摘要： A system and method for distributing high definition television (HDTV) and standard definition television (SDTV) signals via satellite is disclosed. At the transmission station an MPEG-2 video encoder compresses a video signal and a digital encoder encodes an audio signal. The compressed video and the encoded audio are coupled to PES packetizers, which generate video and audio packetized elementary data streams having PES headers and PES payloads. Within each PES header is a presentation time stamp (PTS), which is representative of the time at which the payload is to be displayed to the user. The packetized elementary data streams are multiplexed together by a transport multiplexer and repacketizer and broadcast to receiver stations, via satellite. The receiver stations receive the PES information and obtain the PTS. A receiver station multiplies the PTS by 300 and compares its local clock reference to that time. When the local clock reference and the PTS are identical, the PES audio and video information is displayed to the user according to the local clock reference.
