Audio Embedding Errors
Table 3-2 describes G1-2AppErr and G1-2OvrWtErr audio
embedding errors.
To avoid embedding errors, follow these guidelines:
• Set the embedding mode to Auto . If the group is present, it will be
overwritten; if it is not present, it will be appended. The overwrite
and append errors are actually warnings that the desired operation is
not being performed.
• In SD-SDI mode do not overwrite embedded groups of 20-bit audio
samples with groups of 24-bit audio samples. The required
extended data packet information appended to that group may
overwrite a pre-existing audio group. For 24-bit audio embedding,
use the
ADS Clean feature provided.
Audio Output Channel Status (OutxxStat)
Table 3-3 describes the three parameter options for audio output
channel level status.
Table 3-2. Audio Embedding Error Descriptions
Error Description
G1-2AppErr 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 will not embed another audio
data and control packet of the same audio group, as this
will result in incorrect audio sample distribution.
G1-2OvrWtErr 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
Table 3-3. Audio Output Channel Level Status Options
Options Description
Peak Audio output level has reached a level of 0 dBFS.
Silence Audio output level is lower than -96 dBFS.
Normal Audio output level is between the Peak and Silence
threshold levels.
