This is a multi-part deliverable identifiable by the same main number and a common part of the title. This set of
16、partial deliverables (parts and sub-parts handled and published independently but treated in a coordinated form) build a whole deliverable handling the subject identified by the common part of the title. The common part of the title is Media Content Distribution framework. Each part and sub-part of
17、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 a specific number attached to the common main number of the deliverable will also be assigned. The pres
18、ent document, the only one providing a collection of the concerns and needs expressed by Content Providers, is part 2 of the multi-part deliverable covering the Media Content Distribution framework, as identified in part 1 of this multi-part deliverable. For a rational maintenance and easy usage of
19、the complete set of the documents, only part 1 of the set of the documents, will maintain an updated list of the documents in the series, all the other documents should refer to part 1, working therefore as the central point of the series. Introduction In the context of MCD work, as explained in par
20、t 1 of this multi-part deliverable, the collection of Content Providers views and needs were early identified as a major step to proceed to the necessary analysis in this sector. Content Providers have clear ideas on the consumerss needs, they understand the environment of MCD and start to take adva
21、ntage of the different MCD means offered by the convergence of technologies and systems. Their opinion is therefore a central tool for the identification of MCD requirements and the specification of a roadmap for the standardization work to be developed. In addition commercial solutions developed by
22、 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, whilst at the other end, customers buy-in
23、remains well below expectations. If some particular standards are centred in the Contents Providers needs and views, reference should be made to them. E.g. some discussions on H4TV, a standard for the authoring and interoperable delivery over broadcast and on line media of interactive services autho
24、red in a web technologies-based format, should be included since this standard is very much Content Providers needs oriented. ETSI ETSI TR 102 688-2 V1.1.1 (2010-03)5Most important requests for MCD platforms and systems, like interoperability, Quality of Service (QoS) and Quality of Experience (QoE)
25、, Security and content owner rights, and many others are reflected in the structure of the present document in order to facilitate its usage and to help further discussions for the establishment of MCD requirements and roadmap. The conclusions achieved for each one of the areas of the identified nee
26、ds may result later in new parts of this multi-part deliverable, where each one of the most relevant subjects will be handled in depth, beneficiating from conclusions obtained in other parts of this multi-part deliverable. The work TC-MCD is undertaking intends to be based on a neutral, objective, i
27、ndependent approach in order to prevent cooperation difficulties with relevant players and, most of all, to ensure that no biaising effect is introduced in the market own choices. No preference should be demonstrated for any solution or system on the market, but the objective advantages of some syst
28、ems when satisfying some particular requirements should be noted. ETSI ETSI TR 102 688-2 V1.1.1 (2010-03)61 Scope The present document belongs to a set of deliverables proceeding to the widest possible coordinated study on the media content distribution (MCD) matters with the primarily goal of ident
29、ifying standardization needs not covered or not correctly covered at the present stage of development. This set of documents will cover at least the activities and areas better specified in part 1 of this set of documents. The present document is part 2 of the set of documents and collects, lists an
30、d discusses the Content Providers needs and opinions falling within the wide scope of this set of documents. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
