultiplexes the data stream to select audio, video and data services received from the digital Demodulator. These services are then decoded, and presented at the IRD outputs. The Decoder can decode both Single Channel Per Carrier (SCPC) and Multi-Channel Per Carrier (MCPC) transmissions and will operate with net input data rates in the range 2 Mbit/s to 45 Mbit/s. 1.3.7 Unit Control and Monitoring Remote Control The DSNG Codec may be controlled locally via the front panel, or remotely via an RS-485/RS-422 interface (see DSNG Codec Remote Control Interface Specification ST.TS.E5910). When the unit is under local control, the remote control facility is disabled. When the unit is in remote control, only status information can be accessed from the front panel controls; all control commands then come from the remote link. Local Control Local control and operation of the unit is effected by a membrane keypad and a 20-character by 4-line display which uses a simple menu driven system (see Chapter 3, Local Control and Operation for details). Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 1-9 Introduction Reset/Alarm/Fail Relays Relay contacts are available at the RESET/STATUS connector to permit remote monitoring of the DSNG Codec which provides changeover relay contacts for alarm and fail indications (video, audio, data and IRD alarms may be included or masked), and a two-wire input for remote reset of the equipment. These relays are active when operating in either local or remote mode (see Chapter 5, Pr4eventive Maintenance and Fault-finding for more information). Configuration and Storage Up to 16 editable current configurations can be named and stored in memory by the user; the active current configuration is automatically restored at power on, provided that it has been stored - this happens automatically when the user exits Setup mode. In addition, a set of 16 backup configurations may be stored / retrieved under password protection. Alternatively, the original 16 factory default configurations (see Annex C, Default Configurations) may be restored at any time (see Chapter 3, Local Control and Operation for more information). Diagnostics Power-up and self-test diagnostic facilities are available to assist with operation and maintenance down to card level.

Introduction 3.1.1 Using Local Control This chapter describes in detail, the Digital Satellite News Gathering Coder/Decoder controls, indicators and display screens, and the operations which may be performed using them. The display is ergonomically designed, requiring only a few key presses to access the shallow hierarchy of menus, with only meaningful and relevant options displayed. If you are unfamiliar with this equipment a Getting Started guide is provided in this chapter to take you step-by-step through the setting up procedure. Once the equipment is set-up and running, there are normally no further Operator actions required, unless there is a requirement to change the set-up to accommodate a different configuration of input or output. 3.1.2 Using Remote Control Everything which can be controlled and monitored at the front panel display can be accessed remotely by using a suitable protocol and set of NDS proprietary remote commands via the rear panel remote control port (see DSNG Codec Remote Control Interface Specification ST.TS.E5910). 3.2 Controls and Indicators 3.2.1 LED Colour Coding Philosophy There are three LED colours used in this equipment: Red is used to indicate fault conditions, e.g. a missing or faulty input signal. For correct operation, all red LEDs must be off, although some may be on briefly during power-up; Yellow is used to indicate various system status conditions, e.g. Multiplexer occupancy. Thus, for normal operation, yellow LEDs may be either on or off, or flashing; Green is used to indicate correct conditions and correct system functioning. For normal operation, all green LEDs must be on continuously. This colour coding principle was devised to facilitate instant perception by the Operator of the equipment operational status, i.e. any red LEDs on or green LEDs permanently off indicates a fault condition. NOTE… If operating in Baseband mode, the red LEDs relating to the IF stage will be lit on the MuxMod Card S5898 and IRD Card S5902 (see Chapter 4, Equipment Description for a description of the rear panel LEDs). Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 3-3 Local Control and Operation 3.2.2 Front Panel Controls and Indicators The front panel (Figure 3.1) provides various keys and LEDs (Table 3.1). Figure 3.1: Front Panel Controls and Indicators Table 3.1: Front Panel Controls and Indicators Key / Indicator Description Control LEDs: Live This green LED is lit when the equipment is “on-air”. Local Control This yellow LED is lit when the unit is under local (front panel) control. Remote Control This yellow LED is lit when the unit is under remote control. Status LEDs: Alarm This red LED is lit when a failure of the equipment has been detected (accompanies triggering of the ALARM relay, the contacts of which are available on the rear panel RESET / STATUS connector). Power This green LED is lit when ac power is being received. Mode Keys: NOTE… If Setup or Diagnostics are not selected, the unit is in Status mode. Setup This key selects Setup mode and provides relevant options on the display for changing system setup parameters. The keys contain an integral green LED which is lit when the key is pressed. Diagnostics This key selects Diagnostics mode and provides relevant options on the display for running system diagnostics. The keys contain an integral green LED which is lit when the key is pressed. Keypad: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ., - These keys permit numerical input to be entered on some display pages to select options or enter parameter values. Clear This key takes you back to the previous display, or cancels any changes to parameter values which have been keyed in but not yet entered. Enter This key is used to select options and to confirm that changes made to parameter values are accepted. Cursor Keys: <>∧∨ These keys are used to move around the display pages and select menu options. The > key may duplicate the function of the Enter key, and the < key duplicate the Clear key on certain pages where these keys would serve no other useful purpose. Function Keys: System, Modulator, Mux, Video, Audio, Data, Receiver These keys select the functional areas of the unit and provide relevant options on the display, depending on whether Status, Setup or Diagnostics mode is selected. The keys contain an integral green LED which is lit when the key is pressed. Page 3-4 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Local Control and Operation 3.2.3 Rear Panel Controls and Indicators LEDs on each of the cards which comprise the DSNG Codec are visible at the rear panel of the unit. For normal operation, these LEDs are not needed. See Chapter 4, Equipment Description for a description of the on-card LEDs. 3.3 Getting Started 3.3.1 Choosing Parameters The following check list provides a guide to getting the equipment up and running. It assumes that the equipment is to be operated locally using the front panel display. However, the same sequence of events is also valid for remote operation. Familiarise yourself with the operating controls and indicators on the front panel of the unit (see Controls and Indicators). This will enable you to find your way around the various display pages (see Navigating the Display Screens later in this chapter). 1. Switch On the DSNG Codec. With the DSNG Codec correctly installed, switch on the equipment in accordance with the instructions given in Powering Up/Down. Confirm that it powers up correctly. If it does not, refer to Chapter 6, Fault Finding. 2. Check Configuration. Check the Status screens to confirm whether the currently set parameters for each functional area (System, Modulator, Mux, Video, Audio, Data and Receiver) meet with your requirements. If they do, then the unit is ready for operation; switch on the audio and data services and turn on the video by selecting the input source. If parameters need to be changed, proceed to next step. If not, proceed to step 4. 3. Change Configuration. If the required parameters are saved as a configuration file then load the relevant file (see Setup / Load Stored Config) and proceed to step 4. If not: a) Set All Audio Parameters. Enable audio channels, set the coding mode, input type, bit-rate, and all other parameters, as required. See Chapter 1, Introduction for a table of the supported bit-rates which are dependent on chosen mode. b) Set All Data Parameters. Enable data channels, set baud-rates, as required. c) Select IF or Baseband Operation. Using the Setup / Mux / Output Format option, select the required output format (IF or Baseband). This enables access to the relevant Modulator and/or Multiplexer parameters. Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 3-5 Local Control and Operation d) Set Multiplexer Parameters. Select and modify the multiplexing parameters as required (bit-rate, packet length, RS encoding, scrambling). Video bit-rate and pixel resolution will be determined automatically to optimise the system and fully utilise the baseband output bit-rate. By default the baseband output will be on unless stored as off. e) Set Modulator and Multiplexer Parameters. Select and modify the modulation parameters as required (IF output power, IF frequency, bandwidth, FEC rate, spectrum inversion). Symbol rate, video bit-rate and pixel resolution will be determined automatically to optimise the system and fully utilise the available bandwidth. Set scrambling as required using the Setup / Mux screen. By default the IF output will be off. Turn IF output and modulation on when ready to transmit. f) Check Video Bit-Rate and Resolution. These parameters will have been set automatically according to the selections made above. Check that