| W9922PF MPEG-2 VIDEO DECODER 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. 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. 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.
