8.2.1
RGB-TO-(Y-C
B-CR) MATRIX
The matrix converts the RGB signals from the analog-to-digital converters/downsamplers to the Y-CB-CR representation.
The input and output word widths are 9 bits. The matrix has a gain factor of 1. The block provides a delay compensated
bypass for component input signals.
The matrix is represented by the following equations:
Y = 0.299
× R + 0.587 × G + 0.114 × B
CB = 0.5772 × (B Y)
CR = 0.7296 × (R Y)
