AMD-55-DVB-S/S2 MODULATOR / MULTIPLEXER is a brand new DVB-S/S2 modulator/multiplexer designed for applications over satellite digital TV or MVDS in full compliance with DVB standard.
The AMD-55-DVB-S/S2 MODULATOR / MULTIPLEXER converts transponders included IP or ASI transport stream into QPSK/8PSK/16APSK/32APSK signal to transmit them in satellite or MVDS L-band Up-Converter.
DVB-S/S2 carrier from available up to 120 transport streams are multiplexed and generated. The internal processing allows the output of DVB signals in full HD resolution.
The device receives a data stream via Gigabit Ethernet or ASI. It can receive up to 120 transport streams from the TROPHY HeadEnd or from another IP sources included MPEG transport streams.
The AMD-55-DVB-S/S2 MODULATOR / MULTIPLEXER integrates all the mechanisms required to feed transmitter sites with ASI or IP streams in highly secure formats. MODULATOR include all the latest state-of-the art technological features, and Broadcasters are able now to take full advantage of this second generation Terrestrial Digital TV technology, and deploy techniques such as SISO/MISO and Multi-PLP layered modulation.
1.1. MAIN FUNCTIONS OF AMD-55-S/S2 MODULATOR / MULTIPLEXER:
