Abstract: Setting and operation of a TV, a mobile terminal, and the like are extremely complex to an ordinary user. Even when part of the setting and operation is automatically done, still a change needs to be performed so as to meet the needs of the user according to a use status. In view of this, a RFID tag (8007) of a mobile AV terminal (8006) is brought into proximity of a RFID tag (8007) of a TV 1 to exchange the use status between the terminals, and then a command is generated on the basis of the use status and issued to a server apparatus or the like. Thus, by a simple touching operation (moving the terminal close to the other terminal), it is possible to communicate information for authentication and timing synchronization and thereby meet the needs of the user, with there being no need for the user to perform complex setting and operation.
