A single-chip MPEG-2 video, audio and system encoder [in CMOS]

MPEG-2 encoding of motion pictures requires intensive computation and high I/O bandwidth to compress and packetize the video and audio streams for storage or transmission. As such, MPEG-2 encoding has traditionally been implemented with separate chips for video compression, audio compression, and system encoding. Such multi-chip solutions increase the total cost of MPEG-2 encoding and have consequently limited its use to expensive professional applications. This single-chip MPEG-2 encoder integrates the video, audio, and system-level functionality for low-cost main profile at main level (MP@ML) encoding applications. Industry-standard interfaces reduce the total chip count and board space required for implementing PC-based and consumer-electronics applications.
