Providing VCR Functionality in a Constant Quality Video-On Demand Transportation Service
The use of bandwidth smoothing techniques for the delivery of prerecorded compressed video has been shown to be an effective technique in reducing the network bandwidth requirements needed to play back video. Any fixed allocation scheme can affect the ability to allow for VCR functions. In this paper, we examine the impacts that bandwidth smoothing techniques have on the delivery of stored video. We introduce the notion of VCR-window, which allows users to have full VCR functionality in a limited window while not requiring increases in the bandwidth reservations. In addition, we introduce a resource reservation scheme that can be used with the VCR-window for the delivery of stored video. To test the applicability of the VCR-window in video-on-demand systems, we have digitized 15 full-length movies for experimental data. Our results indicate that we can provide time-limited VCR functionality while retaining a fairly high network utilization. Key words: Video-on-demand, VCR functionalit...
