DRM SERVICE PROVIDING METHOD, APPARATUS AND DRM SERVICE RECEIVING METHOD IN USER TERMINAL

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.
