Audio Delay:
Set the delay to be applied to the
audio.
Max: 3540
Audio Delay in milliseconds.
This option is only available if the Auto Lip Sync option is set to Off.
Audio PID:
Sets the PID to be used for the
audio channel. In the event of a
PID clash, one of the PIDs will be
changed by the Encoder’s internal
checking algorithm.
To be DVB compliant the audio PID should not be less than 32. However it is
possible to set the PID to less than 32, but in the event of a PID clash the
Encoder’s internal checking algorithm will not resolve the conflict.
Auto Lip Sync
4
:
Controls whether the Encoder
automatically adjusts the audio
delay to maintain lip sync with the
video.
If the Encoder is being controlled via SNMP by a control system that has auto
lip sync functionality, then this should be set to off.
If the control equipment is a TT7000 System Manager, ensure that the Auto
Lip Sync option is turned on. The TT7000 does not have a lip sync function
therefore the Encoder has to provide this.
4
To ensure correct lip sync when working with linear or pre-encoded audio, use the option card M2/EOM2/AUDLIN2.
