Append Embedding
When you select Append embedding, the HMX6803+ and OP+HMX+
attempts 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.
Figure 3-1 shows how append embedding will appear in the ancillary data space
when there is no previous audio or other data.
Figure 3-1. In Append Embedding Mode, Adding Group 1 When No Other Data is Present
When auxiliary data exists in the ancillary data space, appended audio appears
following that data, as shown in
Figure 3-2.
Figure 3-2. In Append Embedding Mode, Adding Group 1 When Auxiliary Data is Present
Auto Attempts first to overwrite existing audio data and control
packets of the same audio group number; failing that, it
appends the new audio data and control packets
immediately following the last existing audio data/control
packet (refer to the Audio Group (1–4) Exists parameters
on
page 51 to determine what audio groups are already
present in the incoming SDI signal)
