Append Embedding
When you select
Append
embedding, the FS1 and XD1 attempt to insert the audio data and control
packets immediately following the last existing data/control packet in the horizontal ancillary data space
(ADS). Append embedding is only valid if the audio group to be embedded does not already exist.
The figure below shows how append embedding appears in the ancillary data space when there is no
previous audio or other data.
Figure 41:
Append Embedding Mode; Adding Group 1 When No Other Data is Present
When ancillary data exists in the ancillary data space, appended audio appears following that data.
Figure 42:
Append Embedding Mode; Adding Group 1 When Ancillary Data is Present
If you attempt to insert audio into Group 1 when Group 1 audio data already exists in the ancillary data
space, an error is returned, as shown below.
