The MC44722 and MC44723 are Digital Video Encoders (DVE).
They convert ITU-601/656 standard 4:2:2 Bit-Paralellel data into
analog composite video, S-Video or Y/Cb/Cr in PAL and NTSC
formats. They accept the multiplexed ((CB,Y,CR)Y) signals from
digital sources such as MPEG decoders and can act as a sync
generator master. All video processing is done digitally and
requires no external adjustment.
Specifically designed for digital satellite, digital cable decoders
and multimedia terminals.
