4.5 Video Data Processing
4.5.1 Video Signal Input Detection
The GS1503B will set the VIDEO_DET external pin HIGH when three consecutive TRS
are detected in the input video signal. Also, the VIDEO_DET bit of Host Interface register
000h is set HIGH.

4.5.2 Video Input CRC Error Detection
The GS1503B will set the CRC_ERR external pin HIGH when a CRC error is detected in
the input video signal. Also, the CRC_ERR bit 5 of Host Interface register 000h is set
HIGH. The number of CRC errors accumulated in one video frame can be read form
CRC_CNT[11:0] in Host Interface registers 006h and 007h.
