PROBLEM TO BE SOLVED: To solve a problem that since an operation of a user with high priority in time is executed when a plurality of users simultaneously operate one device, another user can not utilize it or the device is freely used by a user having preference by selecting a priority selection key. SOLUTION: When the user requests a right of use when control by only one user is possible, a device use request from the user is transmitted to a first AV transmission management terminal (receiver: B), the first AC transmission management terminal (receiver: B) transmits user information and a use right request to which information including an ID of the device of which the use is desired, etc. is attached to an AV transmission management terminal on the side of a controlled device. The AV transmission management terminal collates (retrieves) a transmitter side device DB (queue) and registers the user information of the user who performs the request. Next, a result of the use right request is transmitted to the first AV transmission management terminal (receiver: B). As a result, acquisition of a control right, acquisition of an audience right and waiting for acquisition of use right (both control and viewing (use) are impossible at present) are included. Then, the obtained result is presented. COPYRIGHT: (C)2005,JPO&NCIPI
