MPEG-2 VIDEO Encoder/Decoder

The CS92210 is a real time MPEG-2 video encoder and decoder (CODEC) that fully complies with the ISO/IEC-13818 Main Profile@Main Level (MP@ML) format, Simple Profile@ Main Level (SP@ML), and Main Profile @ Low Level (MP@LL).

In encode mode, the CS92210 accepts digital video in ITU-R BT.601 (CCIR-601) or ITU-R BT.656 (CCIR-656) format. The input is filtered and then encoded to produce compressed bitstreams in MPEG-2 MP@ML syntax. In decode mode, CS92210 accepts an MPEG bitstream, decodes it, and then filters the video output to produce either ITU-R BT.601 or ITU-R BT.656 format digital video. Designed for flexibility, the CS92210’s video interface supports multiple video formats, resolutions, and frame rates including NTSC, PAL, and FILM.
