Annex B
B.3.3 | Audio Routing |
The RX8000 Receiver supports the following routing of audio signals:
•STEREO (Channel 1 left, Channel 2 right)
•MIXED TO BOTH (Channel 1 and 2 on left and right)
•LEFT TO BOTH (Channel 1 on left and right)
•RIGHT TO BOTH (Channel 2 on left and right)
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. |
