CONTENT DISTRIBUTION SYSTEM

摘要

When a copyright management method reported from a client terminal (1) is different from a copyright management method which can be used by a license server (2) and a distribution server (4), the license server (2) requests a copyright management method conversion server (6) to convert the copyright management method in a multi-media content. When the copyright management method conversion server (6) receives the copyright management method conversion request, the conversion server (6) converts the copyright management method of the multi-media content distributed from the distribution server (4) into the copyright management method which can be used by the client terminal (1) and transmits the converted multi-media content to the client terminal (1).
