    摘要: A system and method is provided for generating and using multiple synchronized local program timestamps in a media processing system. The system includes an input processor, one or more local timestamp insertion modules, one or more parsers, and an input buffer. Each local program timestamp module includes a clock reference recovery module, a local program clock synchronized to the system time clock of a program source, and a timestamp generator. The system also includes one or more processing modules such as record modules, transmission modules, and display modules. When a data packet is received by the media processing system, the local timestamp insertion module appends a timestamp to the data packet. The timestamp is based on the synchronized local program clock for the program associated with the data packet. The processing modules utilize the synchronized local timestamps and their associated local program clock in a variety of applications.

    摘要: The present invention is directed to a system for demultiplexing video signals that have been combined using a time division multiplexing approach. The system includes synchronizers, parsers, demultiplexers, and an input buffer. Each demultiplexer within the system includes a header detect module, a slot map module, a frame sync module and a packet accept module. The method includes the steps of receiving an input stream that contains data packets for more than one program channel that have been combined in which packet identification (PID) information is used and a time division multiplexing scheme, such as transport stream multiplexing format (TSMF) is used. The PID and slot location for each packet is analyzed. Based on the PID and slot location a packet is either accepted or rejected.
