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.","PeriodicalId":393861,"journal":{"name":"ISCE '97.

We designed it to be compact and efficient by utilizing the rule of the DVD recording code. By experiment, we confirmed that the Viterbi decoder reproduced digital data more precisely than a conventional bit-by-bit decoder. Thereby it improves the reliability of the DVD players. It was integrated into a data processing LSI which restores digital data streams recorded on the DVD. By employing this LSI, we have developed DVD video players, DVD-ROM drives, DVD-recordable drives, and DVD car navigation systems. We applied the Viterbi decoding to home-use optical disc players for the first time.","PeriodicalId":393861,"journal":{"name":"ISCE '97.

For occluded area, occluded points are coded independently and non-occluded points are fed into the dynamic programming to find disparity vectors. Since the proposed method provides a more realistic disparity vector field and increased coding efficiency, improved picture quality can be obtained.","PeriodicalId":393861,"journal":{"name":"ISCE '97.

The algorithm with a moderate window size has a shorter acquisition time than the immediate verification algorithm has-especially in low Ec/No. This results from the fact that the window-based algorithm, which verifies only one code phase that has maximum correlation output, consumes an additional penalty time in each window even in the condition of frequent false alarms. As the mean acquisition time varies with the window size, we may have fast code acquisition with the proper window size according to the Ec/No.","PeriodicalId":393861,"journal":{"name":"ISCE '97.

It is implemented by the high technology of multimedia, information communication and software. This system is a low cost application system for the general home PC user. With the network environment of this system it is possible to construct a superhighway by connecting various network with the home network backbone POF (plastic optical fiber in the home) which is an IEEE 1394-1995 standard specification. We connected the Internet, intranet and various household electrical appliance (video, audio, PC, TV, phone, fax) with the home network backbone. Then we can use convenientiy/efficiently the multimedia home PC for the integrated home information service by the DooRae framework for an integrated information service. The Doorae distance home study system has many functions which are application (audio/video/text data, teaching materials, DB) sharing, white board to support interaction, a video window for participators, audio for dialogue, user's interface with icon and a environment configuration for collaborative multimedia distance education within the home.
