Embedded 1-2 DID Option
This option defines the DID to be de-embedded to obtain the audio source
for SDI Embedded 1 and SDI Embedded 2. If this is set to 1024, then the
default DID will be used. Refer to Annex F, Audio Modes for information
about DIDs.

Embedded 3-4 DID Option
This option defines the DID to be de-embedded to obtain the audio source
for SDI Embedded 3 and SDI Embedded 4. If this is set to 1024, then the
default DID will be used. Refer to Annex F, Audio Modes for information
about DIDs.
Audio PID Option
This option 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.
Component Tag Option
This item defines the optional component tag to be assigned to this audio
stream.
PCR On Audio PID Option
This option controls whether PCR should be signalled on the audio PID.
This may be necessary if an audio only service is being generated. The
default setting is Off.
OP Digital Loss
This option controls behaviour digital audio is not locked.
