•

Capture a frame from an external video decoder device

•

Support ITU–R BT.656 or VESA Video Interface Port (VIP) format of YCrCb 4:2:2

• Data format: C

B, Y, CR, Y, etc

• Control structure: FF, 00, 00, XY

XY contains the video timing reference code

XY = {1, F, V, H, P3, P2, P1, P0}, where

F = Field

V = Vertical

H = Horizontal (0 = SAV, 1 = EAV)

P3, P2, P1, P0 = error protection bits, with P3 = V xor H, P2 = F xor H, P1= F xor V, P0 = F

xor V xor H
