Abstract: An information terminal capable of communicating with a broadcast receiving device that receives TV broadcast includes a communicator, a storage unit for storing an application program that prescribes communication processing with the broadcast receiving device, and a controller. The controller performs mutual authentication with the broadcast receiving device to transmit first authentication information to the broadcast receiving device. Furthermore, the controller verifies validity of the application program stored in the storage unit. When the verified application program is valid, the controller performs control to transmit second authentication information verifiable by using the first authentication information in communication with the broadcast receiving device according to the application program.

Abstract: In one aspect, when a user directs a remote controller (13) toward a television set (11), causing the remote controller (13) and the television set (11) to enter the wireless communication region of each other, the remote controller (13) and the television set (11) establish a wireless link to each other. When the user directs the remote controller (13) toward an air conditioner (12), causing the remote controller (13) and the air conditioner (12) to enter the wireless communication region of each other, the remote controller (13) and the air conditioner (12) establish a wireless link to each other. The remote controller (13) and the television set (11) are out of the wireless communication region of each other at this point, and the wireless link between the two is thus disconnected.

Abstract: An information providing system includes a supplementary information server that provides supplementary information related to video to be broadcasted, a video receiving device that receives via broadcast the video and first specifying information for specifying the supplementary information related to the video, a terminal device that receives the first specifying information from the video receiving device and second specifying information for specifying the supplementary information from another apparatus different from the video receiving device, and a management unit that discriminates between the first specifying information and the second specifying information to manage frequency with which the terminal device receives the first specifying information.

Abstract: An information provision system provides a program-related information in parallel with broadcast of a television program. The system includes: a program-related information server; a television receiver; and a terminal apparatus. The terminal apparatus includes: a display unit; a program-related information display controller for acquiring the program-related information, and for displaying the acquired program-related information in a first display region on the display unit; and a net information display controller for acquiring net information from a net information server, and for displaying the acquired net information in a second display region on the display unit. The net information display controller displays the net information in the second display region after a lapse of a predetermined delay time.

Abstract: An information providing system includes a television receiver, a user terminal, and a connection state management server each connectable to a network. The user terminal can execute a program for connecting with the television receiver. The connection state management server obtains connection state information including an identifier of the television receiver and an identifier of the user terminal, through a network from one of the television receiver and the user terminal connected to each other. Further, the connection state management server scores a degree of relevance representing a level of relevance between the television receiver and the user terminal connected to each other, based on the obtained connection state information. Furthermore, the connection state management server provides the scored degree of relevance to a request source in response to a request from an outside.

Abstract: There is provided a stream transmitter for generating and transmitting a digest stream that is a single stream into which digests, each having a predetermined time length, cut out from the respective plurality of video contents stored in a contents storage are combined. This configuration allows a user to view the digest stream, which collects the digests of the respective contents, and select a desirable program by viewing each digest.
