By enabling the
ADS Clean
parameter, you will remove all ancillary data packets in the Horizontal
Ancillary data space (HANC). If there are data packets other than audio in the HANC space (for example,
RP196 or SMPTE-12M-2 ATC HANC timecode), this data will also be removed along with the audio data.
Therefore, before enabling the
ADS Clean
parameter, ensure there are no pre-existing non-audio data
packets in the HANC space. To overwrite pre-existing audio groups instead of wiping out pre-existing
audio data, use the
Overwrite
embedding feature (page 57 (see "Overwrite Embedding" on page 70)).
Embedding Errors
During the embedding operation, errors may arise for the following reasons:
•
An attempt is made to append a group when it is already present
•
An attempt is made to overwrite a group when it is not present
•
An attempt is made to overwrite a group composed of 20-bit audio samples with a group composed
of 24-bit audio samples
•
There is an overflow condition in the ancillary data space
•
There is an overflow or underflow of the internal buffer
Preventing 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 warnings that the desired operation is not
being performed.
•
Don’t 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.
•
Use the
ADS Clean
feature to avoid ADS overflow situations
Note
: The
ADS Clean
feature has limitations. See page 58 (see "ADS Clean" on page 71) for details.
