no. 1 Embodiment approach

[0076] Next, an embodiment of the playback device 200 of the present invention will be described.

[0077] FIG. 1 is a diagram showing a mode of use of the playback device 200 of the invention. The playback device 200 forms a home theater system together with the playback device 200 , the remote controller 300 , and the television 400 . The provision server 500 is a server device that provides application programs via a network. Among the application programs provided by the providing server 500, there are application programs with added area codes and digital signatures (hereinafter referred to as "recognized application programs") and applications without area codes and digital signatures (hereinafter referred to as "non-approved application programs"). program'.). The digital signature attached to the recognized application program is an X.509 certificate. The recognized application program utilizes the certification of the digital signature to verify whether the producer...

no. 2 Embodiment approach

[0133] In the first embodiment, the linkage conditions are recorded on the BD-ROM. The second embodiment is an embodiment in which linkage conditions are held in the playback device 200 .

[0134] FIG. 9 is a diagram showing the internal configuration of a playback device 200 according to the second embodiment. The playback device 200 of the second embodiment has a configuration in which the condition information storage unit 13 is added to the configuration in FIG. 3 .

[0135] The condition information holding unit 13 stores provider condition information for each content provider.

[0136] FIG. 10 is a diagram showing the configuration of provider condition information stored in the condition information storage unit 13 . Each provider condition information is data in which a 'provider ID' for uniquely identifying a content provider is added to the condition information recorded in the BD-ROM in Embodiment 1.

[0137] In the lead-in area of ​​the BD-ROM according to this...

no. 3 Embodiment approach

[0141] The playback device 200 according to the first embodiment, after playing back content in response to the user's operation on the remote controller 300 , estimates an application area of ​​an unapproved application and controls linked playback. On the contrary, in the third embodiment, when the application is acquired, the application area of ​​the non-approved application is estimated, and whether linked playback is possible or not is judged.

[0142] After the application is acquired, the network device 2 accesses the address input by the user or the address recorded in the BD-ROM 100 . If the access target is a providing server, the network device 2 downloads the application program, but uses the settings of the access target server to request a jump to another address, and provides the application program from the jump target server.

[0143] In this case, regardless of whether the address entered by the user or the ccTLD of the address recorded in the BD-ROM 100 is ...

Abstract

A reproduction device reproduces a content recorded on an optical disc while correlating it with execution of an application supplied from a server. The reproduction device includes: a disc region detection unit (2) for detecting a region code from the optical disc; an application estimation unit (9) for estimating a region code allocated to the application from a server address; and a limit unit (12) for limiting reproduction of the content correlated with the execution of the application if the region code allocated to the reproduction device itself, the region code detected from the optical disc, and the estimated region code of the application do not coincide.

Description

technical field [0001] The present invention relates to a content reproducing device, and in particular to a technique for reproducing content recorded on an optical disc in conjunction with an application program. Background technique [0002] In the BD-ROM playback device, an application downloaded from a server device on the network (hereinafter simply referred to as an "application") can be played back in association with the content recorded on the BD-ROM. Through this process, a new way of enjoying the content recorded on the BD-ROM can be created. This kind of viewing method does not exist in the existing DVD-Video, and it is doubtful for manufacturers of BD-ROM playback devices to expand the viewing method linked to the Internet to more households and popularize BD-ROM playback devices. [0003] As a related technique, Patent Document 1 and Patent Document 2 disclose a technique for jointly reproducing data recorded on an optical disk and data received from a server...
