Introduction 1 ◆ The STELLAR MPEG-2 Decoder General description The STELLAR MPEG-2 Decoder is intended for professional decoding of a single program comprising one video signal with up to two stereo audio channels. Programs can be decoded according to MP@ML or 4:2:2P@ML. The STELLAR can be set up and configured individually for specific professional contribution and distribution applications.
1 The output bit rate can be set between 1.0 and 9 2Mbit/s. The SMPTE 310M output is a 19.39 Mbit/s data stream. SDI genlock The decoder optionally provides a black and burst reference input for genlocking of the SDI video output. The line frequency of the composite video output is also locked to the external reference but not the SCH phase.
Introduction 1 VBI signal Recovered from the TS Inserted locally in the decoder PAL NTS C VITC Time coded data is recovered no from the transport stream signal and inserted in the composite or embedded in the SDI output. yes yes IDS/VPS The IDS/VPS signal is recovno ered from the transport stream and inserted in the composite or embedded in the SDI output. yes no GCR no A ghost cancellayes tion reference signal (GCR) may be inserted in the composite output of the decoder.
1 ◆ Application examples Distribution The STELLAR can be used for distribution to analog VHF/UHF transmitters and to cable head-ends. The decoder includes high-quality composite outputs with VBI support, and features VITS and GCR insertion, dedicated to analog feeds. The MP@ML is the typical choice for this application, and it allows the stream to be used for simulcast of digital TV. 4:2:2P@ML provides increased quality overhead and allows transmission of anti-PAL signals, but the delay is higher.
1 Introduction The following table shows the transcoding possibilities from Audio input to Audio output. Audio input ◆ Audio output Digital audio AES/EBU Analog Audio, Analog audio Digital audio AES/EBU Embedded audio in the SDI Audio embedded in the SDI Video interfaces Video output modules The STELLAR has a composite video output and/or a 270 Mbit/s SDI formatted video output.
1 ◆ Audio and data interfaces Audio output modules The STELLAR has as standard one analog stereo or digital AES/EBU output. The analog output provides a balanced output signal. As an option the following output module can be installed: • one additional analog stereo or digital AES/EBU output. Both audio channels which are to be decoded must be part of the same program.
Introduction 1 ◆ Network and TS interfaces Network/TS interfaces The following network/TS interfaces can be ordered for the STELLAR: • • • • • • • • Stellar Dual input E1 input E3 input DS3 input SPI input ASI input V.35 input ASI restamping output SMPTE 310M output The input interfaces (apart from the V.35 input) provide a dual input facility supporting transmission path duplication.
1 ASI input When installed with the ASI input the STELLAR automatically detects the transport stream format as 188 or 204 bytes packet lengths and performs RS (204,188) error correction when FEC is included in the transport stream. ASI restamping output When installed with the ASI restamping output option the STELLAR can relay the full transport stream recovered from the input. The output bit rate of the STELLAR can be set from 1 to 92 Mbit/s.

If you try to install a driver with a product version different from the COPERNICUS server software product version, ROSA will refuse to install the driver. To install an updated version of the driver with the same product version, follow the above procedure. In this case ROSA will detect the existing driver and will ask you to confirm to replace the existing driver.
4 ◆ Setting the STELLAR addresses in ROSA/COPERNICUS Addresses A STELLAR has two addresses: • One address for the unit type, for the STELLAR 51 (hexadecimal), so ROSA recognizes the type of unit connected, and • one unique remote address, so ROSA can communicate with each single unit. To give the STELLAR a unique remote address To give the STELLAR a unique remote address do as follows: 1. Connect the STELLAR via its remote RS-485 port to the serial port of the COPERNICUS server and power it up. 2.
Setup and monitoring 4 ◆ Adding a unit to ROSA Background When COPERNICUS detects a newly attached RCDS-compatible unit, it marks this unit as being new. It can be a new unit, a replacement for a defective one or a unit that was removed but is now connected again.

Appendix C Error Detection and Handling (EDH) General on EDH EDH control commands in the STELLAR C C-2 C-3 C-1
Error Detection and Handling (EDH) C ◆ General on EDH Reference The POLARIS and STELLAR support EDH (Error Detection and Handling) for 625 lines SDI according to SMPTE RP 165. Background EDH is used for recognizing errors and inaccuracies in the SDI signal. You may use EDH as a tool to help pinpointing sources of errors in a chain of SDI equipment, including video codecs with SDI interfaces. Conceptually, the POLARIS and the STELLAR is one EDH entity.
C ◆ EDH control commands in the STELLAR General EDH is as default enabled in the STELLAR so that it outputs EDH data received from the encoder. EDH commands You may, however, control EDH in the STELLAR by using the ROSA control and management system where the following modes exist: Parameter Explanation OFF The STELLAR does not analyze the EDH data and does not output EDH on the SDI output. Transparent The received EDH data is retransmitted without changes.
