Convert ITU-601/656 standard 4:2:2 Bit-Parallel data into analog composite video, S-Video or Y/Cb/Cr in PAL and NTSC formats.
The MC44722A and MC44723A are Digital Video Encoders (DVE). They convert ITU-601/656 standard 4:2:2 Bit-Parallel 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 generatorleader. All video processing is done digitally and requires no external adjustment. Specifically designed for digital satellite, digital cable decoders and multimedia terminals.
