The embedded audio packets are inserted into the video signal together with the control
packets and any other packets that were present in the original video signal. The video is
serialized and output through the cable and laser drivers. The audio signals are taken from
the outputs of the audio router.
1.3 Data signal
The data signal is transported using the User bits in one of the embedded audio streams.
De-embedded data is output on the RS485 output. Data received at the R422 input is
embedded into the output video. The configuration sets the audio source containing the data
signal to de-embed, the data format to be received on the backplane connector and which
audio output signal to embed data into.