the values set meet your needs. If not, you may make manual adjustments to reduce the audio and data requirements to free up more bandwidth to allow higher resolution video to be processed. g) Set Receiver Parameters. Check that the IRD is connected and set up to receive the transmission. NOTE… If manual changes are made to the configuration, and too low a bandwidth / symbol rate is entered for the required services, the display will offer the option to switch off the services in the following order: Video, Audio B, Audio A, RS422, RS232 Ch A, RS232 Ch B. Similarly when increasing bandwidth / symbol rate, the display offers the choice of whether to restore services or not. 4. Turn on the Output Turn the output of the unit on to begin transmitting; Baseband output is on by default, IF Output is off by default. If using the IF output, turn on both the modulation and the IF output. 3.3.2 Automatic Data Rate Selection IF Operation The starting point is usually to enter the bandwidth that has been allocated for use on the Satellite Transponder. Normally, the output symbol rate and the video bit-rate are calculated automatically corresponding to the entry of bandwidth and FEC rate parameters. In this way the DSNG Codec is optimised and system capacity is not exceeded. This automated process takes into account the data rates which have been allocated (manually) to audio and data services. From the permissible bit-rate, the pixel resolution is selected automatically to maximise the quality of the video channel.

Normally, the video bitrate is calculated automatically corresponding to the entry of these parameters. In this way the DSNG Codec is optimised and system capacity is not exceeded. This automated process takes into account the data rates which have been allocated (manually) to audio and data services. From the permissible bit-rate, the pixel resolution is selected automatically to maximise the quality of the video channel. Enter Mux Bit Rate Packet Length Audio Services Data Services Automatically calculates Video Bit Rate Automatically selects Pixel Resolution Figure 3.3: Data Rate Automatic Selection (Baseband Operation) 3.3.3 Manual Data Rate Selection Automatic selections may, if required, be overridden to suit particular requirements. The block diagram below (Figure 3.4) illustrates the general principles and functions which are used in order to calculate the useful data rate which may then be allocated to the video, audio and data services. Multiplexer 188 bytes of data converts to 204 bytes (selectable) 1 Video 1.5-15 Mbit/s Up to 4 Audio 32-384 kbit/s 1 Data (Sync) 64-1024 kbit/s Up to 2 Data (Async) 1200-9600 baud Packet Length Baseband Output 2-32 Mbit/s 188 or 204 bytes in baseband Modulator MPEG Formatting Headers 184 bytes of data converts to 188 RS Encoding Coding expands every 188 bytes to 204 Convolutional FEC Rates of 1/2, 2/3, 3/4, 5/6, 7/8 may be used Modulation QPSK Each symbol represents 2 bits Pulse Shaping Filter Scale factor of 1 Scaling factor of approx. 1.28 IF Output 1.5-16 MSym/s CA/PSI & Overhead approx. 400 kbit/s (not selectable) Figure 3.4: Data Rate Manual Selection Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 3-7 Local Control and Operation The ratio used for transponder bandwidth over symbol rate is approximately 1.28. Therefore, the maximum useful data rate in IF output mode is: BW x 1 x 2 x FEC x 1.28 188 204 x 184 Mbit/s 188 The maximum useful data rate in Baseband output mode, with RS encoding is: mux rate x 188 204 x 184 Mbit/s 188 The maximum useful data rate in Baseband output mode, without RS encoding is: mux rate x 184 Mbit/s 188 3.3.4 Configuration File Loading and Storage The parameters currently in use may be stored and retrieved as desired to prevent having to re-enter all the corresponding values and settings every time the unit is borrowed or temporarily changed to suit other requirements. NOTE… The parameters currently in use are restored when the equipment is turned off and back on again, providing that the configuration has been stored - this happens automatically when the user exits Setup mode. Using the Setup / Store Current Conf option, the current configuration being used may be stored as a file for future use. Up to 16 such configurations may be named and stored as files. Any of these configurations may be loaded as the current configuration by using the Setup / Load Stored Config option. The configurations may be altered by using the Setup / Edit Confg Title option. In addition, another set of 16 configurations may be stored and retrieved under password protection using the Setup / Backup Configs option. This prevents unauthorised personnel from changing parameters which have been optimised for existing situations. The current set of user configurations may also be restored to the original factory defaults using the Setup / Restore Orig Confgs option (see Annex C for a complete listing of parameter values and settings for the default configurations).

Before powering up the DSNG Codec, check the following: 1. The DSNG Codec enclosure has been properly installed in a suitable location (see Chapter 2, Installation). 2. The DSNG Codec has been connected to external equipment and power supply, as required. NOTE… All other connecting equipment, such as an up-converter, video source, etc., may be switched on either before or after the DSNG Codec and will not result in damage, lockup, or otherwise interfere with the operation of the DSNG Codec. 3. 4. Power supply has been checked and a good earth provided. Ensure the correct fuse type and rating has been fitted to both the equipment and the ac power cable. 3.4.2 Powering Up To power up the DSNG Codec: 1. Power up the DSNG Codec by setting the integral power switch at the rear panel power inlet connector to on (I). The equipment will execute a series of power-up initialisation and selftest routines which may take up to one minute. 2. Confirm that power is available throughout the DSNG Codec, if not refer to Chapter 5, Preventive Maintenance and Fault-finding: a) Front Panel Indicators - Confirm that the green Power LED is lit and that the red Alarm LED is unlit. b) Rear Panel LEDs - At the rear panel, confirm that there are no unexpected red LEDs lit, and that all green LEDs are lit (see Chapter 4, Equipment Description).

A description of the on-card LEDs visible at the rear panel is also given here. 4.2 Video Coding 4.2.1 General The fundamental objective of the coding scheme is to exploit information redundancy in the input video signal to minimise the amount of data required for successful transmission. To achieve this, the DSNG Codec uses a number of interactive processes. The resultant compressed bit-stream syntax conforms to the ISO 13818 standard. An explanation of the overall coding strategy follows. 4.2.2 Frame Types Coding operates on a frame (or picture) based principle. There are three frame types: n I (intra-coded frames), n P (predicted frames), n B (bi-directionally predicted frames). P and B frames are known as inter-coded frames. Coding of I frames occurs without reference to any other frames. P frames use motion compensation from a previous I or P frame. B frames are coded using motion compensation from a previous and/or a future I or P frame. Thus, a coding scheme may contain a mix of I, B and P. Figure 4.1 illustrates the coding process. I Frames → Digital/ Analogue Video In Intra Pre-processing B or P Frames → Predicted Frame and Difference Signal Generation Error Common Path Processing Functions (DCT coding Inter Quantisation VLC encoding) Compressed Video Out Motion Vectors Figure 4.1: Coding Scheme Block Diagram Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 4-3 Equipment Description The motion-compensated-predicted frame is subtracted from the current frame to produce a frame difference or prediction-error value. This prediction-error value is coded instead of the complete frame information, thus affording a considerable saving in bit-rate; this mode of operation is known as "inter-frame" coding. The prediction-error information is augmented by motion vector information which is also coded and enables recovery of the current complete frame information by a Decoder. The I frames and prediction-error values are processed in blocks of 8x8 pixels which are first transformed by a Discrete Cosine Transform (DCT). For typical images, the distribution of the coefficients is not uniform due to spatial redundancy, and the energy tends to be concentrated into the low frequency coefficients. The number of bits required for a block is reduced by not transmitting the near-zero coefficients and by quantising the remaining ones. Quantisation results in a reduction of the number of possible values to be transmitted. These values are then entropy-coded using a Variable Length Code (VLC). The VLC allocates codes which have different length depending upon the probability with which they are expected to occur. NOTE… The motion estimation and DCT coding can be field or frame based to achieve a better coding efficiency. 