Rohde & Schwarz presents network operator solution for entire ISDB-TB transmission chain

NAB 2014, LAS VEGAS, USA: Rohde & Schwarz now offers ISDB-TB network operators a complete single-source equipment suite for setting up transmission chains.

Together, the R&S AVHE100 headend and the R&S AVG050 remultiplexer with integrated BTS compressor/decompressor provide a compact solution for encoding and multiplexing in ISDB-TB networks.

The R&S AVHE100 encodes and multiplexes programs' video and audio signals in line with the ISDB-TB standard. Other optional functions include encryption, monitoring and an innovative redundancy system (R&S CrossFlowIP).

The output data stream is DVB-compliant and can be fed directly to transmitter locations via satellite. A downstream R&S AVG050 remultiplexer can be used to convert this data stream into a compressed or uncompressed broadcast transport stream (BTS), which is forwarded to transmitter locations via satellite or terrestrial networks.

Transmitting the signal via DVB-S2 or compressed BTS saves network operators transponder bandwidth. It is also possible to receive programs direct-to-home without any additional technical effort.

The space-saving R&S AVG050, which is installed at the transmitter location, handles various tasks in a single box. Its integrated DVB-S receiver allows it to receive and demodulate a satellite's MPEG-2 input transport streams and generate a BTS.

The gateway can also convert transport streams fed in via IP or ASI into a BTS. For decrypting encrypted content, the R&S AVG050 features two common interface (CI) slots for conditional access (CA) modules or an integrated BISS decoder, enabling it to simultaneously support various encryption methods.
