Description

The MC44724 and MC44725 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 or R/G/B in PAL and NTSC formats. MC44724 and MC44725 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.

MC44724 and MC44725 are specifically designed for digital satellite, digital cable decoders and multimedia terminals.