4.2.3 Frame Sequence Depending on the coding mode used, P or B frames are produced for inter coding. The regular transmission of an I frame provides a regular reference from which predicted frames can be generated, thereby ensuring that predictions do not become wildly inaccurate and give a starting point for decoding. The run of frames from the start of an I frame to the start of the next I frame is known as a group of pictures (GOP). Each GOP is identified by a unique header. The GOP structure for PAL is fixed in length at 12 frames, and can be of the following format: n IPPPPPPPPPPPI, for non-B frame operation (IP) n IBPBPBPBPBPBI, for operation with B frames (IPB) n IBBPBBPBBPBBI, for successive B frames (IBBP) The GOP structure for NTSC is either 14 or 15 frames, and can be of the following format: n IPPPPPPPPPPPI, for non-B frame operation (IP) - 15 frames n IBPBPBPBPBPBI, for operation with B frames (IPB) - 14 frames n IBBPBBPBBPBBI, for successive B frames (IBBP) - 15 frames Page 4-4 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Equipment Description 4.3 Audio Coding Audio encoding is to the MPEG-2 encoding standard ISO/IEC 13818-3 (layer 1 or 2) at a sampling rate of 48 kHz. The spectrum of the received broad-band audio signal is divided into subbands of equal bandwidth by filtering. Each of these sub-bands is separately sampled and quantised to convert the input analogue signal into a sequence of discrete sample values. The samples associated with each sub-band are separately coded according to the psycho-acoustic properties of the human auditory system. Critical regions are coded more accurately, with less bits being assigned to frequencies at which the ear is less sensitive. Coding is also dependent on dynamic information such as audio masking, in which a loud sound at one frequency dominates over any quieter sounds at adjacent frequencies. Adaptive Differential Pulse Code Modulation (ADPCM) techniques are used to reduce the bit-rate by coding the difference values between successive samples rather than absolute values. Quantisation step size is adjusted depending on the magnitude of the difference value: a rapid change produces a coarse approximation followed by smaller, more precise successive samples. For all coding modes (stereo, mono, dual mono and joint stereo) the digitally coded bits are formatted into distinct frames, each of which contains a header which defines the frame in detail (coding scheme, mode, bit-rate, etc.). Since the number of useful bits varies depending on the psychoacoustic properties of the corresponding sound samples, the frame can be padded. The resultant encoded audio output bit-rate is software selectable in the range 32 kHz to 384 kHz, depending on the mode selected (see Chapter 1, Introduction for table of supported bit-rates). 4.4 Data Handling The synchronous and asynchronous data channels provided by the Encoder are simple bit-pipes and are not coded in any way. This is due to the fact that the nature of the data to be transmitted is expected to be different for individual customers and, therefore, a suitable coding scheme cannot be provided with any guarantee of performance. 4.5 Codec Functional Description 4.5.1 Overview Either analogue composite / component, or digital parallel / serial video may be applied to the Video Input Card (Figure 4.2). The Video Input Card synchronises the input video to an internal reference clock and digitises the video signal to a Y/Cb/Cr 656 format and provides down-sampling, if required. The MPEG-2 Video Encoder Card takes in the digitised video signal and processes it to a compressed encoded bit-stream in accordance with the MPEG-2 video specification. Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 4-5 Equipment Description Coded video information (the amount of redundant information removed can be as high as 95%) is routed to the Multiplexer / Baseband Modulator Card were it is combined with coded audio and data (uncoded) information from the Audio, Data and Teletext (ADT) Card. The Multiplexer / Baseband Modulator Card provides a DVB-compliant multiplexed output of the video, audio and data signals and inserts user Conditional Access (CA) and Programme Specific Information (PSI). The output is routed directly to an output connector and to the IRD Card. Data is passed through a convolutional encoder and a pulse shaping filter (√35% cosine roll-off) before being routed to the IF Modulator Card. The card also provides the user control interface to the front panel for local control, and to a rear panel connector for remote control. The IF Modulator provides the satellite conditioning to the multiplexed MPEG-2 / DVB transport packets. A 70 / 140 MHz carrier is QPSK modulated with the data output for routing to Up-converter and HPA. The IF output may be monitored locally by the Integrated Receiver-Decoder (IRD) Card (M2/ESN/SNGB option only) which provides the necessary demodulation and demultiplexing to restore the original video, audio and data signals. Additionally, the IRD also accepts an L-band input or an unmodulated DVB parallel input.

Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 5-5 Preventive Maintenance and Fault-finding 5.2 Fault-finding 5.2.1 Maintenance Philosophy The following sections provide fault-finding procedures to follow in the event of a suspected DSNG Codec failure. It is assumed that other equipment units have been eliminated as the possible cause of the failure (see relevant documentation). WARNING… HAZARDOUS VOLTAGES ARE PRESENT WITHIN THIS EQUIPMENT AND MAY BE EXPOSED IF THE COVERS ARE REMOVED. ONLY QUALIFIED AND TRAINED SERVICE ENGINEERS ARE PERMITTED TO SERVICE THIS EQUIPMENT. It is the objective of this chapter to provide sufficient information to enable the rectification of apparent faults by Operator action, or else to identify the suspect card or module, where possible. In the event that the recommended action fails to clear the abnormal condition, call a Service Engineer or contact Customer Support using the information given in the preliminary pages of this manual. IMPORTANT NOTE… Unauthorised maintenance or the use of non-approved replacements may invalidate any warranties and/or affect the equipment specification. 5.2.2 Fault Diagnosis and Rectification for an Operator Always investigate the failure symptoms fully, prior to taking remedial action. Fault diagnosis for the equipment Operator is limited to the following tasks, since the Operator is not expected to remove the covers of the equipment or handle the cards: 1. Monitor equipment status using the display screen error messages. 2. Check the front panel Power and Alarm LEDs. 3. Check the DSNG Codec on-card status LEDs. ALL green LEDs should be lit to indicate connected power supply. If any red LEDs are lit then refer to that card’s section in Chapter 4, Equipment Description for a description of the LED function. 4. Replace external video, audio, data and power sources and cables by substitution to check their performance. 5. Confirm the equipment hardware configuration is suitable for the purpose and has been correctly installed and connected-up Reconfigure / reconnect as necessary. 6. Confirm that inappropriate Operator action is not causing the problem, and that the equipment software set-up, via the display screens, is capable of performing the task being asked of it. Change setup parameters as necessary. 7. Perform self-tests using the built-in facilities provided by the Diagnostics screens as necessary. 8. Replace fuse in the power connector at the rear panel. Page 5-6 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Preventive Maintenance and Fault-finding 9. Switch-off the equipment if it becomes unusable, or to protect it from further damage. 10. Call a trained and approved Service Engineer, or contact Customer Support) for further troubleshooting, or to replace an internal component or card. NOTE... The DSNG Codec must be connected to the monitor IRD in order to carry out tests in isolation. 5.2.3 Error Reporting Categories of Error Equipment status is monitored continuously by the Multiplexer / Baseband Modulator Card, and error messages are displayed on the Front Panel (and transmitted via the remote interface) in the event of a fault, or if poor operating procedure results in equipment capacity being exceeded. Relay contacts are also provided. Three categories of error may be indicated: 1. FATAL - Errors of a serious nature requiring transmission to be terminated immediately to prevent possible damage to other equipment. The equipment will attempt to turn off the IF output automatically but may not be successful due to the nature of the fault. When a FATAL error is indicated, the IF output should be checked and, if necessary, turned off manually. Fatal failures trigger both the Alarm and Fail relays and cause the Front Panel Alarm LED to be lit. 2. FAIL - Errors of a serious nature which may stop the equipment from working successfully, but present no danger to other equipment. Failures cause both the Alarm and Fail relays to be triggered and the Alarm LED to be lit. 3. ALARM - Errors of a less serious nature which may or may not prevent the equipment from working successfully. Alarms cause the Alarm relay only to be triggered and the Alarm LED to be lit. Alarm and Fail Relays Alarm and Fail relays are located on the Multiplexer / Baseband Modulator Card and are switched in response to detected error conditions. Relay contacts are available at the rear panel RESET / STATUS connector (see Chapter 2, Installation for connector details) to enable the equipment status to be monitored from a remote location. Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Page 5-7 Preventive Maintenance and Fault-finding Error Masking and Selection Any errors associated with the IF modulated output are classified as fatal failures and cannot be masked (disabled). Errors associated with multiplexing can be either alarms or failures depending on the nature of the error, and cannot be masked. Errors associated with the audio channels, data channels and the IRD can be set as alarms or failures or masked by the user using the Setup / System / Alarm/Fail Relays option. This option controls the relay contacts as well as the reporting of error messages on the Front Panel. Video errors can be either masked or enabled; when enabled, the nature of the fault determines whether an alarm or failure is appropriate. See Table 5.1 for details. Error Messages Whenever an error occurs the current display is replaced by an error message display. A typical error message is shown in Figure 6.1. FATAL IF Modulator Comms Failure Clear to Exit Category of error (FATAL/FAIL/ALARM) General area or function affected Specific problem Operator instructions Figure 5.1: Typical Error Message Error messages are accompanied by a beeper. After several seconds (2 to 3) the beeper is switched off automatically, and the screen cleared. Press Clear to remove both the beep and the screen immediately; the front panel Alarm LED will remain lit. To view this message again, and any other current error messages, go to the Diagnostics / Display Errors screen. Table 6.1 lists the error messages which an Operator is likely to encounter, and the action which should be taken.

