5.10 Ancillary Data Deletion
The GS1503B can be configured to delete the embedded ancillary data packets, after
demultiplexing. There are two modes for ancillary data deletion.
5.10.1 Entire Ancillary Data Deletion
When the ANCI external pin or ANCI bit 1 of Host Interface register 040h is set HIGH, all
ancillary data packets in both the Luma and Chroma channel of the input video stream
are deleted. The data is replaced with blanking values 040h in the Luma channel and
200h in the Chroma channel. The DEL_SEL bit 0 of Host Interface register 040h must be
set LOW.
5.10.2 Audio Group Designation Ancillary Data Deletion
When the ANCI bit 1 of Host Interface register 040h is set HIGH, and DEL_SEL bit 0 of
Host Interface register 040h is HIGH, only audio data and control packets which are
designated in Host Interface registers 041h will be deleted. To delete the arbitrary data
packets, the corresponding DID must be set in the NDID[7:0] Host Interface register
042h.
