Introduction Alongside well established TV delivery solutions, new services and applications offering content via a variety of technica
20、l 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 propriet
21、ary 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 tech
22、nical 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 var
23、iety 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 c
24、ontent. ETSI ETSI TR 101 532 V1.1.2 (2015-03) 61 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 rela
25、ted 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 soluti
26、ons 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 a
27、nd 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 anal
28、ysis 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
29、 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
30、, WEB-TV) and Mobile TV. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
