Abstract: A mobile terminal includes: a first manner of wireless communicator for conducting wireless communication with a client terminal; a second communicator for conducting wireless communication with a network (NW1); storage for storing data; and communication control for causing data to be transmitted between communicators. The communication control causing data received via the second communicator to be stored when a client terminal is in a state in which the client terminal does not receive data, and causes the stored data to be transmitted by the first communicator when the client terminal is in a state in which the client terminal receives data. Further, the communication control causes the data received via the first communicator to be stored when wireless communication with the network is not possible, and causes the stored data to be transmitted by the second communicator when wireless communication with the network is possible.

Abstract: An HGW mobile device 20 can perform data communication on the basis of a plurality of wireless communication methods with different theoretical maximum transmission speeds, i.e., on the basis of a mobile wireless communication method and a wireless LAN communication method. Since the HGW mobile device 20 is provided with a mobile wireless communication unit 210 and a wireless LAN communication unit 250, it is able to relay data transmission between an external network 10 and a client terminal 30. A transmission speed initializing unit 230 sets a value according to a theoretical maximum transmission speed of the wireless communication method with the slower theoretical maximum transmission speed, i.e., the theoretical maximum transmission speed of the mobile wireless communication method, as an initial transmission speed for the wireless LAN communication unit 250 to first start wireless LAN communication with the client terminal 30 on the basis of the wireless LAN communication method.

Abstract: An object of the present invention is to provide a communication terminal and a communication method that can reduce power consumption while securing a communication state by a first communication means or a second communication means. A mobile device includes a radio communication part that communicates and connects with a mobile communication network and a WLAN communication part that communicates and connects with a WLAN. In the mobile device, a communication state monitoring part judges whether or not a radio communication using the radio communication part can be performed based on a preset reference value. When the communication state monitoring part judges that the communication using the radio communication part can be performed, a control part causes the WLAN communication part to transit to a sleep state.

Abstract: To appropriately perform a process for license issuance to a client terminal, in a license issuing system, when a client terminal fails to obtain a license from a server in spite of transmitting a license issuance request, the client terminal transmits a license issuance request including the same key information as in the initially transmitted license issuance request to the server. The server stores the key information contained in the initial license issuance request in the key information storage unit, confirms that the stored key information is the same as the key information contained in the second license issuance request, and issues a license again. The client terminal deletes the key information contained in the license issuance request after obtaining the license.

Abstract: A broadcast receiving terminal includes a conditional access system (CAS) module that acquires key information from a broadcast signal and a renderer that plays back video/audio data in the broadcast signal. The CAS module includes a history information storage unit that stores playback history information and a playback time calculation unit that calculates playback remaining time information related to the video/audio data and sends a scrambling key and the playback remaining time information to the renderer. The renderer includes a descrambling unit and a decoding unit that decrypts the video/audio with the scrambling key to play them back and send history information related to the playback to the CAS module and a preview control unit that performs control to decrypt the video/audio data only for the time indicated by the playback remaining time information. The terminal achieves playback control in accordance with an actual playback time.
