Abstract
A digital video network interface for transferring isochronous video data over an asynchronous local area network, including an isochronous interface for transmitting digital video data isochronously, a memory comprising first and second buffers for storing the isochronous video data, a network interface for transmitting video data from either the first or second buffers over the asynchronous local area network, and a memory buffer manager for controlling the output of the video data over the asynchronous local area network and for controlling the input/output of video data into/from the first or second buffers, wherein, when either the first or second buffers is filled with video data, the memory buffer manager shifts the input of data into an empty buffer and begins outputting video data to the asynchronous local area network from a filled buffer, upon receiving access to the local area network. Complementary ones of such video network interfaces may be provided on a network so as to permit one-way video streaming (to one or more receiving sites) or two-way video conferencing with network interfaces operating in full-duplex mode.
