In March 2004, the European Commission established the High Level Group (HLG) on Digital Rights Management to address and discuss the obstacles to the implementation of DRM. The HLG comprises mainly ICT companies and industry associations. The Group agreed to focus on five issues: * Interoperability requirements * Acceptance and trust by users * Migration to legitimate services * Impact of DRM on existing rights management approaches, in particular levies, and * Assessment of some DRM applications.
