DESCRIPTION
Control Signal Input. Used to enable or disable insertion of TRS
into the video streams. When TRS_INS is high, the device
inserts SMPTE 292M compliant TRS signals into the input LUMA
and CHROMA data streams based on the supplied HVF
signals. When TRS_INS is low, the device does not insert TRS
signals.
Control Signal Input. Used to enable or disable insertion of line
numbers into the video stream. When LN_INS is high, the
device inserts SMPTE 292M compliant line number information
into the LUMA and CHROMA channels. When LN_INS is low,
the device does not insert the line number information into the
LUMA and CHROMA channels. Line number insertion is only
available when user supplied external FVH data is used
(DET_TRS set LOW).
Control Signal Input. Used to enable or disable insertion of
CRCs into the video stream. When CRC_INS is high, the device
calculates and inserts line based CRCs. When CRC_INS is low,
this feature is disabled.
This pin must be connected to VDD for normal operation.

Input
Control Signal Input. This signal indicates the Horizontal
blanking period of the input video data stream. The device
inserts HDTV TRS based on the supplied HVF signals. Refer to
Figure 4 for required timing of H relative to LUMA
(DATA_IN[19:10]) and CHROMA (DATA_IN[9:0]).
Control Signal Input. This signal indicates the Vertical blanking
period of the input video data streams. Refer to Figure 4 for
required timing of V relative to LUMA (DATA_IN[19:10]) and
CHROMA (DATA_IN[9:0]).
