Abstract-One way to broadcast a popular/hot video is to let multiple users share a few channels. The stress on the scarce channels can be alleviated without sacrificing viewer waiting time. One common approach is to partition the video into fixed-length segments, which are broadcast on several channels periodically. Two representative approaches are the Fast Broadcasting scheme and the PAGODA scheme, which can broadcast a video using channels by having new viewers wait no longer than 2( 2 ) and 2( 5 2 ) time, respectively, where is the length of the video. In this paper, we propose a new scheme, called Recursive Frequency Splitting (RFS), that significantly improves on existing schemes in terms of viewer waiting time. Some lower bounds on the viewers' waiting time are also developed. Index Terms-Broadband networks, broadcasting, cable TV, digital video broadcasting, scheduling, video-on-demand (VOD).
The Recursive Frequency-Splitting scheme ( REF ) improves some of the results of the new Pagoda scheme.
