GS1582 Data Sheet
40117 - 1 November 2007
48 of 114
When the CASCADE bit is set HIGH, the GS1582 defaults to audio groups 3 and
4, where Ain_1/2 and Ain_3/4 are multiplexed with audio group 3 DID, and Ain_5/6
and Ain_7/8 with audio group 4 DID.
NOTE: If IDA and IDB are set to the same value, these bits will automatically revert
to their default values.
Any other configurations can be programmed for the audio groups as required.
4.7.11 Audio Group Replacement
Audio group replacement mode allows the multiplexing of new audio groups, whilst
replacing existing embedded audio with the same group DID. All other embedded
audio groups will remain in the video stream. Up to two groups of audio (and
extended audio for SD formats) can be replaced at once.
The first function performed by the GS1582 is deleting the audio group or groups
to be replaced. The next step is removing and storing any other audio packets that
are to be preserved. The final step is to embed the new and stored audio data
packets so they are contiguous from the EAV (for HD formats, they will be
contiguous after the line CRC words). See
Figure 4-17
