Abstract

This study proposes DRM architecture for VOD streaming services in a mobile environment. The proposed system architecture consists of DRM Client Manager, in which core components for client services are independently constructed to be used in a mobile environment, and DRM server, which provides DRM services. DRM Client Manager independently exists in the client to maximize efficiency and processing capacity in such a mobile environment, and consists of user interface, license management and player. DRM server consists of streaming server for VOD streaming, contents server, license server, and packager. The proposed system has an architecture suitable for a mobile environment that is difficult to process in the existing DRM architecture and considers the process of super-distribution through an independent manager in the client.
