SYSTEM AND METHOD FOR DISTRIBUTING DIGITAL DATA ON DEMAND

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive system which can be adjusted to various conditions and which can be extended in accordance with the increase of demands by processing a command from a client, scheduling the reproduction of a video stream, managing a video file structure and controlling the flow of video data to distribution modules by respective central control modules. SOLUTION: A video server 105 is provided with the central control modules 110, the distribution modules 120 and a storage module 130. The respective central control modules 110 receive and process a video control command from the client 101. The central control modules 110 execute a multi-task processing by using a program code stored in DRAM 232 connected to CPU 112. The program code contains a multi-processing thread executed by CPU 112 and the multi-processing thread reproduces the multiple video streams by the demand by the client 101 and execute the various control commands.
