Abstract: A processing unit detects whether externally input user personal information has been stored in a storage medium. A network interface transmits a transmission of available/unavailable request information identifying a broadcast station that broadcast received broadcast information, if the externally input user personal information has not been stored in the storage medium. The network interface receives available/unavailable information in a reply to the transmission. The available/unavailable information shows whether an external device offers a service providing related information about contents included in the received broadcast information. The network interface transmits the externally input user personal information to the external device to request a user registration in accordance with the available/unavailable information, if the processing unit detects that the externally input user personal information is not stored in the storage medium.

Abstract: A client terminal CT transmits an acquisition request for musical composition information. An associated information provision server KS continuously receives the acquisition request at a given time interval. The associated information provision server KS transmits timing specification information along with the musical composition information corresponding to the acquisition request to the client terminal CT. The timing specification information specifies timing for the client terminal CT to transmit the acquisition request next. The associated information provision server KS controls a polling interval for acquisition requests. In this manner, acquisition requests can be distributed to those transmitted at a given time interval and those received in accordance with the timing specification information. A simple method can be used to prevent acquisition requests from being concentrated on the associated information provision server KS.

The interface transmits a ticket to the external apparatus, in response to the reception of the ticket request, based on the result of the authentication based on the user ID data and the apparatus ID data.

Abstract: To further correctly obtain related information about contents being received from a server. A communication apparatus 1 successively transmits request information that requests related information about contents being received via a network 30, at specified intervals (S1), receives related information corresponding to that request information (S2), temporarily stores (S3), displays it (S4), and performs contents updating processing. Here, if a direction to store the related information about the contents is entered, the communication apparatus 1 requests again request information for related information about contents, separately from the contents updating processing (S10). Then, the communication apparatus 1 receives related information corresponding to that request information (S11), and stores it (S13). This enables the latest related information to be further correctly obtained out of related information concerning contents, and obtaining related information before updating is reduced.
