(Authentication recommended processing)
Next, referring to FIGS. 6 and 7 for the flow of authentication recommendation processing that prompts (recommends) the optical disc player 10 to authenticate the disc ID of the optical disc 20 when the optical disc 20 is inserted into the optical disc player 10. To explain. FIG. 6 is a flowchart showing a flow of authentication recommendation processing in the optical disc player 10 according to the present embodiment. FIG. 7 is a diagram showing an example of a screen for notifying an outline of recommended authentication and conditional services displayed on the monitor 30 by the optical disc player 10 according to the present embodiment.

As shown in FIG. 6, when the optical disc 20 is inserted into the optical disc player 10 (step S100), the title key management unit 113 of the optical disc player 10 indicates that the title key associated with the disc ID of the optical disc 20 is the relevant optical disc player 10. It is determined whether or not it is managed at step S102. Specifically, the title key management unit 113 first acquires the disc ID of the optical disc 20 acquired by the disc information acquisition unit 111 from the disc ID management unit 112. Then, the title key management unit 113 manages the title key associated with the disc ID by determining whether the title key associated with the acquired disc ID is stored in the recording unit such as the HDD 13. It is determined whether or not. In step S102, the title key management unit 113 acquires the disc ID of the optical disc 20 acquired by the disc information acquisition unit 111 from the disc ID management unit 112. Therefore, the disc information acquisition unit 111 executes step 100 or step 102. The disk ID is acquired from the optical disk 20 (optical disk identification information acquisition step).

When it is determined that the title key is not managed (in other words, when the optical disk 20 is not authenticated by the acquired disk ID) (NO in step S102), the title key management unit 113 determines the disk ID of the optical disk 20. Notification is made to prompt the user to request the server 50 for authentication (step S104). Specifically, the title key management unit 113 controls the display control unit 118 to display on the monitor 30 an authentication recommendation screen that prompts the user to request the server 50 to authenticate the disc ID of the optical disc 20.

Also, the service providing unit 117 notifies the user of service summary information indicating a summary of conditional services that the user can receive when the disc ID of the optical disc 20 is authenticated (step S106). Specifically, the service providing unit 117 controls the display control unit 118 to display a screen (service summary information screen) for notifying service summary information on the monitor 30. Here, in the present embodiment, the notification of service summary information accepts a service summary information notification (service summary screen) for displaying a summary of each service, and a user instruction for checking the service summary screen. This includes notification of a service summary confirmation UI. Since the service providing unit notifies the user of the service overview information in step S106, the service providing unit acquires the service overview information before notifying the user of the service overview information (service overview information acquiring step).

For example, as shown in FIG. 7A, both the authentication recommendation screen and the service summary screen may be displayed in one screen, or as shown in FIG. 7B, the authentication recommendation screen and the service summary are displayed. When the confirmation UI is displayed and the service summary confirmation UI is selected, the service summary screen may be further displayed, and the display mode is not particularly limited. On the service summary screen, as shown in FIG. 7A, a summary of services (service title, brief description, icon indicating services, etc.) may be displayed as a list. The content is not particularly limited. In this manner, the display control unit 118 displays the authentication recommendation screen and notifies the user of the service summary information (notification step).

When the authentication recommendation screen is displayed, the title key management unit 113 displays a user instruction to authenticate the optical disk 20 by transmitting the disk ID to the server (a user instruction to request the server 50 to authenticate the disk ID). ) Is determined (authentication request is instructed) (step S108). For example, the title key management unit 113 can determine that the user instruction has been made when the operation signal acquisition unit 116 receives a user instruction to request authentication.

When it is determined that the authentication request is instructed by the title key management unit 113 (YES in step S108), the authentication request unit 114 transmits the disc ID of the optical disc 20 to the server 50 and also sends the disc ID to the server 50. Authentication is requested (step S110). And the authentication result acquisition part 115 acquires the authentication result of disk ID output from the server 50 (step S112).

When the acquired authentication result indicates that the disc ID is authenticated (that is, when the title key is acquired as the authentication result), the service providing unit 117 starts providing a conditional service.

As described above, in the present embodiment, the authentication recommendation process is performed when the optical disc 20 is inserted into the optical disc player 10. In this configuration, when the optical disc drive 16 detects the insertion of the optical disc 20, the CPU 11 controls the respective units such as the disc information acquisition unit 111, the title key management unit 113, the service providing unit 117, and the display control unit 118. It only has to function as a part.

In the present embodiment, the configuration in which the CPU 11 operates each unit when the optical disc drive 16 detects the insertion of the optical disc 20 is described as an example. However, the timing at which the CPU 11 operates each unit is determined by the optical disc drive 16 of the optical disc 20. If it is after detecting insertion, it will not specifically limit.

