Abstract: A video server is interconnected through a LAN and the like to other video servers, allowing data transmission/reception among the video servers. Users are connected through a network to a server managing portion. The server managing portion receives access from the users to make an instruction to the video server. An access amount managing portion manages an access amount of the video server to determine whether to perform expanding processing of a VOD service. When the expanding processing is to be performed, a data copy processing portion checks an amount in the other video server, and copies data to the other video servers as required. Then, the server managing portion distributes access processing. It is thus possible to improve expandability of the VOD service as to data and the like to which a large amount of access is made in the video server, allowing the availability of a comfortable VOD service system to the users.
