The Video Decoder(VD) decodes video elementary stream of MPEG-2(ISO/ICE 13818-2)MP@HL. It supports the ATSC digital TV video standard, and can be used for the video part of the ATSC digital TV with the Transport Decoder and the VDP(Video Display Processor). Picture decoding timing can be controlled internally for A/V lip synchronization, and externally for Video Trick Mode by host microprocessor via I2C bus. The Video Decoder can extract video user data including caption from video elementary stream, and host microprocessor can read the video user data from the Video Decoder(VD) via I2C. It uses four 16x1M SDRAMs and can support up to 81 MHz memory clock speed.
