luma-chroma displacement. The adjustment range is -20 to 20 in steps of 2 luma
clocks.
At the input picture edge, zero chroma is shifted into the active picture area. If the
ARC is set to show less than the full width of the input picture, valid input picture
chroma is shifted into the output picture area.
