MPEG-2 Decoder Cores Rev Up Interactive Multi-Channel Streaming June 2002 Issue Published Date: June 01, 2002
New multimedia IP cores in the form of MPEG-2 transport stream multiplexing and multi-stream decoders have been developed for next-generation, high-speed digital video ASICs and SoCs. The CS6804 MPEG-2 demux can simultaneously handle four transport streams from independent sources, with up to four video and four audio packetized elementary streams (PESs) per input. The CS6652 and CS6654 MPEG-2 video decoders can perform simultaneous decoding of up to two or four video elementary streams (ISO/IEC 13818-2 compliant), supporting both MP@ML and 4:2:2P@ML. The decoders can be configured to handle a single elementary stream at 4:2:2P@HL, and optional "lite" versions are available for decoding and storing only essential parameters from the MPEG-2 video stream. The CS6804 transport demux can achieve maximum throughput rates of 800 Mbps, with single channel rates up to 300 Mbps. The CS6652 and CS6654 decoders, in turn, can process 300 Mbps to reportedly cover the most demanding high-definition applications.
