(registration process)
First, registration processing for registering a tablet PC 30 purchased by a user at a store as a remote controller of the set-top box 10 at home will be described with reference to a flowchart of FIG. As a premise, it is assumed that this user is a member of a store and the user information is already registered in the user management DB 241. It is assumed that information (MAC address, product code, firmware version, etc.) related to the home set-top box is set in the registered user information.

  The user purchases the tablet PC 30 at the store and informs the store clerk that he / she wants to use the tablet PC 30 as a remote control for the set-top box 10 at home together with his / her customer number. The store clerk connects the tablet PC 30 purchased by the user to the management server 20 in a wired or wireless manner. Then, the store clerk operates the operation unit 22 of the management server 20 and clicks a predetermined icon or the like displayed on the display unit 23. In response to this operation, the control unit 25 of the management server 20 displays a remote control setting menu screen on the display unit 23 and transmits an application program for causing the tablet PC 30 to function as a remote control to the connected tablet PC 30. As a result, the remote control function is installed in the tablet PC 30 (step S101). If the remote control function is already installed in the tablet PC 30, this process need not be performed. Alternatively, only the application program may be transmitted, and when the tablet remote controller is activated later, the application program may be executed to install the remote control function.

  Subsequently, the store clerk operates the operation unit 22 of the management server 20 to input the user's customer number in a predetermined column of the displayed menu screen, and registers the tablet PC 30 connected to the remote controller of the set top box 10. Instruct to do. In response to this instruction operation, the control unit 25 searches the user management DB 241 using the input customer number as a key, and acquires the user information of the user (step S102). And the control part 25 registers the MAC address of the tablet PC 30 currently connected to the acquired user information (step S103). This completes the registration process.

  With this registration process, when the user purchases the tablet PC 30, a remote control function is installed at the store, and identification information (MAC address) is associated between the set-top box 10 at the user's home and the tablet PC 30. Is called.

(Remote control processing)
After that, the tablet PC 30 thus registered for setting is used at the user's home. A process (remote control process) when the tablet PC 30 is used as a remote control of the user's home television or the set top box 10 will be described with reference to the flowchart of FIG.

  The user operates the input operation unit 32 of the tablet PC 30 to turn on the remote control function of the tablet PC 30. In response to this operation, the control unit 34 causes the input operation unit 32 to display a remote control screen as shown in FIG. 8 in which various buttons for remote control are displayed in a touchable manner (step S201). The user touches a button such as a channel button arranged on the remote control screen. In response to this touch operation, the control unit 34 transmits the instruction information (instruction command) corresponding to the touched button from the wireless communication unit 31 to the set top box 10 together with the confident MAC address (step S202).

  When receiving the instruction command from the wireless communication unit 15 (step S203), the control unit 16 of the set-top box 10 determines whether or not the MAC address of the tablet PC 30 received together with the instruction command is stored in the storage unit 14. Determination is made (step S204).

  If it is determined that it is stored (step S204; Yes), the control unit 16 executes a process based on the instruction command received from the tablet PC 30 (step S213), and the process ends.

  When determining that it is not stored (step S204; No), the control unit 16 sends an authentication request including the MAC address of the tablet PC 30 and the MAC address of the set top box 10 included in the instruction command via the Internet. To the management server 20 (step S205).

  When receiving the authentication request from the set top box 10 (step S206), the control unit 25 of the management server 20 refers to the user management DB 241 and the MAC address of the set top box 10 included in the authentication request and the MAC of the tablet PC 30. It is determined whether there is user information in which a pair with an address is stored (step S207).

  When it is determined that there is no user information storing such a set of MAC addresses (step S207; No), the set-top box 10 is illegally operated from the tablet PC 30 that is not permitted (registered) as a remote controller. There are cases. Therefore, the control unit 25 returns an authentication failure notification to the set top box 10 via the Internet (step S208). When the authentication failure notification is received (step S209), the control unit 16 of the set-top box 10 ends the process as an error, and the instruction command transmitted from the tablet PC 30 is not executed.

  When it is determined that there is user information in which such a set of MAC addresses is stored (step S207; Yes), the tablet PC 30 that is permitted as a remote controller (that is, a tablet registered as a remote controller by registration processing at a store) The set top box 10 is operated from the PC 30). Therefore, the control unit 25 transmits (replies) an authentication success notification to the set top box 10 via the Internet (step S210).

  When the authentication success notification is received (step S211), the control unit 16 of the set-top box 10 stores the received MAC address of the tablet PC 30 in the storage unit 14 for subsequent authentication (step S212). With this processing, subsequent instruction commands received from the tablet PC 30 are determined as Yes in the processing of step S204, and the tablet PC 30 can be authenticated without accessing the management server 20.

  Subsequently, the control unit 16 executes processing based on the instruction command received from the tablet PC 30 (step S213). For example, if the instruction command is a command indicating channel switching, the control unit 16 performs a process of switching the display channel by controlling the television connected via the external IF 12. The process ends here.

  As described above, in the first embodiment of the present invention, since the necessary settings and the like are already performed at the purchase store, when the user uses the tablet PC 30 as a remote controller at home, particularly complicated setting work or the like is performed. Without using it, it can be used without changing to a normal remote control. At this time, whether or not the tablet PC 30 has been previously authenticated (registered) using the identification information (MAC address) of the tablet PC 30 by the processing on the set top box 10 and the management server 20 side. Is determined, and only the authenticated tablet PC 30 accepts processing as a remote controller. Accordingly, it is possible to prevent the television and the set top box from being illegally remotely operated from an unauthenticated tablet PC 30 or PC. Therefore, the tablet PC 30 can be used as a remote controller safely and easily.
