摘要： To provide a content playback device that can use content appropriately by avoiding output of content not permitted to be used according to contract information. A playback control unit 102 extracts a content name from playback control information in a playback path information table 210, and inquires of a rights management unit 108 whether content identified by the extracted content name is playable or not. If the content is judged as being unplayable, the playback control unit 102 extracts an alternative playback number from the playback control information, and extracts a content name from playback control information whose playback number matches the alternative playback number. The playback control unit 102 then instructs a decryption unit 103 and a playback unit 107 to decrypt and play back encrypted content identified by the extracted content name.

摘要： [Object] To realize a content receiving apparatus and the like which can avoid a situation where content cannot be reproduced even when content receiving routes are switched from a broadcast wave to a communication network at an arbitrary timing. [Means to achieve the object] A receiving route switch control unit (112) determinates which receiving route is selected from the broadcast wave (20) and the communication network (30) to obtain content, and switches receiving routes based on this determination. A DRM module (140) manages the copyright of the obtained content based on a digital rights management (DRM) method defined by a provider A when content is received via the broadcast wave (20). Likewise, a DRM module (150) manages the content of copyright based on a DRM method B defined by a provider B, and a DRM module (160) manages content copyrights based on a DRM method C defined by a provider C, respectively.

摘要： When a secure counter malfunction detection unit 212 deters a malfunction in a secure counter 211, a content playability judgment unit 206 performs a content playability judgment based on information managed by a malfunctioning-state playback processing management unit 214. The malfunctioning-state playback processing management unit 214 stores a malfunctioning-state playback condition composed of information such as a playback count and a playback time. The content playability judgment unit 206 judges that content is playable when the malfunctioning-state playback condition is met, and a content playback unit 210 splays the content.

摘要： An application management device 54 that is capable of judging the necessity of application deletion with little load includes: a DRM application DB 520 that stores plural applications in association with their respective identification information (DRM application IDs) for identifying a correspondence between a license and an application for processing such license; and a DRM application deletion judgment unit 527 that judges, for each of the applications stored in the DRM application DB 520, whether deletion of an application is necessary or not, based on the identification information. More specifically, the application management device 54 further includes a license DB 521 for storing each license in association with the identification information, and the DRM application deletion judgment unit 527 judges that an application whose license associated with the identification information is not stored in the license DB 521, is an application to be deleted.

摘要： A content playback apparatus reduces load concentration on a specific server apparatus that manages content keys of encrypted content, while protecting copyrights of the content. The content apparatus makes playback of content recorded in a recording medium sold possible after the specific server breaks down. A key acquisition control unit (204) reads a playback control information table (211) from a recording medium (102) via a reading unit (201). The key acquisition unit (204) acquires a rights key via a key acquisition intermediation unit (223) from an apparatus specified by an acquisition-destination type and a request-destination type that are stored in the playback control information table (211) and that corresponding to the content to be played. The key acquisition unit (204) generates a content key using the acquired rights key and, when required, a medium key recorded in a medium. A decryption unit (203) decrypts encrypted content using the content key.
