Chapter 3: Operation
An audio group cannot be divided. In Append embedding, the audio group is
always added following the last block in the ADS. If there is not enough room
to append the audio group following the last block of auxiliary data or audio in
the ADS, the attempt will result in an error, as shown in
.
Figure 3-6. Append Embedding Mode Returns Error When Auxiliary Data Exists in all Audio Groups
Overwrite Embedding
When you select Overwrite embedding, the module attempts to overwrite any
existing audio data and control packets of the same group number with the new
audio data. This setting is valid only if the audio group to be embedded already
exists. If the new sample distribution does not exactly match the existing audio
data packet sample distribution, the embedder will mark some audio data
packets for deletion (DID word will be set to 180h).
Note
To avoid sample distribution issues, activate the ADS Clean feature (see
“ADS Clean Parameter” on page 39
When you attempt Overwrite embedding and there is no previous audio (as in
), it will return an error because there is nothing to overwrite.
