Horizontal sync timing input configuration.
Set LOW when the H input timing is based
on active line blanking. Set HIGH when the
H input timing is based on the H bit of the
TRS words. See Figure 15.
SMPTE352M packet insertion. In HD mode,
inserts the 352M packet in the Y channel
only when the four VIDEO_FORMAT
registers are programmed with non-zero
values and when IOPROC_EN/DIS is HIGH
and SMPTE_BYPASS is HIGH. This bit must
be set LOW.
Illegal Code Re-mapping. Detection and
correction of illegal code words within the
active picture area (AP). Set HIGH to
disable. The IOPROC_EN/DIS pin and
SMPTE_BYPASS pin must be set HIGH.
Error Detection & Handling (EDH) Cyclical
Redundancy Check (CRC) error correction.
In SD mode the GS1532 will generate and
insert EDH packets. Set HIGH to disable.
The IOPROC_EN/DIS pin and
SMPTE_BYPASS pin must be set HIGH.
Ancillary Data Check-sum insertion. Set
HIGH to disable. The IOPROC_EN/DIS pin
and SMPTE_BYPASS pin must be set HIGH.
Y and C line based CRC insertion. In HD
mode, inserts line based CRC words in both
the Y and C channels. Set HIGH to disable
The IOPROC_EN/DIS pin and
SMPTE_BYPASS pin must be set HIGH.
Y and C line number insertion. In HD mode
set HIGH to disable. The IOPROC_EN/DIS
pin and SMPTE_BYPASS pin must be set
HIGH.
Timing Reference Signal Insertion. Only
occurs when IOPROC_EN/DIS is HIGH and
SMPTE_BYPASS is HIGH. This bit must be
set LOW.
