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 at any time. We have developed a hierarchical storage management system (HSMS) as the architecture for developing a high-speed home server with very large capacity. This paper first describes the required specifications and memory construction of the home server and then proposes a model of the new HSMS. Also described are its element technologies and an experimental home server system, and the results of experiments conducted to test its performance.
