Effective utilization of disk bandwidth for supporting interactive video-on-demand

This paper proposes a novel data retrieval scheme that achieves effective utilization of disk bandwidth for designing fully interactive video-on-demand systems. The main distinctions of the proposed data retrieval scheme are (1) it requires no extra disk bandwidth to support interactive features such as fast forward search and fast backward search; and (2) it is based on a data placement scheme that can effectively utilize disk bandwidth during normal-speed playback.
