Audio Routing

The RX8000 Receiver supports the following routing of audio signals:
•
•
•
•
When the input signal is STEREO, the Audio digital output format will always be
STEREO.
Where a dual mono service is available, it is possible to configure the output as
MIXED TO BOTH, LEFT TO BOTH and RIGHT TO BOTH.
B.3.4

Lip Sync

The audio at the output remains synchronous to the decoded video by default (i.e.
where both video and audio streams are available from the same service). In such
circumstances the video and audio streams share the same PCR.
The lip sync error (delay from presentation of video until presentation of audio)
introduced by the Receiver is in the range of ±2 ms.
The lip sync delay between different stereo pairs is ±2 ms because the PTS will be
presented independently for each pair.
