A BROADCASTING PROTOCOL FOR COMPRESSED VIDEO

Video broadcasting protocols can improve the efficiency of video on demand services by reducing the bandwidth required to distribute the videos that are simultaneously watched by many viewers While many broadcasting protocols have been proposed, none of them takes into account the fact that the server will broadcast compressed videos whose bandwidth requirements depend on the rate of change of the displayed images. We present here a new broadcasting protocol specifically tailored for the task of broadcasting compressed video. Our protocol continuously broadcasts the first segment of each video in real time. It then broadcasts the remaining segments of the video at frequencies ensuring that each segment can be completely downloaded by the time the customer has finished watching the previous segment. Hence these segments do not require excess bandwidth.
