Overview
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.
FEATURES • High integration of MPEG system, audio and video decoding, video scan timing generation, and CD-ROM decoding functions • Applicable to ISO/IEC 11172 system streams, CD-DA data, and CD-ROM data • Fully supports Karaoke CD, Video CD 1.
1, Video CD 2.
