2.9.2 Arbitrary Data Demultiplexing in Host Interface Mode
To select this mode, set ARBITMODE bit 0 in Host Interface
register 050h HIGH. In this mode, the DID, SDID, DC and
User
corresponding Host Interface registers. Set the video line
number for field 1 and field 2 from which the arbitrary data

2.10 ANCILLARY DATA DELETION
The GS1503 can be configured to delete the embedded
ancillary data packets, after demultiplexing. There are two
modes for ancillary data deletion.
2.10.1 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.

registers respectively. The arbitrary data packet is
demultiplexed when the ARBITON bit 1 in Host Interface
register 050h is set HIGH. ARBITON should be set LOW
when reading the arbitrary data packet User Data Words
