If it is determined that it is not connected (NO in step S132), the control unit advances the process to be executed to the process in step S141 of FIG.

  On the other hand, when it is determined that it is connected to the home network (when YES is determined in step S132), in step S133, the control unit multicasts the authentication token created in step S128 toward the home network.

  In the present embodiment, UPnP (Universal Plug and Play) is used as a protocol for transmitting an authentication token. By using UPnP, it becomes possible to send arbitrary information to devices on the home network. Furthermore, since UPnP packets are not transferred to the outside of the home network beyond the router, the connection destination can be limited to the devices on the home network and illegally connected from the devices outside the home network. This can be prevented. In addition, it is possible to prevent an unintended operation as a result of unauthorized connection.

  In step S134, the control unit waits for reception of a connection confirmation response transmitted from another terminal device as a response to the authentication token for a predetermined time. In step S135, the control unit determines whether or not a connection confirmation response has been received from another terminal device. If it is determined that it has not been received (NO in step S135), the control unit advances the process to be executed to the process in step S141 of FIG.

  On the other hand, if it is determined that the connection confirmation response has been received (YES in step S135), in step S136, the control unit determines the service logged in at the terminal device and the service included in the connection confirmation response. Whether the service indicated by the information for identification is the same, that is, whether the logged-in service is the same between the terminal device connected to the home network and the other terminal device. to decide.

  The terminal device that has received the authentication token determines whether or not the logged-in service is the same. Based on the determination result, the connection confirmation response indicates whether or not the service is the same. In step S136, information indicating whether or not the services included in the connection confirmation response are the same is included. Based on this, it may be determined whether the logged-in services are the same.

  When it is determined that the logged-in services are not the same (when NO is determined in step S136), the control unit advances the process to be performed to the process of step S141.

  On the other hand, if it is determined that the services are the same (YES in step S136), in step S126, the control unit selects a terminal device indicated by information for identifying the terminal device included in the connection confirmation response. Then, register it as a connection partner in the storage unit. Then, the screen shown in FIG. 12 is displayed.

  Next, in step S138, as in step S127, the control unit executes a function predetermined according to the service and the other party. After step S138, the control unit advances the process to be performed to the process of step S141.

  As described above, during connection to the home network, unless the connection partner is registered, the authentication token is periodically transmitted by multicast.

  In addition, you may make it transmit to the service provision server 200 directly not via the terminal device which is performing the moving image reception reproduction | regeneration function.

  When it is determined that various operations have not been performed (when NO is determined in step S141), and after step S142, in step S143, the control unit is the same because the two terminal devices are connected to the home network. It is determined whether or not any information has been received from another terminal device or the service providing server 200 while logging in the service.

  When it is determined that some information has been received (when YES is determined in step S143), in step S144, the control unit executes processing according to the received information.

  For example, when an operation content of the remote control is received from another terminal device that is executing the remote control function, a process of relaying the operation content and transmitting it to the service providing server 200 is executed.

  In addition, in a terminal device that is executing a video reception / playback function, when a video streamed from the service providing server 200 is received, a playback process is performed while receiving the video.

  When it is determined that any information is not received (when NO is determined in step S143), and after step S144, in step S151, the control unit disconnects the terminal device of the connection partner from the home network. Alternatively, it is determined whether or not the terminal device is disconnected by logging out from the service of the service providing server 200.

  When it is determined that the terminal device of the connection partner is disconnected (when YES is determined in step S151), in step S152, in addition to the function being executed, the control unit is being executed on the disconnected terminal device Perform the function. That is, the two terminal devices shift to a state where they receive a service independently without cooperation.
