Abstract

A data distribution system and method suitably performing various processing such as suitable distribution of data, control of copying, conversion of signals, charging, and distribution of profits, comprising a reproducing apparatus for reproducing content data to be distributed from a mounted recording medium, a recording apparatus for recording reproduced content data on a mounted recording medium, an examining means for examining types of content data recorded on the recording medium, the recording medium mounted in the reproducing apparatus, the reproducing apparatus, a recording medium mounted in the recording apparatus and the recording apparatus, and a controlling means for controlling a transfer of the content data from the recording medium mounted in the reproducing apparatus to the recording medium mounted in the recording apparatus based on results of the examination.

Claims

1. A data distribution system comprising:

a reproducing apparatus for reproducing content data distributed from a first medium;

a recording apparatus for recording the reproduced content data on a second medium;

one or more processors for examining usage space information of the content data, the first medium, the reproducing apparatus, the second medium, and the recording apparatus; and

a controller for controlling transfer of the content data from the first medium to the second medium based on the result of the examination;

wherein the usage space information indicates system information of the recording apparatus and the reproducing apparatus, ownership right information of the content data, format information of the content data, and distributing profit information obtained by the distribution of the content data, and

wherein the one or more processors;

examines whether the content data is of a first type which is distributed in an encrypted state or of a second type which is distributed in an unencrypted state,

examines whether the first medium is of a first type having a configuration enabling recorded data to be effectively read out by performing authentication processing or of a second type having no such configuration and enabling read out of the recorded data without authentication,

examines the reproducing apparatus to determine whether the reproducing apparatus is of a first type for reproducing after the authentication processing or of a second type for reproducing without the processing, and

examines the recording apparatus to determine whether the recording apparatus is of a first type for recording after the authentication processing or of a second type for recording without the processing.

2. A data distribution system as set forth in claim 1, wherein the controller disables the reproduction when the usage information indicates that the content data is of the first type, the first medium is the second type of medium, and the reproducing apparatus is the second type of reproducing apparatus.

3. A data distribution system as set forth in claim 1, wherein the controller disables the reproduction when that the content data is of the first type, the first medium is the second type of medium, and the reproducing apparatus is the first type of reproducing apparatus.

4. A data distribution system as set forth in claim 1, wherein the controller enables the reproduction when the usage information indicates that the content data is of the second type, the first medium is the second type of medium, and the reproducing apparatus is the second type of reproducing apparatus.

5. A data distribution system as set forth in claim 1, wherein the controller enables the reproduction when the usage information indicates that the content data is of the second type, the first medium is the second type of medium, and the reproducing apparatus is the first type of reproducing apparatus.

6. A data distribution system as set forth in claim 1, wherein the controller disables the reproduction when the usage information indicates that the content data is of the first type, the first medium is the first type of medium, and the reproducing apparatus is the second type of reproducing apparatus.

7. A data distribution system as set forth in claim 1, wherein the controller enables the reproduction when the usage information indicates that the content data is of the first type, the first medium is the first type of medium, and the reproducing apparatus is the first type of reproducing apparatus.

8. A data distribution system as set forth in claim 1, wherein the controller enables the reproduction when the usage information indicates that the content data is of the second type, the first medium is the first type of medium, and the reproducing apparatus is the second type of reproducing apparatus.

9. A data distribution system as set forth in claim 1, wherein the controller enables the reproduction when the usage information indicates that the content data is of the second type, the first medium is the first type of medium, and the reproducing apparatus is the first type of reproducing apparatus.

10. A data distribution system as set forth in claim 1, wherein the controller disables the recording when usage information indicates that the content data is of the first type, the second medium is the second type of medium, and the recording apparatus is the second type of recording apparatus.

11. A data distribution system as set forth in claim 1, wherein the controller disables the recording when usage information indicates that the content data is of the first type, the second medium is the second type of medium, and the recording apparatus is the first type of recording apparatus.

12. A data distribution system as set forth in claim 1, wherein the controller enables the recording when the usage information indicates that the content data is of the second type, the second medium is the second type of medium, and the recording apparatus is the second type of recording apparatus.

13. A data distribution system as set forth in claim 1, wherein the controller enables the recording when the usage information indicates that the content data is of the second type, the second medium is the second type of medium, and the recording apparatus is the first type of recording apparatus.

14. A data distribution system as set forth in claim 1, wherein the controller disables the recording when that the content data is of the first type, the second medium is the first type of medium, and the recording apparatus is the second type of recording apparatus.

15. A data distribution system as set forth in claim 1, wherein the controller enables the recording when the usage information indicates that the content data is of the first type, the second medium is the first type of medium, and the recording apparatus is the first type of recording apparatus.

16. A data distribution system as set forth in claim 1, wherein the controller enables the recording when the usage information indicates that the content data is of the second type, the second medium is the first type of medium, and the recording apparatus is the second type of recording apparatus.

17. A data distribution system as set forth in claim 1, wherein the controller enables the recording when the usage information indicates that the content data is of the second type, the second medium is the first type of medium, and the recording apparatus is the first type of recording apparatus.

18. A data processing apparatus comprising:

a reproducing apparatus for reproducing content data distributed from a recording medium;

one or more processors for examining usage space information of the content data, the recording medium , and the reproducing apparatus; and

a controller for controlling the reproduction of the content data from the recording medium based on results of the examination;

wherein the usage space information indicates system information of the reproducing apparatus, ownership right information of the content data, format information of the content data, and distributing profit information obtained by the distribution of the content data, and
