Notes
ADS Clean
In all modes of operation (Framesync/Delay/Demux-only mode), ADS Clean set to Yes wipes out all
HANC data with the exception of EDH (SD only).
When a channel is operated in Framesync mode or if a board without a Framesync license (Demux-only)
has the ingested SDI signal already locked to the reference signal applied to the board, the Audio
Embedder re-populates the HANC space with Audio data coming from the Audio processor. In order for
the Audio Embedder to re-populate empty HANC space, the group embedding mode has to be set to
either ‘Auto’ or ‘Append’. Overwrite only applies if there is ’something’ to overwrite.
When operating a channel in Framesync mode, use ADS Clean with extra caution because it wipes out
any non-PCM Audio data (Dolby E/D) which is lost forever. Non-PCM Audio data is not re-embedded by
the Audio Embedder, since all non-PCM data bypasses the Audio processor altogether. With ADS Clean
set to ‘Yes’, non-PCM Audio data will no longer appear in the outgoing SDI stream or show up in the
TDM stream going to the Audio crosspoint. To counter this, a new Audio Synchronizer IP is required
where the clock domain transfer of Dolby data (by dropping or repeating a frame worth of Dolby data)
happens in the Audio Synchronizer’s memory rather than in the Video Frame-synchronizer’s memory.
