The CS92288 is a single chip, real time MPEG-2 audio/video
encoder/decoder
multiplexor/demultiplexor and on-screen display (OSD) feature. The
CS92288 codec encodes and decodes both ISO/IEC 13818 Main
Level @ Main Profile (ML@MP), Simple Profile @ Main Level
(SP@ML), Main Profile @ Low Level (MP@LL), and ISO/IEC 11172
(MPEG-1) video bitstreams as well as MPEG audio, and Dolby Digital
(AC-3).
In encode mode, the CS92288 produces MPEG-compliant audio and
video elementary bit streams, program bit streams, as well as
transport streams for broadcast and set-top box applications. For
additional flexibility, the CS92288 accepts video in either the ITU-R
BT.656 (CCIR-656) or ITU-R BT.601 (CCIR-601) format. Audio is
input in the Linear PCM format. In decode mode, the CS92288 can
accept MPEG transport streams, program bit streams, as well as
audio and video elementary streams. Video can be output in either
the CCIR-656 or 601 CCIR-601 format. Audio is output in the Linear
PCM format.
For applications requiring on screen displays, the CS92288 OSD
feature supports both text and graphics.
