Abstract:
1. A terminal apparatus which processes a copyright-protected content based on a plurality of rights that permit the processing of the copyright-protected content, said terminal apparatus comprising: a priority information selecting unit configured to select a piece of priority information associated with one processing condition of a plurality of processing conditions for the copyright-protected content to be processed, the piece of priority information being selected from among a plurality of pieces of priority information for determining a priority for each right of the plurality of rights; a right selecting unit configured to determine the priority of each right of the plurality of rights based on the selected piece of priority information, and to select a right, of the plurality of rights, having a highest priority, the right being selected according to the determined priority of each right; a content processing unit including a processor configured to process the copyright-protected content based on the selected right; and a priority information management information generating unit configured to generate priority information management information indicating associations between the plurality of pieces of priority information and the plurality of processing conditions for the copyright-protected content, wherein the plurality of rights includes a first right specifying a first processing time, which is a length of time for which the processing of the copyright-protected content is permitted, and a second right specifying a first processing count, which indicates a number of times for which the processing of the copyright-protected content is permitted, wherein the plurality of pieces of priority information includes (i) first priority information indicating that the first processing time has a higher priority than the first processing count, and (ii) second priority information indicating that the first processing count has a higher priority than the first processing time, wherein said priority information management information generating unit is configured to (i) calculate a second processing count by dividing the first processing time by a second processing time required for processing the copyright-protected content according to a first processing condition which is a processing condition of the plurality of processing conditions of the copyright-protected content, (ii) compare the first processing count and the second processing count, (iii) generate the priority information management information in which the first priority information is associated with the first processing condition, when the second processing count is greater than the first processing count, and (iv) generate the priority information management information in which the second priority information is associated with the first processing condition, when the second processing count is less than the first processing count, and wherein said priority information selecting unit is configured to select, according to the priority information management information and from among the plurality of pieces of priority information, the piece of priority information associated with the one processing condition of the plurality of processing conditions for the copyright-protected content to be processed.
