GENERAL DESCRIPTION
W9922PF is a powerful MPEG-2 video decoder which
performs real-time decompression of ISO/IEC 13818-2
MPEG-2 and 11172-2 MPEG-1 video streams. The
processor is designed for applications of PC multimedia
systems to provide an extensive video processing
capabilities and interfaces with PC graphic subsystems.
It also supports the decoding capabilities of VCD, CVD,
SVCD and DVD.
FEATURES
• Decodes MPEG-2 at MP@ML and MPEG1 video
streams
• Fully supports multiple CD formats : Karaoke CD,
VCD, CVD, SVCD, CD-I and DVD titles
• Built-in PCI and VMI / VIP bus interfaces
• Directs interface to 1Mx16-bit SDRAM
• Supports Video Scaling
• Automatic frame rate conversion
• Provides RGB and YCbCr video output formats
• Decodes SVCD/DVD compliant sub-picture and
highlights
• Supports 16:9 and 4:3 aspect ratio by pan&scan and
letter box conversion
• Supports audio/video synchronization
• Fully 3.3V operation
• Standard 160-pin PQFP
PC SVCD / DVD SOLUTION
S/W Audio Decoder
Software audio decoder can real-time decompress
MPEG-1 (ISO/IEC 11172) and MPEG-2 (ISO/IEC
13818) audio streams; its inputs can be PCM audio
stream, Dolby
digital AC-3 2 or 5.1 channel encoded
up to 48 Khz sampling rate. As to outputs, it can be
Dolby
digital AC-3 2 channel stereo or Pro-Logic
decoded stream. Software audio decoder supports
Multi-Audio , Muti-Language and high quality Dolby
Certification.
S/W VCD / SVCD PBC and DVD Navigator
Software provides VCD 2.0 and SVCD PBC ( Play Bac
k
Control function ). Software DVD Navigator provide
s
drivers for MCI, supports DVD decryption an
d
regionalization code, and conforms to the VCD, SVC
D
and DVD Specifications.
Cost-Effective H/W Configurations
In PCI add-in applications, W9922PF can be dire
c
connected to PCI bus and receives various compres
s
bitstreams and operating commands via the host interfa
