W9925PF MPEG-1 A/V SYSTEM DECODER GENERAL DESCRIPTION The W9925PF is a high-performance single-chip MPEG-1 decoder. It performs real-time decompression of ISO/IEC-11172 MPEG (Moving Picture Experts Group) streams, including system layer, audio and video data. This chip incorporates an 8-bit host interface and a CD interface that make it an easy use in standalone applications.
