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.
The CS92210’s versatile time-stamp feature enables flexible muxing
of audio and video elementary bit streams. Also, 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 while still providing exceptional video
quality over the widest range of bit rates. Also, the CS92210
provides ease of system design by interfacing to a wide variety of
commodity components such as Philips video decoders and
encoders, Flash and SDRAM memories.
