Figure 3-8 shows how overwrite embedding appears in the ancillary data space when there
is auxiliary data where Group 1 should be inserted.

Figure 3-9 shows how overwrite embedding appears in the ancillary data space when there
is pre-existing Group 1 audio. This operation is successful.

Table 3-4 describes Group ( 1–4 ) Append Embedding Error and Group ( 1–4 ) Overwrite
Embed Error audio embedding errors (also see page 61).
To avoid embedding errors, follow these guidelines:

Table 3-4 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 results 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.
