The GS1503B can be configured to delete the embedded ancillary data packets,
after demultiplexing. There are two modes for 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.
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.
