Content distribution control
First Claim
1. A method for controlling content distribution over a network, the method comprising:
- generating content in a first format specification by adding content identification data for identifying specific content to data produced in a first format specification for viewing;
sending the content to a network;
receiving the content via the network;
separating the received content into the content identification data and the data in the first format specification;
converting the separated data in the first format specification to data in a second format specification that is different from the first format specification;
generating content in a second format specification by adding the separated content identification data to the data converted to the second format specification; and
sending the content in the second format specification to a user terminal.

Abstract
Content distribution control over a network in an electronic distribution system protects the content copyright while distributing content in a format enabling viewing and enjoyment at the user terminal. The method for controlling content distribution over a network comprises generating content in a first format specification by adding content identification data for identifying specific content to data produced in a first format specification for viewing; sending the content to a network; receiving the content via the network; separating the received content into the content identification data and the data in the first format specification; converting the separated data in the first format specification to data in a different, second format specification; generating content in a second format specification by adding the separated content identification data to the data converted to the second format specification; and then sending the content in the second format specification to a user terminal.

5. A system for controlling content distribution over a network, the system comprising:
-
a first identification data adding unit for generating content in a first format specification by adding content identification data for identifying specific content to data produced in a first format specification for viewing and then sending the content to a network;
an identification data separating unit for receiving the content from the first identification data adding unit via the network, and separating the received content into the content identification data and the data in the first format specification;
a converter for converting data in the first format specification separated by the identification data separating unit to data in a second format specification that is different from the first format specification; and
a second identification data adding unit for generating content in a second format specification by adding the content identification data separated by the identification data separating unit to the data to the data converted to the second format specification by the converter, and then sending the content in the second format specification to a user terminal. - View Dependent Claims (6, 7, 8, 9)

10. A computer-executable program for controlling content distribution, the program comprising:
-
generating content in a first format specification by adding content identification data for identifying specific content to data produced in a first format specification for viewing;
sending the content to a network;
receiving the content via the network;
separating the received content into the content identification data and the data in the fi r st format specification;
converting the separated data in the first format specification to data in a second format specification that is different from the first format specification;
generating content in a second format specification by adding the separated content identification data to the data converted to the second format specification; and
sending the content in the second format specification to a user terminal. - View Dependent Claims (11, 12, 13, 14, 16)

15. A method for relaying content distributed over a network, the method comprising:
-
receiving content via the network, where the content is generated in a first format specification by adding content identification data for identifying specific content to data produced in a first format specification for viewing;
separating the received content into the content identification data and the data in the first format specification;
converting the separated data in the first format specification to data in a second format specification that is different from the first format specification;
generating content in a second format specification by adding the separated content identification data to the data converted to the second format specification; and
sending the content in the second format specification to a user terminal.
