摘要： In a right management server (100), a license data generation/updating unit (307) generates license data (900) including a use condition (503) for permitting a user to use a content based on a content use right (500) owned by the user. A subset use condition setting unit (308) sets a subset use condition (901) for temporarily invalidating the license data (900) in the license data (900). A communication unit (311) transmits the license data (900) in which the subset use condition (901) is set to the user terminal (110), and receives the license data (900) returned from the user terminal (110). Upon receipt of the invalidated license data (900), the license data generation/updating unit (307) cancels the invalidation of the license data (900) by updating the subset use condition (901).

摘要： A content distribution system distributes a content key and content use conditions for controlling a content use in a client apparatus to the client apparatus, via a communication channel, from either a multicast distribution server or a unicast distribution server. A content distribution management server determines by which distribution method to send the content key and content use conditions of each content according to an attribute of the content (a compression format, a compression ratio, a content holder, and the like). An encrypted content distribution server distributes only encrypted content whose content key and content use conditions are to be distributed by the unicast, and the multicast distribution server distributes encrypted content whose content key and content use conditions are superimposed by the multicast.

摘要： A transmission apparatus includes a license data input unit accepting an input of license data which permits reproduction of a storage content linked from a streaming content; a multiplexer generating multiplexed data by multiplexing the inputted license data on a broadcast content for a predetermined period of time; and an output unit transmitting the generated multiplexed data to a content reproduction apparatus via digital broadcast. The content reproduction apparatus includes a receiving unit receiving multiplexed data; a demultiplexer extracting license data and a broadcast content from the received multiplexed data; and a content reproduction unit reproducing the extracted broadcast content, and when obtaining a storage content whose reproduction is permitted based on the extracted license data, reproducing the obtained storage content based on the license data by switching the reproduction from the broadcast content to the storage content.

摘要： The present invention is directed to an information processing apparatus adapted for processing contents provided by contents distribution service. To contents distributed by a contents server (12), a sublicense which prescribes utilization conditions of the respective contents is added. From a license server (13), a main license which prescribes utilization condition of the entirety of contents distributed via channel that user contracts is provided. When it is instructed that contents are reproduced, reproduction of contents is permitted at a receiver (15) in the case where utilization conditions prescribed by the sublicense and the main license are both satisfied.

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.
