发明名称 CONTENT RECEIVING DEVICE, AND CONTENT DISTRIBUTION SYSTEM
摘要 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.
