MPEG-2 Video Encoder/Decoder

The CS92210 is a real-time, MPEG-2 video encoder/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) making it an ideal platform for MPEG applications.

In encode mode, the CS92210 accepts digital video in ITU-R BT.601 (CCIR-601) or ITU-R BT.656 (CCIR-656) format. This 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. The CS92210's versatile time-stamp feature enables flexible muxing of audio and video elementary bit streams. In addition, the CS92210 can encode and decode bitstreams in both the VCD and SVCD formats.

The algorithmic and architectural innovations of the CS92210 enable a high degree of integration and video quality over the widest range of bit rates. It also eases system design by interfacing to a variety of commodity components such as video decoders, encoders, and memories.
