7.8.1
The real time video interface consists of two bidirectional 8-bit wide ports transporting colour difference samples and
luminance samples in a byte sequential manner. Each of the two video ports (A and B) has its own clock pin, pixel
qualifier and horizontal and vertical sync signal pin. The sync signal can be optionally coded in SAV and EAV codes
according to the D1 standard (SMPTE125M or CCIR 656). The two 8-bit ports can be combined to form a single 16-bit
wide YUV port to be compatible to the DMSD2 output format.
