Method and apparatus for providing DRM service
First Claim
1. A user terminal apparatus for consuming Digital Rights Management (DRM) content and providing a DRM service, the user terminal apparatus comprising:
- a transceiver for receiving a license corresponding to the DRM content from a service providing apparatus; and
a processor for;
transmitting a report message to the service providing apparatus, the report message including an identifier of the user terminal apparatus and information on a type of a first DRM system installed in the user terminal apparatus;
determining whether the received license is a common license having a common format for supporting DRM content which is not supported at the service providing apparatus;
converting the common format of the common license to a format of the first DRM system and transferring the converted license to a DRM agent of the user terminal apparatus, based on determining that the received license is the common license; and
transferring the received license to the DRM agent based on determining that the received license is not the common license.

Abstract
Methods and apparatus are provided for providing a DRM service by a user terminal apparatus consuming DRM content in a service environment that provides the DRM content using a plurality of incompatible DRM systems. A license corresponding to the DRM content is acquired from a service providing apparatus that provides the DRM content. It is determined whether the license is a common license having a common DRM interface format. The common DRM interface format of the common license is converted to a format of a first DRM system installed in the user terminal apparatus, when the license is the common license. The license having the format of the first DRM system is applied in reproducing the DRM content. The common license is provided from the service providing apparatus to the user terminal apparatus through a common DRM interface when the service providing apparatus does not support the first DRM system.

8. A user terminal apparatus for consuming Digital Rights Management (DRM) content and providing a DRM service, the user terminal apparatus comprising:
-
a DRM server agent configured for; transmitting a report message to a service providing apparatus, the report message including an identifier of the user terminal apparatus and information on a type of a first DRM system installed in the user terminal apparatus; acquiring a license corresponding to the DRM content from the service providing apparatus that provides the DRM content; determining whether the acquired license is a common license having a common format for supporting DRM content which is not supported at the service providing apparatus; converting the common format of the common license to a format of the first DRM system and transferring the converted license to a DRM agent of the user terminal apparatus, based on determining that the acquired license is the common license; and transferring the acquired license to the DRM agent based on determining that the acquired license is not the common license. - View Dependent Claims (9, 10, 11)

12. A method of providing a Digital Rights Management (DRM) service by a service providing apparatus that provides DRM content in a service environment that provides the DRM content by using a plurality of incompatible DRM systems, the method comprising the steps of:
-
receiving a report message from a user terminal apparatus, the report message including an identifier of the user terminal apparatus and information on a type of a second DRM system installed in the user terminal apparatus; registering the user terminal apparatus in the service providing apparatus; generating a license corresponding to the DRM content, wherein the generated license has a format of a first DRM system supported by the service providing apparatus; determining whether a user terminal apparatus that is to receive the generated license, through a DRM proxy server agent that is a common DRM interface between the service providing apparatus and the user terminal apparatus, is equipped with the second DRM system that is different from the first DRM system, based on the information on the type of the second DRM system installed in the user terminal apparatus; converting the format of the generated license to a format of the common DRM interface and transmitting the converted license to the user terminal apparatus through the common DRM interface, based on determining that the user terminal apparatus is equipped with the second DRM system; and transmitting the generated license to the user terminal apparatus based on determining that the user terminal apparatus is not equipped with the second DRM system. - View Dependent Claims (13, 14, 15)

16. A service providing apparatus for providing Digital Rights Management (DRM) content and providing a DRM service in a service environment that provides the DRM content by using a plurality of incompatible DRM systems, the service providing apparatus comprising:
-
a service provider for storing information on types of DRM systems installed in a plurality of user terminal apparatuses; a DRM server for supporting a first DRM system and generating a license corresponding to the DRM content, wherein the generated license has a format of the first DRM system; and a common domain manager for; receiving a report message from a user terminal apparatus, the report message including an identifier of the user terminal apparatus and information on a type of a second DRM system installed in the user terminal apparatus; registering the user terminal apparatus in the service providing apparatus; determining whether the user terminal apparatus that is to receive the generated license is equipped with the second DRM system that is different from the first DRM system, based on the information on the type of the second DRM system installed in the user terminal apparatus; converting the format of the generated license to a format of a common DRM interface and transmitting the converted license to the user terminal apparatus through the common DRM interface based on determining that the user terminal apparatus that is to receive the generated license, through a DRM proxy server agent that is the common DRM interface between the service providing apparatus and the user terminal apparatus, is equipped with the second DRM system that is different from the first DRM system; and transmitting the generated license to the user terminal apparatus based on determining that the user terminal apparatus is not equipped with the second DRM system. - View Dependent Claims (17, 18, 19, 20, 21)