<Configuration subject to device ID authentication>
In the above example, the conditional service is provided on condition that the disk ID of the optical disk 20 is authenticated, but this does not limit the present embodiment. The conditional service may be provided on the condition that both the disc ID of the optical disc 20 and the device ID (device identification information) of the optical disc player 10 are authenticated. Here, the device ID is information for identifying the optical disc player 10 that requires authentication from other devices.

In this configuration, the authentication request unit 114 of the optical disc player 10 further transmits the device ID of the optical disc player 10 to the server 50 via the communication I / F 14 and further requests authentication of the device ID. . Further, the authentication result acquisition unit 115 acquires the authentication result of the device ID from the server 50 via the communication I / F 14. The service providing unit 117 provides a normal service and a conditional service when both the disk ID and the device ID are authenticated. If at least one of the disk ID and the device ID is not authenticated, the service providing unit 117 Only provide.

More specifically, the information acquisition unit 511 of the server 50 further receives a device ID authentication request via the communication I / F 54, and the authentication unit 512 further authenticates the acquired device ID. For example, the authentication unit 512 determines whether or not the acquired device ID is registered in a black list (BL) that manages unauthorized devices and the like using a list. If the device ID is registered in the BL, an authentication result indicating that the device has not been authenticated is output. Here, the BL includes a device BL that manages the device ID of an unauthorized device by a list, a disk BL that manages a disk ID of an unauthorized optical disc by a list, and the like.

In step S104, the title key management unit 113 may notify the user to request the server 50 to authenticate the disc ID of the optical disc 20 and the device ID of the optical disc player 10.

In step S106, the service providing unit 117 notifies service outline information indicating an outline of conditional services that the user can receive when both the disk ID of the optical disc 20 and the device ID of the optical disc player 10 are authenticated. To do.

In step S110, the authentication request unit 114 further requests the server 50 to authenticate the device ID. In step S112, the authentication result acquisition unit 115 acquires the authentication result of the disk ID and the device ID output from the server 50.

When the acquired authentication result indicates that the disk ID and the device ID are authenticated (that is, when the title key is acquired as the authentication result), the service providing unit 117 starts providing a conditional service.

[Embodiment 2]
Note that the timing of the authentication recommendation process in the optical disc player 10 is not limited to when the optical disc 20 is inserted into the optical disc player 10.

For example, the optical disc player may execute the authentication recommendation process at the timing of reproducing the content stored on the optical disc 20, or the authentication recommendation process at the timing of obtaining a user instruction for instructing provision of a conditional service. May be.

[Embodiment 3]
In the present embodiment, the configuration in which the optical disc player 10 realizes the notification for prompting the user to authenticate by displaying the authentication recommendation screen has been described as an example. However, the notification method is not limited to this. For example, it is possible to employ a configuration in which notification is made by voice or the like.

When displaying the service summary information screen, the service providing unit 117 may obtain the service summary from, for example, the HDD 13 or from the optical disc 20 set in the optical disc player 10. Alternatively, it may be acquired via an external network such as the server 50. When the service summary is acquired from the server 50, the service management unit 513 of the server 50 also functions as an output unit, and the service summary may be output to the optical disc player 10 via the communication I / F 54.

[Embodiment 4]
Further, when there is a problem that the optical disk player 10 cannot request the server 50 to authenticate the disk ID when the optical disk 20 is inserted, the notification that prompts the user to request the server 50 to authenticate the disk ID. As such, notification of prompting to solve the problem may be sent.

For example, when the optical disc player 10 is not connected to the network 70 (in other words, when the disc ID cannot be transmitted to the server 50), the optical disc player 10 requests the server 50 to authenticate the disc ID. The notification prompting the user to connect the optical disc player 10 to the network 70 may be notified.

According to this, even if there is a problem that the optical disk player 10 cannot request the server 50 to authenticate the disk ID, the optical disk player 10 notifies the user of this and resolves it, so that the disk 50 Authentication can be requested. Therefore, the optical disk player 10 can provide a conditional service to the user even when there is a problem that the server 50 cannot request the disk ID authentication when the optical disk 20 is inserted.

Note that when the user resolves the problem in accordance with the notification that prompts the user to resolve the problem, the optical disk player 10 may automatically request the server 50 to authenticate the disk ID, or authenticate the disk ID. Notification that prompts the user to request the server 50 may be performed again.

In the above-described embodiment, the configuration in which the playback apparatus is realized by the optical disc player 10 that does not include a display (monitor) has been described as an example. However, the present invention is not limited to this. For example, the playback apparatus may employ a configuration realized by a television receiver having the configuration of the display and the optical disc player 10 described above, or a PC.

[Embodiment 5]
