scope:

The present document about "Mechanisms addressing interoperability of multimedia service and content distribution and consumption with respect to CA/DRM solutions" gives an overview and provides guidance on several CA/DRM subjects, presents related activities in standardization bodies and discusses implementation issues. Special attention is paid to existing solutions already introduced to the market with regard to interoperability as well as to emerging software-based solutions, all operated under a trusted environment.

Analysis of solutions for interoperable multimedia content distribution and consumption with respect to CA/DRM, suitable for Multimedia platforms (broadcast, broadband or hybrid) and to the content/services delivered over them is the main focus of the present document, addressing:

• A review of the status of existing and emerging standards together with other attempts to produce interoperable and interchangeable CA/DRM solutions suitable for multimedia consumption across multiple networks and platforms.
• A presentation of the practical framework required for implementation and operation of a CA/DRM system.
• An analysis of the interoperability available using current solutions and lessons from all the attempts reviewed.
• Emerging market needs.
• Concepts for market implementation including business roles, liability and trust.
• Regulatory and legal issues.

The present document covers all aspects of interoperability involving standardized elements concerning Conditional Access (CA) and Digital Rights Management (DRM) solutions associated with content distribution and consumption across various technical platforms for conventional Broadcast TV (DVB-C/C2, -S/S2, -T/T2) as well as for Broadband TV (including IPTV, WEB-TV) and Mobile TV.
