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 in a service environment that provides the DRM content by using a plurality of incompatible DRM systems, the user terminal apparatus comprising:
- a transceiver;
a DRM agent for supporting a first DRM system; and
a DRM proxy server agent for acquiring, through the transceiver, a license corresponding to the DRM content from a service providing apparatus that provides the DRM content, determining whether the license is a common license having a common DRM interface format, converting the common DRM interface format of the common license to a format of the first DRM system installed in the user terminal apparatus when the license is the common license, and transferring the license to the DRM agent,wherein 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.

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 method of providing a Digital Rights Management (DRM) service by a user terminal apparatus consuming 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:
-
acquiring a license corresponding to the DRM content from a service providing apparatus that provides the DRM content; determining whether the license is a common license having a common DRM interface format; converting the common DRM interface format of the common license to a format of a first DRM system installed in the user terminal apparatus, when the license is the common license; and applying the license having the format of the first DRM system in reproducing the DRM content, wherein 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. - 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:
-
generating a license corresponding to the DRM content, wherein the license has a format of a first DRM system supported by the service providing apparatus; converting the format of the license to a common DRM interface format when a user terminal apparatus that is to receive the license is equipped with a second DRM system that is different than the first DRM system; and transmitting the license to the user terminal apparatus through a common DRM interface. - 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, 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 license has a format of the first DRM system; and a common domain manager for, when a user terminal apparatus that is to receive the license is equipped with a second DRM system that is different than the first DRM system, converting the format of the license to a common DRM interface format and transmitting the license to the user terminal apparatus through the common DRM interface. - View Dependent Claims (17, 18, 19, 20, 21)
