Chapter 3: Operation
Figure 3-8 shows how overwrite embedding will appear in the ancillary data
space when there is auxiliary data where Group 1 should be inserted.
Figure 3-8. Overwrite Embedding Mode When There is Auxiliary Data on Group 1
Figure 3-9 shows how overwrite embedding will appear in the ancillary data
space when there is pre-existing Group 1 audio. This operation is successful.

Audio Embedding Errors
Table 3-3 describes Group (1–4) Append Embedding Error and Group (1–4)
Overwrite Embed Error audio embedding errors (also see page 51).
To avoid embedding errors, follow these guidelines:
EAV
ADS before embedding
other
auxilliary data
A
other
auxilliary data
B
ADS after attempting to embed group 1
EAV

Table 3-3. Audio Embedding Error Descriptions
Error Description
Group (1–4)
Append
Embedding
Error
This error occurs if the embedder is set to Append mode
for a particular audio group, but that audio group already
exists in the incoming SDI signal.
In this case, the embedder does not embed another audio
data and control packet of the same audio group, as this
will result in incorrect audio sample distribution.
Group (1–4)
Overwrite
Embed Error
This error occurs if the embedder is set to Overwrite
mode for a particular audio group, but that audio group
does not exist in the incoming SDI signal
