Introduction
The multiplexor receives a satellite transponder in any of DVBS (QPSK) or
DVBS2 (QPSK or 8PSK) modulation formats, and demodulates it to obtain a
transport stream packet.
Then, the transport stream packet is modulated, either in QAM format (Ref.
564101) or COFDM format (564201), and converted to the output channel
by means of an agile up-converter.
Additionally, it incorporates a Common Interface slot for inserting a
conditional access module (CAM) that permits the unscrambling of
services.
To configure the multiplexer operating parameters (input frequency,
output channel, modulation format and adaptation of services mainly) can
be used the universal programming unit (ref. 7234) or the TSuite software.
