4.8.2.2 Level B Signals:
For Level B inputs, the GS2962 does not extract the SMPTE 352M packets from the
parallel input. The only source of SMPTE 352M packets in Level B mode, to be used for
format detection and for embedding in the output data streams, is from the user
programmed registers in the host interface.
4.8.3 ANC Data Blanking
The GS2962 can blank the video input data during the H and V blanking periods. This
function will be enabled by setting the ANC_BLANK pin LOW.
This function is only available when the device is operating in SMPTE mode
(SMPTE_BYPASS = HIGH).
In this mode, input video data in the horizontal and vertical blanking periods will be
replaced by SMPTE compliant blanking values.
The blanking function will operate only on the video input signal and will remove all
ancillary data already embedded in the input video stream.
