    Abstract: Presented herein are method(s) and apparatus for demultiplexing, merging, and duplicating packetized elementary stream/program stream/elementary stream data. In one embodiment, there is presented a method for processing data. The method comprises receiving a bitstream wherein said bitstream comprises a plurality of streams; mapping the plurality of streams to a plurality of identifiers; packetizing the plurality of streams, thereby resulting in a plurality of packets, and wherein each packet further comprises: a portion of only one of the plurality of streams; and a particular one of the identifiers, wherein the particular one of the identifiers is mapped to the only one of the plurality of streams.

    Abstract: Systems and methods for processing media information are disclosed and may include tracking a number of times that at least one stored identifier that identifies program content for a particular data channel that is received via one of a plurality of multiplexed transport data streams is modified. At least a portion of the received program content for the particular data channel may be discarded based on the tracking. The at least one stored identifier that identifies the program content for the particular data channel may include a packet identifier (PID) and a processor identifier associated with the PID that identifies at least one of a plurality of processors that parses at least a portion of the program content for the particular data channel that is received via one of the plurality of multiplexed transport data streams.

    Abstract: Certain aspects of changing message filter coefficients dynamically in a packetized network system may comprise selecting a filter for filtering data in a first portion of an incoming data stream. At initiation of a new modification process, a determination may be made as to whether the selected filter is in use and if so, data read by the selected filter may be invalidated or otherwise not utilized for its intended purpose. A selected filter may be marked as being in use prior to being updated, indicating that there is no match for the selected filter. Filter coefficients for the selected filter may be updated while the selected filter is marked as being in use. Upon completion of updating the filter, the selected filter may be marked as not being in use.

    Abstract: The present invention is directed to a system and method 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.
