    摘要: An encryption key distribution method for service and content protection in a mobile broadcasting system, and a system for the same which includes generating, by a network, a first encryption key when the broadcast service is first provided; transmitting a generalized rights object message, which includes identification information for identifying the generated first encryption key, to the terminal; generating a second encryption key before the lifetime of the first encryption key expires; and transmitting the generalized rights object message, which includes identification information for identifying the generated second encryption key, to the terminal.

    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: A method is provided for controlling content playback by a terminal in a content delivery system. The method includes receiving streaming content from a service provider, the streaming content including zone information of each zone and an associated identifier of each zone for identifying a terminal's operation mode, determining the terminal's operation mode depending on the identifier, and controlling playback of the streaming content in a zone corresponding to the zone information according to the determined operation mode.

    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.
