Lossless VBR video broadcasting considering user bandwidth limit
Shufang Wu, Tsunehiko Kameda · 2005
The paper proposes a new video-on-demand (VOD) broadcasting scheme for variable bit rate (VBR) encoded videos; it is called forward segmentation using equal bandwidth (FSEB). For all practical purposes, FSEB solves the elusive problem of minimizing the server bandwidth for delivering VBR videos with no loss, given an upper bound on the wait time, a uniform upper bound on the channel bandwidths, and the number of channels that a user can access simultaneously. FSEB takes a video as a frame sequence, divides the video into segments, and broadcasts each segment periodically on a separate logical channel. Experimental results with real videos reveal that FSEB requires less server bandwidth and user bandwidth than the only other lossless scheme for VBR videos currently known, which also can limit the number of channels that a user can access simultaneously.
