3 January 1996 Periodic broadcasting approach to video-on-demand service
Author Affiliations +
The goal of Video-On-Demand (VOD) service is to allow users to access arbitrary video sequences at arbitrary time across wide-area networks. Because of the large amount of data volume associated with real-time video, the communications and I/O bandwidth requirements pose an extremely difficult challenge to computer systems designers. This paper focuses specifically on the I/O subsystem design for large-scale video servers. We describe a periodic broadcasting approach and its associated data layout algorithms to cost-effectively address the I/O bandwidth problems associated with large-scale VOD servers. The paper also presents techniques to support a limited form of VCR-like trick plays such as fast forward and reverse under the proposed framework.
