This paper presents a comprehensive procedure to design multimedia storage systems for on-demand playback. The design stresses effective utilization of disk bandwidth with minimal data buffer to minimize overall system costs. The design procedure is most distinctive in the following two aspects: 1. It bases on a tight upper bound of the lumped disk seek(More)
This paper proposes a design procedure that exploits storage devices with diierent cost/bandwidth and cost/capacity ratios to build a hierarchical storage system for video-on-demand with minimum cost. The storage system is assumed to have two levels of hierarchy. The level-1 storage devices feature a low cost/bandwidth ratio and a high cost/capacity ratio.(More)
