Abstract
A playback apparatus judges whether a region code assigned to a BD-ROM matches a region code assigned to the playback apparatus. When the judgment result is in the affirmative, the playback apparatus plays back the content recorded on the optical disc. When the judgment result is in the negative, the playback apparatus does not play back the content, except when an exceptional playback is authorized. The exceptional playback is authorized when a combination of the content identifier of the content to be played back and the apparatus region code satisfies a predetermined condition defined by an owner of the rights of the content.
Claims7
A system comprising:
- an optical disc having a disc region code assigned thereto and having content and a content identifier identifying the content recorded thereon;
- and
- a playback apparatus for playing back the optical disc,
- wherein the playback apparatus comprises:
- a control unit programmed to judge whether the disc region code assigned to the optical disc matches an apparatus region code assigned to the playback apparatus;
- and
- a playback unit programmed to play back the content when the control unit judges that the disc region code matches the apparatus region code,
- wherein, the control unit is programmed such that, when the control unit judges that the disc region code does not match the apparatus region code, the control unit judges whether a combination of the content identifier and the apparatus region code satisfies a predetermined condition defined by an owner of rights of the content,
- wherein, the playback unit is programmed such that, when the control unit judges that the combination of the content identifier and the apparatus region code satisfies the predetermined condition defined by the owner of the rights of the content, the playback unit plays back the content recorded on the optical disc,
- wherein, the playback unit is programmed such that, when the control unit judges that the combination of the content identifier and the apparatus region code does not satisfy the predetermined condition defined by the owner of the rights of the content, the playback unit does not play back the content,
- wherein the playback apparatus further comprises a transmitting unit programmed to transmit an authorization request to a server apparatus on a network of an external system, the authorization request indicating the combination of the content identifier and the apparatus region code,
- wherein the server apparatus is programmed to transmit an authorization response when, based on the authorization request, the server apparatus has determined that the combination of the content identifier and the apparatus region code satisfies the predetermined condition, and
- wherein the server apparatus is programmed to transmit a non-authorization response when, based on the authorization request, the server apparatus has determined that the combination of the content identifier and the apparatus code does not satisfy the predetermined condition.
