PROBLEM TO BE SOLVED: To simply realize arbitration and synchronization of disk access by each server that is required to share in common a storage device by pluralities of video servers. SOLUTION: In this storage shared distributed video server system, a synchronization controller 13 repeats output of control signals S1 -Sn in a prescribed order at a predetermined prescribed time interval to each of servers 11-1 to 11-n to individually permit access of the servers to common share disk devices 12-1 to 12-m . Upon the receipt of a video data distribution request from a client, the server 11-i (denoting any of the servers 1-n) accesses a disk device storing video data on request among the common share disk devices 12-1 to 12-m for only a prescribed time period in response to the synchronizing signal Si received by itself. |
