Color-space Conversion in the Matrix
When the input pixels are in RGB, GBR, or color-index for-
mat and the CLUT is bypassed (TMC22191), the Matrix
remains enabled, converting RGB data to color-difference
format. When the input pixels are in 444 format
(YC
verts 422 to 444) is not active. When the input pixels are in
YC
color-difference values and the Matrix is inactive. In color-
index mode, the Matrix is active, converting the RGB CLUT
output data to color-difference values.
