  • Patent number: 6356212
    Abstract: A device and method for utilizing a single clock signal to generate a digital data stream signal for transmission in a compressed domain transmission system. The device includes a plurality of packetized elementary stream encoders electronically coupled to a transport stream encoder electronically coupled to an output interface adapted to generate the digital data stream signal.
    Type: Grant

  • Patent number: 6330286
    Abstract: In a compressed domain digital communications system, a method for reducing a variable latency associated with a buffer and at least partially resulting from at least one splice between a FROM bitstream and a TO bitstream each including data corresponding to a plurality of frames, the method including: selectively deleting data corresponding to a select at least one of the frames from the buffer based upon the variable latency so as to reduce the variable latency when an amount of data corresponding to a number of frames present in the buffer is greater than a given number of frames; and, regulating a flow of data in the system to prevent an underflow condition in the system by effecting a repeat last frame command and prevent an overflow condition in the system by slowing a rate of transmission for the data associated with at least one of the frames in the TO bitstream.

  • Patent number: 6101195
    Abstract: An apparatus and method for receiving an information stream comprising a plurality of timing portions and associated payload portions, decoding each timing portion, determining a duration parameter of a payload portion associated with the decoded timing portion, and recoding the timing portion using the duration parameter and a local reference time parameter.

  • Patent number: 6061399
    Abstract: A timing synchronization method and apparatus for processing a compressed information stream comprising a plurality of information segments representative of a sequence of information frames. Information segments representative of information frames are deleted in response to an indicium of buffer overutilization.
