W9922PF

MPEG-2 VIDEO DECODER

GENERAL DESCRIPTION

S/W VCD / SVCD PBC and DVD Navigator

Software provides VCD 2.0 and SVCD PBC ( Play Back

Control function ). Software DVD Navigator provides

drivers for MCI, supports DVD decryption and

regionalization code, and conforms to the VCD, SVCD

and DVD Specifications.

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.

Cost-Effective H/W Configurations

In PCI add-in applications, W9922PF can be direc

connected to PCI bus and receives various compress

bitstreams and operating commands via the host interfac

A typical configuration is shown in Figure 1. Output vid

can be displayed on VGA monitor with video DAC or T

with TV encoder.

FEATURES

In VMI / VIP daughter-board applications, W9922PF

receives various compressed bitstreams via the graphic

accelerator which supports the VMI / VIP interface.

Figure 2 shows a typical configuration of VMI / VIP

daughter-board application.

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^Òdigital AC-3 2 or 5.1 channel encoded

up to 48 Khz sampling rate. As to outputs, it can be

Dolby^Òdigital AC-3 2 channel stereo or Pro-Logic

decoded stream. Software audio decoder supports

Multi-Audio , Muti-Language and high quality Dolby

Certification.
