摘要： A device registration system for registering a terminal device for obtaining and using contents in a server that stores contents. The server stores a contents list indicating contents stored and a registration list for registering specific information to the terminal device. The server receives the specific information and transmits the contents list to the terminal device. The terminal device receives a selection of a content from the contents list according to input by a user and requests the server to transmit the selected content. When the specific information to the terminal device of the request source is not registered in the registration list, the server performs a registration process and transmits the requested content to the terminal device.

摘要： A system including a server holding content and a terminal using the content, whereby the terminal is registered in the server if a communication time between the terminal and the server is less than or equal to a reference value. A measuring unit of the server measures a communication time from transmitting measuring information to the terminal until receiving response information from the terminal, and repeats the transmission, the reception, and the measurement until the measured communication time is less than or equal to the reference value. An elapsed-time measuring unit measures an elapsed time from when the measuring unit first begins measuring the communication time, and a transmission unit transmits, to the terminal, status notification information showing a processing status depending on the elapsed time. A response unit of the terminal receives measuring information from the server and transmits response information to the server when the measuring information is received.