Unplug the power connector from the Codec and try it in another piece of equipment. Does it work?. The problems lies within the Codec. Proceed to next step. The problem lies with either the cable itself, or with the fuse in the plug. Replace the fuse or try substitute another cable. 5 Check PSU Module and Fuse. Ensure the power connector is unplugged. Remove the fuse from the rear panel connector and inspect it. Has the fuse blown? Replace the fuse with one of the correct type and rating (see Chapter 2, Installation). If the PSU still does not work, unplug the power cable and call a Service Engineer. Possible problem with the PSU Module, call a Service Engineer. NOTE... The PSU contains over-temperature sensing circuitry which will shut down the DSNG Codec in the event of a problem (see Fan(s) Not Working/Overheating). Rear Panel DC Supply LED(s) Unlit If all the green LEDs at the left-hand side of the rear panel are unlit, troubleshoot as for Power LED Unlit. If the front panel Alarm LED is displayed, accompanied by an error message, then troubleshoot in accordance with the message (see Error Messages). If one or more of the d.c. supply LEDs is unlit, call a Service Engineer to check the continuity of the d.c. supply from the PSU Module to the card(s), and to check that the card(s) is (are) seated properly in the Backplane connector. Alarm LED Unlit when Alarm Occurs If front panel Alarm LED is not lit when an alarm condition is reported on the front panel, then call a Service Engineer to check the LED signal path continuity. NOTE... Some card alarm LEDs do not generate a unit fault condition. Page 5-18 Instruction Manual: Digital Satellite News Gathering Coder/Decoder ST.TM.E5910.5 Preventive Maintenance and Fault-finding Fan(s) Not Working/Overheating Cooling fans are operated in two banks of three. At very low temperatures (below 0°C), all the fans are off; at cold temperatures (between 0°C and 20°C), three fans are off, and at normal / high temperatures (above 20°C), all six fans are on. If the front panel Status / System screen displays indicates an overtemperature or fans not working warning, or if the cooling fans are not rotating or in the event of other overheating problems, troubleshoot as detailed in Table 5.6. CAUTION... Failure to ensure a free air flow around the unit may cause overheating. This may be detected by the PSU and trigger an automatic shut-down. The PSU will not reset until the temperature is within normal operational limits. Table 5.6: Fans Troubleshooting Step Action If Result of Action is Yes… If Result of Action is No… 1 Check Panels. All panels must be fitted to the enclosure for normal operation, to ensure correct air-flow around the enclosure. Are the panels fitted? Proceed to next step. Ensure missing panel(s) are fitted and secured in position. 2 Check Fan Rotation. Inspect the fans located at the sides of the enclosure. Are the fans rotating as expected (see text above)? Check that the Codec has been installed with sufficient space allowed for air flow (see Chapter 2, Installation). If the ambient air is too hot, additional cooling may be required. Possible break in the dc supply from the PSU Module to the suspect fan(s).
