摘要： Disclosed is a method and an apparatus for managing a consumption right for each stage for a service including a plurality of stages or episodes. The right issuer includes the access condition, which allows an access to the Right Object (RO) for each stage, in the right object representing the consumption right for the stepped multimedia service and then transfers the right object to the device. When the stepped multimedia service is executed, the device obtains the access information satisfying the access condition corresponding to a corresponding stage from the right issuer or a service provider and then transfers the access information to the RO, allowing a user to access the RO and execute a service of the corresponding stage by using the RO.

摘要： 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.

摘要： Disclosed is a DRM Proxy Server Agent (DRM PSA), which converts a format of a DRM system into a format recognizable in a user terminal when the user terminal and a service provider do not use the same type of DRM system. The user terminal downloads the DRM PSA from the service provider and installs the DRM PSA in the user terminal. Through the download and installation of the DRM PSA, the user terminal can use various DRM systems provided by the service provider regardless of the type of DRM system installed in the user terminal.
