摘要： Essential data elements, particularly entitlement control messages (ECMs), are inserted in a manner that reduces the overhead bit rate without effecting overall tuning time at the customer receiver or security in satellite, cable or other programming networks. ECMs are inserted into the transport stream by detecting random access points (RAPS) in the encoded programming and inserting the ECM packets in a window just ahead of the RAP.

摘要： A system and method for adding auxiliary data DA to an output data stream from a statistical multiplexer is disclosed. An auxiliary multiplexer accepts a statistically multiplexed data stream, and substitutes auxiliary data packets for null data packets. The auxiliary multiplexer controls the number of null packets in the statistically multiplexed data stream by controlling the target bandwidth BT of the statistical multiplexer, or by modifying the statistical multiplexer equation to make the auxiliary data stream a participant in the negotiation process of allocating throughput among the data sources.

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.
