Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Media Content Distribution (MCD). This is a mu

21、lti-part deliverable identifiable by the same main number and a common part of the title. This set of partial deliverables (parts and sub-parts handled and published independently but treated in a coordinated form) builds a whole deliverable handling the subject identified by the common part of the

22、title. The common part of the title is Media Content Distribution framework. Each part and sub-part of the present set of deliverables covers a specific subject specified in the corresponding scope and referred to in the specific part of the title. To each part and sub-part of the whole deliverable

23、a specific number attached to the common main number of the deliverable will also be assigned. The present document is part 1 of a multi-part deliverable covering the Media Content Distribution framework, as identified below: Part 1: “Overview of interest areas“; Part 2: “Views and needs of content

24、providers“; Part 3: “Regulatory issues, social needs and policy matters“; Part 4: “Use cases and needs“; Part 5: “Standardization work“; Part 8: “Audience measurement“; Part 9: “Content Distribution Infrastructure (CDI)“. This list refers to the parts published or close to publication. The successiv

25、e editions of the present document will update the list. Clause 5 refers to all the possible parts of the set of documents building the TR 102 688 i.1 series as it is conceived by the date of publication of the present document (part 1 of the series); all the parts referred to in clause 5 and not ci

26、ted in this foreword may be cancelled or have the title or the scope changed according the evolution of the standardization work. For a rational maintenance and easy usage of the complete set of the documents, only the present document, i.e. part 1 of the set of the documents, will maintain an updat

27、ed list of the documents in the series, all the other documents should refer to the part 1. The present document works therefore as the central point of the series.

28、edia Content Distribution) Margot Dor (ETSI Secretariat - Director Strategic Projects) presented documents: ETSI/B69(08)58 - Creation of TC Media Content Distribution. ETSI/B69(08)42 rev.2 - Proposal for the creation of TC (MCD) Media Content Distribution. After some comments and overnight drafting

29、group resulted in ETSI/B69(08)42 rev.3 which was approved. D-B69/11 The Board approved the creation of a new Technical Committee for Media Content Distribution (MCD) and appointed Mr. Truls Langeggen (Telenor ASA) as convenor for the first meeting ETSI/B69(08)42 rev.3. Further to the discussion abov

30、e, the Secretariat was requested to provide a more detailed background information package. A-B69/3 ETSI Director-General (MDS) to provide a more detailed background information package on the issue related to Media Content Distribution ETSI/B69(08)42 rev.3. Background Today multimedia content is de

31、livered via broadcast networks, the Internet, IPTV, and mobile. Delivery methods include broadcast, unicast (e.g. 3G streaming services), multicast and peer-to-peer, but the experience is seldom homogeneous and seamless for the customers. Content delivery by its very nature also includes a number of

32、 restrictions and rules regarding rights. The worlds of broadcast and telecom traditionally have had their own standards track, based on different commercial requirements. Convergence between both worlds for content delivery results in a proliferation of technical options and specifications, which r

33、esult in a “standards maze“ and a lack of clear business models supported by an accepted technology. This does not serve business and customers interests, as broadcasters, telecom operators and internet players are offering what could be seen as similar services from a consumer perspective. In addit

34、ion commercial solutions developed by different market players do not interoperate across platforms. The crux of the matter is that at one end, content providers face the challenge to provide different content formats to the various distribution pipes, which in turn generates unbearable costs, whils

35、t at the other end, customers buy-in remains well below expectations. In general, there are a number of already deployed technologies addressing each of these different services in different markets and addressing various combinations. Arguably the most significant issue is that typically once a mar

36、ket has selected a technology, it most likely sticks to that choice. Although replacing one technology with another is possible in theory, in practice the barriers, often related to economical reasons, are substantial. Even where new functional requirements arise, existing solutions can in most case

37、s be extended to address them. This will normally be easier than replacing the technology with a newer one. This underlines the need to promote correct interoperation of equivalent services based on different technologies. Many in the industry point to the fact that without interoperability and cros

38、s-platform solutions for media distribution that really meet content providers and end users needs, market figures for digital media distribution may stay what they are today and investments may well exceed profits by far. In the early 2008 ETSI Secretariat initiated consultations with industry to a

39、ssess potential interest and support for an initiative aiming at addressing some of these technical barriers. Following a number of preliminary meetings with a large representation from the industry, particularly including content providers and broadcast related representatives, the Board approved t

40、he creation of a TC-MCD (Media Content Distribution) in the decision B69/11 and assigned the action B69/3 as stated above. ETSI ETSI TR 102 688-1 V1.1.1 (2010-03)7The present evolution of the communications market strongly influenced by convergence effects requires an extremely wide analysis to unde

41、rstand the specific needs in the communications sector. The growth of transmission rates supported by new technologies and offered by network operators determined convergence phenomena between the broadcasting and the telecommunications businesses. The increasing capabilities of new developed codexe

42、s, the digital transmission technologies together with fibre infrastructures and new radiotransmission technologies are facilitating convergence between mobile and fixed services. The popularity of internet, the penetration of PC and mobile phones and other smart terminals and systems accelerates th

43、e process of evolution determining an overall convergence in the ICT sector (telecom-broadcast-informatics, radio-fixed lines). This evolution forces infrastructures initially not intended for some services to be used to support them. What initially can be considered a problem appeared to be an addi

44、tional stimulus on the market to overcome the identified difficulties and the result is that e.g. VoIP initial tentatives quickly took a relevant place on the market and the recent evolution on IPTV and other IP based transmission systems are offering better performances and more functionalities at

45、a surprising evolution rate. To support this evolution and enhance the industry performance in this context the standardization has a central role and studies like the present one can bring together market players around the best solutions in order to deliver products and services to consumers with

46、shortest possible delays and highest performance at reasonable prices. Risks and opportunities Although classical Broadcast, IPTV, WebTV and MobileTV systems are operated independently from each other, many digital TV components are shared, e.g. Content Providers infrastructure, some parts of public

47、 Networks, e.g. Internet, CDIs (independent or operator), advertising insertion devices (SCTE), home devices and gateways (UPnP/DLNA), terminals and probably many others. Excessive fragmentation and non-interoperability of solutions for content distribution across platforms may: Generate prohibitive

Engender misgivings at both end of the line, i.e. for content providers (e.g. too many inter

There are already activities relating to media distribution taking place in and outside ETSI. Particular care should be taken not to duplicate work or overlap the scope of existing standards making bodies and organizations. In this context the set of documents will be essentially informative and will reach the detail necessary to achieve the purposes of TC MCD building strong cooperation relationships with the most relevant standard
