The IYU1 format is a 12 bit format used in mode 2 of the IEEE 1394 Digital Camera 1.04 spec ("1394-based Digital Camera Specification, Version 1.04, August 9, 1996", page 14.). The format, a duplicate of Y411, is YUV (4:1:1) according to the following pattern:
Byte | 0 | 1 | 2 | 3 | 4 | 5 |
Sample | U(K+0) | Y(K+0) | Y(K+1) | V(K+0) | Y(K+2) | Y(K+3) |
Horizontal | Vertical | |
Y Sample Period | 1 | 1 |
V Sample Period | 4 | 1 |
U Sample Period | 4 | 1 |
