Television home server for integrated services-toward the realization of ISDB "anytime" services

In the age of digital multimedia, demand is bound to rise for a television home server for integrated services which automatically records favorite programs so that users can watch them anytime. We have developed a hierarchical storage management system (HSMS) as the architecture for the development of a high-speed home server with a very large capacity. This paper first describes the required specifications and memory constructions of the home server and then proposes a model of the new HSMS. Also described is its element technologies and an experimental home server system, and the results of the experiment we conducted to test its performance.
