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.
