  • Patent number: 8719437
    Abstract: A method for enabling streaming to a media player without native streaming support is disclosed. Step (A) of the method may author a media file based on a content signal. The media file may have an indexed format compatible with the media player. The content signal may (i) be received from a remote server through a network, (ii) use a transfer protocol and format at least one of which is incompatible with the media player and (iii) convey both video data and audio data representative of a scene. Step (B) may generate a local signal carrying the media file. The local signal generally has a transfer protocol compatible with the media player. Step (C) may transfer the local signal to the media player while the content signal is being received. The media player generally recreates the video data as a visual depiction on a display based on the local signal.

  • Patent number: 7142566
    Abstract: The present invention relates to systems and methods for processing and transmitting data that preserves the timing relationship of the data being transmitted and/or processed. In one embodiment, the present invention uses a timestamp. The timestamp stores the timing relationship of data in the bitstream as it appeared before any processing that may alter the timing relationship of the data. The data may then be processed. By storing the original timing relationship of data, before any processing that alters the timing relationship of data, the present invention allows for the recreation of the original timing relationship between data. Thus, any jitter introduced by processing the data may be removed or substantially reduced.

  • Patent number: 7003062
    Abstract: The present invention discloses a method and system for synchronizing processing modules. More specifically the present invention utilizes a master clock signal and associated synchronization information to coordinate the function dictated by packets within a synchronization stream. The master clock has multiple sources. Each module in the system is connected to each clock source to ensure that if one source fails, the module will not fail. The clock signal to each module is further passed through a locked oscillator, which will continue to maintain the clock signal should the master clock signal fail. Each module contains a sync decoder to decode the SYNC packets in the synchronization stream, into system time events. The system time events are then passed to a plurality of event receivers. Each event receiver contains at least one flywheeling counter to ensure that each event receiver remains in synchronization with the system time events being passed by the sync decoder.
