Chrominance Upsampling Unit
Both 4:2:2 and 4:2:0 input formats are supported by the LCD module. In 4:2:2, the two chromi-
nance components are sampled at half the sample rate of the luminance. The horizontal
chrominance resolution is halved. When this input format is selected, the chrominance upsam-
pling unit uses two chrominances to interpolate the missing component.
In 4:2:0, Cr and Cb components are subsampled at a factor of two vertically and horizontally.
When this input mode is selected, the chrominance upsampling unit uses two and four chroma
components to generate the missing horizontal and vertical components.
