摘要： In a video storage and delivery apparatus and corresponding system, video data items are simultaneously supplied to a plurality of users while guaranteeing the time axis and the picture quality of the video data. The apparatus includes a frame address table which indicates a storage location in the apparatus of each frame of video data to start a special reproduction or a reproduction at a desired frame and a control unit controlling a switch bus connecting a plurality of video storage and delivery apparatuses to a plurality of channels so as to conduct data transfers via the switch bus between the apparatuses and between video reproduction devices of the users. From an optical disk data storage storing video data, a plurality of video data items are read in a timesharing fashion to be temporarily stored in a magnetic disk device or a semiconductor memory, thereby delivering the video data items therefrom to the users.

摘要： A WEB server includes a control unit for HTTP server, a table of addresses of VOD servers, and a table of identifiers of video data. The control unit accesses these tables, in response to a request from a user of a terminal device for a display of video data, to retrieve therefrom an address of a video server and an identifier of a title of video data related to information on a WEB page accessed by the user, then transfers the address and the identifier to the terminal device. This enables the user of a video-on-demand system to easily obtain video data associated with information on the WEB server.

摘要： In a network cache and a cache control method involving the transfer of a large volume of data as the time of reproduction of multimedia data including video data, a stabilized data transfer is made by eliminating the waste of cached data or a useless cache processing which may be caused by the interruption of a user's operation. When a data transfer request from a user terminal connected to a local network is made to a server existing on the internet, a user request processing program starts a cache program. The cache program performs a cache processing independently of the data delivery to the requesting user terminal by the user request processing program so that even if the user's request is interrupted, the storage of transferred data into a cache file is performed without ceasing. Also, a required bit rate for data made an object of transfer is analyzed for comparison with a network throughput between the server and the network cache. When the network throughput is larger, the caching of transferred data is not performed so that the discard of data having been cached is not caused. Thereby, it is possible to prevent the cache hit rate from being lowered.
