Abstract: A content receiver comprises: an acceptance unit for accepting a designation of a recording medium to which contents are to be output; a license information acquiring unit for acquiring output license information describing the output requirements of the contents; and an output unit for outputting the contents to the designated recording medium. The output license information includes usage time limit information indicating the time limit of using the contents in an output destination. The output unit acquires the usage time limit information from the output license information for the contents, and sets the acquired usage time limit information to a management information storing area in the designated recording medium, thereby managing the time period of using the contents in the recording medium even if the copyright protection of the recording medium, which is an export destination, has a function to manage the time period of using the contents.

Abstract: A device renders content on a medium by obtaining a table from the medium, obtaining a device key (DK) of the device and an index value of such (DK), indexing into an entry of the table based on the obtained index value, selecting an encrypted secret from the indexed-into entry, applying the obtained device key (DK) to the selected encrypted secret to expose the secret, and applying the exposed secret to render the content.
