UNCTIONALITY
The TS Router block receives input streams from one of the available sources,
for example: QPSK, MPEG-over-IP IN, ASI IN, and routes the selected input to
the Master and Slave decoders. Each decoder decodes one program from the
input stream, routed by the TS router block, and provides decoded digital audio
and video streams. These streams are provided to the Video Router block that
would route them to the relevant outputs as well as to the Analog Video Output.
The Analog Video Output receives a Digital Video, converts the digital video into
analog video, and outputs the analog video. The Analog and Digital Audio Output
component outputs the digital and analog audio.
