Distributed channel time allocation for video streaming over wireless networks

摘要

A system for transmitting video from a plurality of transmitters to a plurality of receivers over a shared wireless channel includes a plurality of transmitters each receiving a respective video stream to transmit over the shared wireless channel. Distortion-related information is associated with each of the respective video streams and each of the plurality of transmitters having access to the distortion-related information for the respective video stream while not having access to the distortion-related information for other the video streams. Each of the plurality of transmitters using the respective distortion-related information of the respective the video stream to determine how to modify the video stream for transmission based upon a channel time constraint.

1. A system for transmitting video from a plurality of transmitters to a plurality of receivers over a shared wireless channel comprising:
(a) said plurality of transmitters each receiving a respective video stream to transmit over said shared wireless channel; (b) distortion-related information associated with each of said respective video streams; (c) each of said plurality of transmitters having access to said distortion-related information for said respective video stream while not having access to said distortion-related information for other said video streams; (d) each of said plurality of transmitters separately using said respective distortion-related information of said respective said video stream to determine how to modify a proportion of the available said shared wireless channel time for transmission based upon a channel time constraint and upon a cost function that includes a scaling factor, wherein the scaling factor continuously decreases over time.
