    摘要: The management apparatus 105a manages copying of information from an original recording medium 101a to a copy recording medium 102a. The management apparatus 105a comprises: a transmission/reception unit 701a configured to receive an original-medium identifier from the copying apparatus 104a and to transmit permission information to the copying apparatus 104a, the original-medium identifier identifying the original recording medium, and the permission information indicating permission for the copying of the information; and a control unit 708a configured to determine whether to permit the copying of the information based on the received original-medium identifier and a registered original-medium identifier that identifies a registered original recording medium, and to allow the transmission/reception unit 701a to transmit the permission information when determining to permit the copying.

    摘要: Techniques are disclosed for deterring theft of media recording devices. Input received from a sensor, or some portion of the input, is encrypted prior to storing a media file. A decryption key must be provided when the media file is to be played back. If the key is not provided, then the file is preferably still played back, but is played back in a degraded manner. For example, a background color or other filler may be rendered in place of the encrypted portion. Additional parts of the file may also be degraded during playback. By making the playback unpleasant for the listener/viewer, theft of the recording device will be much less desirable—yet recording can continue uninterrupted, thereby minimizing disruption to legitimate users. The disclosed techniques may also be used to deter theft of the recorded media.

    摘要: A data processing apparatus is capable of playing back contents stored in a specified area in a recording medium. The recording medium stores content data and management information for managing the content data. When playing back a content which is managed by the management information on the recording medium but of which entity data is not present in the specified area of the recording medium, the data processing apparatus, searches, for the content, the other area of the recording medium with a search section. When the corresponding content is found, the link information selling section sets the link information (symbolic link, shortcut, etc.) on the recording medium so that the content can be accessed with the management information.
