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 2.0 and CD-I FMV specifications  
Real-time decompression and synchronization of MPEG bitstreams with SIF resolution video and two  
channels of Layer 1 or Layer 2 audio  
·
·
·
·
·
·
·
Automatic frame rate conversion during A/V playback  
Decompression of high resolution still pictures(704x480(NTSC) or 704x576(PAL))  
Optional horizontal and vertical interpolation for image quality enhancement  
Automatic IO address setup  
Fade in/out control and brightness adjustment  
RGB(24-bit) and YCbCr(24-bit, 16-bit, 8-bit) video output formats  
Support NTSC/PAL interlace/non-interlace and VGA progressive display with programmable video timing
