The difference between BT656 and BT1120

BT656: One clock line, 8 data lines.
BT1120: One clock line, 16 data lines.
Two BT656 can form a BT1120.
Since the video format output by HiSilicon HI3536DV200 is BT1120, there is no horizontal and vertical synchronization signal, and the horizontal and vertical synchronization signal is embedded in the data, so GS2972 needs to be configured in data synchronization mode.
