Content receiving device, and content distribution system
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.

a meta-information acquiring unit that acquires meta-information having output times information showing times which can output the contents to the storage medium;
characterized in that:
the output license information has usage conditions information indicating usage conditions of the contents in an output destination;
in the case of the export after recording, the download microprocessor stores the downloaded contents in the storage memory; the output microprocessor outputs the contents stored in the storage memory to the external storage medium; acquires the usage conditions information from the output license information for the contents; and sets the acquired usage conditions information in a management information storing area in the external storage medium;
in the case of the direct export, the output microprocessor outputs the downloaded contents by the download microprocessor to the external storage medium, without storing in the storing memory; the output microprocessor acquires the usage conditions information from the output license information for the contents and sets the acquired usage conditions information in a management information storing area in the external storage medium;
the output license information has, as the usage conditions information, usage time limit information indicating usage time limit of the contents in an output destination;
the output microprocessor executes output of the contents, on times indicated in the output times information, and sets the usage time limit information acquired from the output license information, and times corresponding to the output times information acquired from the meta-information in a management information storing area in the external storage medium.
2. The content receiver apparatus according to claim 1 , characterized in that:
in the case of the export after recording, when the output microprocessor outputs the contents from the storage memory to the external storage medium, the license information acquiring microprocessor acquires the output license information;
in the case of the direct export, when the download microprocessor downloads the contents, the license information acquiring microprocessor acquires the output license information.
3. The content receiver apparatus according to claim 1 , characterized in that:
the output license information has, as the usage conditions information, usage time limit information indicating usage time limit of the contents in an output destination;
the output microprocessor acquires the usage time limit information from the output license information, and sets the acquired usage time limit information, in a management information storing area in the external storage medium.
4. The content receiver apparatus according to claim 1 , characterized in that:
the output microprocessor acquires the output times information from the meta-information, and sets times corresponding to the acquired output times information in a management information storing area in the external storage medium.
5. A content output method for a content receiver apparatus comprising:
executing download of contents;
storing the downloaded contents in a storage memory;
acquiring output license information describing output requirements of the contents;
outputting the contents to an external storage medium, by export after recording the contents, or by direct export;
acquiring meta-information having output times information showing times which can output the contents to the storage medium;
characterized in that:
the output license information has usage conditions information indicating usage conditions of the contents in an output destination;
in the case of the export after recording, storing the downloaded contents in the storage unit; outputting the stored contents in the storage memory to the external storage medium, acquiring the usage conditions information from the output license information for the contents, and setting the acquired usage conditions information in a management information storing area in the external storage medium;
in the case of the direct export, outputting the downloaded contents, without storing in the storage memory, and acquiring usage conditions information from the output license information for the contents, setting the acquired usage conditions information in a management information storing area in the external storage medium;
the output license information has, as the usage conditions information, usage time limit information indicating usage time limit of the contents in an output destination;
executing output of the contents, based on times indicated in the output times information, and setting the usage time limit information acquired from the output license information, and times corresponding to the output times information acquired from the meta-information in a management information storing area in the external storage medium.
6. The content output method according to claim 5 , characterized in that:
in the case of the export after recording, when outputting the contents from the storage unit to the external storage medium, acquiring the output license information;
in the case of the direct export, when downloading the contents, acquiring the output license information.
7. The content output method according to claim 5 , characterized in that:
the output license information has, as the usage conditions information, usage time limit information indicating usage time limit of the contents in an output destination;
acquiring the usage time limit information from the output license information, and setting the acquired usage time limit information in a management information storing area in the external storage medium.
8. The content output method according to claim 5 , further comprising
acquiring the output times information from the meta-information, and setting times corresponding to the acquired output times information in a management information storing area in the external storage medium.
