Scalable DRM system for media portability

Abstract

We present a new digital rights management (DRM) system for media portability using dynamic multimedia adaptation. For a user to share multimedia resources over home network, several DRM technologies based on the domain have been introduced. Domain-based approaches enable users to access contents on multiple devices within the same domain. However, most of current DRM systems were only designed for a homogeneous environment where common AV profiles are supported. It is a challenge to share the domain contents between domain members with diverse capabilities while ensuring the protection of the intellectual property rights for the legally obtained contents. In this paper, we propose an architecture that enables DRM contents to be securely shared between various home devices in a seamless manner. © Springer-Verlag Berlin Heidelberg 2007.
