摘要： Presented are a system and method for distributing video over a network. The system includes a source that outputs video with a first frame rate, a transmitter, a receiver, and a sink. The transmitter receives video from the source and processes the video by encoding the video with frame boundary information, packetizing, and transmitting the video. The receiver includes a frame buffer, a timing generator, and a PLL. The receiver receives and processes the video by retrieving the frame boundary information, decoding the video into sub-frames, and writing the sub-frames to the buffer. All the processing occurs on sub-frame portions of the video in sub-frame time intervals. The receiver transmits video with a second frame rate to the sink. The timing generator generates output timing and uses the PLL to synchronize the output timing with the frame boundary information and synchronizes the first and second frame rates.

摘要： A master transmitter distributes a plurality of audio channels to one or more expansion receivers as a multiplexed audio stream. Control information is also transmitted between the master transmitter and the expansion receivers. Both the control information and the multiplexed audio stream are transmitted on the same cable allowing for reduced clutter and cheaper material and installation costs.
