Abstract
A home server is a home storage system that records viewer's favorite programs automatically for subsequent viewing at any time. We propose an HSMS(Hierarchical Storage Management System) as the architecture to make the home server interactive and give it a library function. The prototype home server can play back a recorded HDTV program(MPEG-2 MP@HL) while recording another HDTV program on a single hard disk. The HSMS also enables it to record five hours of HDTV programs and play them back without having to wait.
