B.3.6
Dual Mono
Where a dual mono service is available (i.e. stream 1 and stream 2 sharing
the same PID), it is possible to configure the output as follows:
·
Stream 1 on both left and right channels
·
Stream 2 on both left and right channels
·
Stream 1 on left channel, and stream 2 on right channel
B.3.7
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 ±2ms.
The lip sync delay between stereo pair 1 and 2 is ±2ms because the PTS
will be generated independently for each pair.
When using frame sync the lip sync error is –10 to +30ms due to audio
frame skip and repeats.
