(Operation of this embodiment)
Next, the operation in the present embodiment will be described. Here, an operation for displaying a file in the storage device 4 on the display device 3 will be described.

FIG. 5 is a sequence diagram for the operation of the present embodiment.
When the user performs a predetermined operation on the remote controller R, the display device 3 requests the first gateway device G1 to transmit a selection menu (S1).

  If such a request is transmitted, the first gateway device G1 requests the control server 1 to transmit a two-dimensional code (S3).

  In the control server 1, the two-dimensional code generation unit 11 is information for generating a two-dimensional code and information for authenticating whether the character string transmitted from the two-dimensional code reading device 5 is correct. Authentication information (a character string made up of a random character string generated by a random number and information related to the first gateway device G1 (for example, identification information)) is hashed with a predetermined hash function H to obtain a character string, and the control server 1 A two-dimensional code (QR code) corresponding to a URL (Universal Resource Locator) which is location information added with the character string as an argument (referred to as an access key) is generated (S5). The format of the two-dimensional code is, for example, JPG.

  The two-dimensional code generation unit 11 stores the authentication information in the authentication information storage unit 12 in association with the expiration timing of the expiration date (S7).

  The control server 1 transmits the two-dimensional code to the first gateway device G1 (S9).

  The first gateway device G1 stores the two-dimensional code in its own storage device (not shown).

  The first gateway device G1 transmits a selection menu including an icon to be selected when displaying the two-dimensional code to the display device 3 (S11). The selection menu includes device information g11 and storage location information indicating the storage location of the two-dimensional code.

  The display device 3 performs display based on the selection menu (S13).

FIG. 6 is a diagram illustrating a display example of the selection menu.
The selection menu MN includes an icon ICQ to be selected when displaying a two-dimensional code, and an icon IC0 to be selected when displaying a file in the storage device G11.

  If the icon ICQ is selected by remote control operation, the display device 3 transmits the storage location information to the first gateway device G1, acquires the two-dimensional code from the first gateway device G1, and displays it (S15).

FIG. 7 is a diagram illustrating a display example of a two-dimensional code.
For example, the display device 3 displays the acquired two-dimensional code (QR code) 100 instead of the icon ICQ.

  If the icon IC0 is selected in FIG. 6, the display device 3 transmits, for example, a command based on the device information g11 to the first gateway device G1, thereby obtaining the first gateway device G1 from the storage device G11. Information is acquired, thereby displaying the arrangement of the file in the storage device G11. If a desired file is selected by remote control operation, the file is acquired and displayed in the same manner.

  The two-dimensional code reader 5 takes a two-dimensional code (S17) and converts it to the original access key (S19).

  The two-dimensional code reader 5 accesses the control server 1 by the URL in the access key, and transmits the argument in the access key and the identification information of the two-dimensional code reader 5 to the control server 1 (S21).

  In the control server 1, the terminal device information acquisition unit 13 obtains a character string by hashing the authentication information stored in the authentication information storage unit 12 with the hash function H, and does not match the transmitted argument, or If the expiration timing of the expiration date associated with the authentication information has passed, the process ends. On the other hand, if the character string matches the argument and the expiration date has not passed, the terminal device information acquisition unit 13 obtains the transmitted identification information from the gateway device address storage unit 21 of the database server 2. The record that contains it is searched, and the global IP address in the record is acquired (S23). Here, the global IP address of the second gateway device G2 is acquired.

  In addition, when there are a lot of authentication information, it is preferable to perform hashing only for authentication information corresponding to information for which the expiration date of the expiration date has not passed, and reduce the number of times of hashing.

  The terminal device information acquisition unit 13 requests the gateway device having the global IP address (second gateway device G2) to transmit the terminal device information (S25). This request is also a request for various settings in the second gateway device G2, and the global IP address of the first gateway device G1 is notified.

  In response to this, the second gateway apparatus G2 performs various settings, that is, so-called NAPT (Network Address Port Translation) settings, proxy settings, and firewall settings (S27). Here, if the DMP function is invalid, the second gateway device G2 also makes a setting for enabling it.

  The port number “500” is an unused port number for the storage device 4, and may be another number if not used. Such a port number may be determined in advance.

  For the proxy setting, the second gateway device G2, for example, the set of the transmitted global IP address “10.10.1.1.1” and port number “400” of the first gateway device G1, the second gateway device G2 A pair of the local IP address “192.168.100.1” and the port number “200” is stored in association with each other.

  The port number “400” is an unused port number for the display device 3, and may be another number if not used. Such a port number is preferably determined in advance.

  Further, the second gateway apparatus G2 sets the firewall so that packets including the global IP address “10.10.1.1.1” of the first gateway apparatus G1 as the transmission source address are allowed to pass.

  Further, the second gateway device G2 transmits a search packet in the first home network N1 by the enabled DMP function.

  In response to this, the storage device 4 transmits storage location information indicating the storage location of the terminal device information 41 to the second gateway device G2.

  The second gateway device G2 transmits the storage location information to the storage device 4, and acquires the terminal device information 41 from the storage device 4 (FIG. 5: S29).

  The terminal device information acquisition unit 13 of the control server 1 acquires the terminal device information 41, the port number “400” for the display device 3, and the port number “500” for the storage device 4 from the second gateway device G2 (S31). ).

  The terminal device information acquisition unit 13 transmits the terminal device information 41, the port numbers “400” and “500”, and the global IP address of the second gateway device G2 to the first gateway device G1 (S33).

  In response to this, the first gateway device G1 performs various settings, that is, so-called NAPT setting, proxy setting, and firewall setting (S35).

FIG. 9 is an explanatory diagram of the NAPT and proxy settings in the first gateway device G1.
For example, the first gateway device G1 sets the NAPT setting by assigning a set of the global IP address “10.10.1.1.1” and the port number “400” assigned to itself to the local IP address “ A pair of “192.168.0.2” and port number “400” is stored in association with each other.

  Further, the first gateway apparatus G1 sets the firewall so as to pass a packet including the global IP address “200.20.2.2” of the second gateway apparatus G2 as a transmission source address.

  Then, the first gateway device G1 transmits a selection menu including an icon to be selected when displaying the file in the storage device 4 to the display device 3 (S41). The selection menu includes terminal device information 41.

  The display device 3 performs display based on the selection menu (S43).

FIG. 10 is a diagram illustrating a display example of the selection menu.
The selection menu MN1 includes an icon IC1 to be selected when displaying a file in the storage device 4, and an icon IC0 to be selected when displaying a file in the storage device G11.

  Thereafter, the display device 3 and the storage device 4 communicate with each other via the first gateway device G1 and the second gateway device G2 (S45). For example, the display device 3 displays a file in the storage device 4.

  For example, if the icon IC1 is selected, the display device 3 notifies the first gateway device G1 to that effect.
