  • Patent number: 8774597
    Abstract: An information processing apparatus includes a playback controller and a storage unit. The playback controller reads per-disc or per-title identification information in the form of a media ID recorded onto a disc, and then executes content playback selection processing or determines a playback processing mode according to bit information included in the media ID. The storage unit stores a program that causes the processing of the playback controller to be executed. By thus using the media ID, provided services, such as the content authorized for playback, can be modified.
