Introduction
Alongside well established TV delivery solutions, new services and applications offering content via a variety of
technical platforms over managed and unmanaged networks have emerged in a rapidly evolving environment. This has
led to a widely fragmented market in terms of proprietary and standardized elements of the platforms and the CA/DRM
solutions in use.
The variety of solutions, involving standardized and proprietary elements, presents obvious challenges to content
providers wanting to distribute their content to broad communities of end-users while a fragmented world market is an
obstacle for manufacturers of consumer equipment wanting to maximize economy of scale due to the need to adapt for
different technical platforms and CA/DRM systems. Last but not least, consumers may appear to lack the utmost
flexibility in choosing services and available content due to the service providers use of different delivery platforms and
CA/DRM systems.
The present document examines the underlying reasons for the variety of delivery platforms focussing on standards and
solutions in the market for CA/DRM interoperability and considers whether new standardization initiatives will help to
reduce market fragmentation and improve interoperability in the solutions used for distribution and consumption of
multimedia content.

1 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.
