  • Patent number: 7787580
    Abstract: Method and systems for aligning a clock at a second device based on a reference clock at a first device and reducing clock rate jitter between asynchronous devices in a network are disclosed. A transmission latency may be determined between the first device and the second device. A data packed may be received containing information pertaining to the reference clock at the second device. The phase of the clock may then be adjusted at the second device based on the information contained in the packet and the transmission latency.

  • Patent number: 7523362
    Abstract: A data transmission and distribution system includes a series of payloads, where each of the payloads is formed from bits of audio or video information, and where different levels of protection are applied to different sets of bits in each payload. The system divides the bits associated with each payload into high priority bits and low priority bits and forms a group of check bits for each payload by applying an error correction algorithm to the high priority bits in the payload. The system also forms each payload from a first set of high priority bits, check bits and low priority bits and a redundant set of high priority bits and check bits and transmits the payloads formed from the first set of the high priority bits, the check bits, the low priority bits and the redundant set of high priority bits and check bits.

  • Publication number: 20080310461
    Abstract: A system for transmitting and distributing audio or video information. The system includes a multi-channel input module and multiple receivers arranged along at least one chain of high speed serial data links where each receiver can tap into a common set of digital channels generated by a transmitter. Each receiver can create its own user adjustable mix based on one or more signals from the common set of digital channels.

  • Patent number: 7301966
    Abstract: A data transmission and distribution system that includes a transmitter and a receiver. The transmitter transmits a count value associated with a data clock of the transmitter to the receiver over an asynchronous link as part of an information payload that also includes audio or video information. The data clock is synchronously recreated at the receiver using only a system clock associated with the receiver and the transmitted count value.

  • Publication number: 20030165163
    Abstract: A system for transmitting and distributing audio or video information. The system includes a plurality of input modules arranged in series along at least one chain of high speed serial data links that end with a master module. Each input module receives mixing instructions addressed to that module and then passes a signal mixed in accordance with the instructions to the next input module in the chain where no human perceptible delay is introduced into the mixed signal as it moves through the chain.

  • Publication number: 20030161324
    Abstract: A data transmission and distribution system that includes a series of payloads. Each of the payloads is formed from samples of audio or video information. The system interleaves the audio or video samples in each payload where no two consecutive samples are lost upon a loss of an entire frame of the interleaved samples.
