At this time, when the common key cryptosystem is used, the encryption key 205 is used as the decryption key 302. When the public key cryptosystem is used, the decryption key 302 is generated by the two-dimensional code generation unit 108 and stored in the nonvolatile storage unit 110 in the same manner as the encryption key 205 at the time of encryption. These means can be arbitrarily selected by a program provided in the ROM 102 when the two-dimensional code 203 is generated.

  FIG. 4 is a diagram illustrating an example of a two-dimensional code display method of the video reproduction device according to the first embodiment. In FIG. 4, a cell 402 is one square area constituting the two-dimensional code 401, and each cell is designated as a contrast color having a bright contrast such as white and black. In FIG. 4, as an example, a dot 403 on the screen for expressing each cell is set to one cell in units of 4 × 4 dots. The display device 105 is, for example, 1920 × 1080 dots when full HD (Full High Definition) can be displayed, and is square when the square still image generated by the AV decoder 104 is displayed on the display device 105. The power shape is displayed as a horizontally long rectangle having an aspect ratio of 9:16. In order to display an image of a square two-dimensional code on such a display device 105 (two-dimensional code 404 on the right side of FIG. 4), a cell of the two-dimensional code 401 generated at the time of conversion by the two-dimensional code generation means 108 It is necessary to convert the aspect ratio of each dot as an ellipse of 16: 9 so as to constitute a cell 402 having an aspect ratio of 16: 9 (two-dimensional code 401 on the left side of FIG. 4). By displaying the dots in this way, the aspect ratio of the image of the two-dimensional code displayed on the display device 105 can be 1: 1 (square). The ratio change means 101d of the CPU 101 changes the aspect ratio. The processing content by the ratio changing unit 101d can be arbitrarily selected by a program included in the ROM 102 when the two-dimensional code 401 is generated, for example, when display device information is input from the remote controller 302. Therefore, if the aspect ratio information of the screen of the display device 105 is held, the aspect ratio of the two-dimensional code can be arbitrarily changed regardless of the aspect ratio of the screen.

  FIG. 5 is a flowchart showing user registration processing by the video reproduction apparatus 100 according to the first embodiment. Based on FIG. 5, an example of a procedure for performing communication with a content provider related to content included in the large-capacity optical disk 106 when a predetermined condition is satisfied will be described.

  The video playback apparatus 100 plays back the content stored on the large-capacity optical disk 106 according to the scenario A that defines the playback order (step S201), and when the playback according to the scenario A is completed, the playback is performed according to the scenario B. A transition is made (step S202). As described above, some large-capacity optical discs 106 are configured to be able to transition to reproduction according to the next scenario only when reproduction according to a predetermined scenario is completed. In the example of FIG. 5, a predetermined condition is satisfied by completing reproduction according to scenario C (step S204), reproduction according to scenario D (step S205), and reproduction according to scenario E (step S206) in this order. As a result (step S203), the process can proceed to step S207. The video reproduction apparatus 100 determines whether or not the user registration related to the content of the large-capacity optical disk 106 has been performed (step S207). If the user registration has not been performed, the server connection address (Internet connection destination information 201) is acquired. (Step S208), the process proceeds to user registration.

  When the video reproduction apparatus 100 obtains the connection address of the server 501 (step S208), the two-dimensional code generation means 108 converts the Internet connection destination information 201 into the two-dimensional code 203 and displays it on the display apparatus 105 (step S208). Step S209). Thereafter, the two-dimensional code is photographed by using the camera-equipped mobile terminal device 301, the Internet connection destination information 201 is restored (step S210), the server on the Internet is accessed (step S211), and the contents of the large-capacity optical disk 106 are obtained. User registration is performed (step S212). The Internet connection destination information 201, the two-dimensional code 203, and information related to user registration are transmitted from the mobile terminal device 301 to the video display device 100 using infrared communication means, and the next time the large-capacity optical disk 106 is reproduced. Therefore, it can be stored in the nonvolatile storage means 110.

  FIG. 6 is a flowchart showing hidden scenario playback processing by the video playback apparatus 100 according to Embodiment 1. The video playback device 100 plays back according to scenario A when playing back the content stored on the large-capacity optical disk 106 (step S301), and transitions to playback according to scenario B when playback according to scenario A is completed. (Step S302). Similar to the example of FIG. 5, there is content that can transition to playback according to the next scenario only when playback according to a predetermined scenario is completed. When the reproduction according to the predetermined scenario is completed (step S303), the video reproduction apparatus 100 requests a remote control operation for reproducing the hidden scenario. For example, the direction keys of the remote control are arranged in a predetermined order (for example, “up, down, down, right, right, left” or numerical passwords “1, 3, 5, 7, 9”, etc.). By performing the operation, it is possible to reproduce according to the hidden scenario when the condition of step S303 is satisfied (step S311). In this example, the condition is satisfied by sequentially completing the reproduction according to the scenario C (step S305), the reproduction according to the scenario D (step S306), and the reproduction according to the scenario E (step S307) (step S307). S304), the process can proceed to step S308. If the reproduction according to scenario C (step S305) is not completed, the transition to the reproduction according to scenario D (step S306) does not occur. If the reproduction according to scenario D (step S306) is not completed, scenario E is followed. When the transition to the reproduction (step S307) does not occur and the reproduction according to the scenario E (step S307) is completed, the server connection address (Internet connection destination information 201) is acquired (step S308), and the hidden scenario is obtained. Therefore, the process shifts to the reproduction process.

  When the video reproduction device 100 obtains the connection address of the server 501 (step S308), the two-dimensional code generation means 108 converts the Internet connection destination information 201 into the two-dimensional code 203 and displays it on the display device 105 ( Step S309). Thereafter, a two-dimensional code is photographed by using the camera-equipped mobile terminal device 301, the Internet connection destination information 201 is restored (step S310), a server on the Internet is accessed (step S311), and the hidden scenario reproduction operation procedure Is acquired (step S312). Internet connection destination information 301, two-dimensional code 303, and information regarding the playback operation procedure of the hidden scenario are transmitted from the mobile terminal device 301 to the video display device 100 using infrared communication means, and then the large-capacity optical disk 106 is loaded.
