They are suitable for a portable DVD or VCD player. They convert ITU-R.BT601/656 standard 8-
bit parallel data into analog composite video, S-Video or analog component signals Y/Cb/Cr in
NTSC and PAL formats.
AK8812 and AK8811 support Macrovision Copy Protection Rev.7.1(only AK8812), Closed
captioning and Video Blanking ID(CGMS). These functions are controlled by high-speed I
interface.
