NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the dra

16、fting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional a

17、ssociation of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva. Europe

19、s committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmis

20、sion through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. The present document is part 1 of a multi-part deliverable covering the DVB Inte

21、ractive Satellite System specification, as identified below: TS 101 545-1: “Overview and System Level specification“; EN 301 545-2: “Lower Layers for Satellite standard“; TS 101 545-3: “Higher Layers Satellite Specification“; TR 101 545-4: “Guidelines for Implementation and Use of EN 301 545-2“; TR

22、101 545-5: “Guidelines for the Implementation and Use of TS 101 545-3“. ETSI ETSI TS 101 545-1 V1.2.1 (2014-04)5Introduction EN 301 790 1 defines the first generation of DVB-RCS which is a system providing an interaction channel for satellite distribution systems. Together with its guidelines (TR 10

23、1 790 i.1) the present document describes how such system can be built on the physical and MAC layers to provide an efficient way of turning a satellite broadcast TV into a full VSAT solution capable of transporting IP traffic in a satellite-only system. Since the original definition of DVB-RCS syst

24、ems, several versions of the standard were issued, describing the requirements for the implementation of a system providing an interaction channel for satellite distribution systems. The sum of these specifications allowed to adapt the DVB-RCS systems to different market segments from small to large

25、 networks and from fixed to mobile terminals but it appears that the evolutions of the physical layer techniques and the stabilisation of IP standards now deserves deeper changes which can only be implemented in a consistent way via the definition of a second generation system. The requirements in t

26、he present document have been introduced in order to provide the best possible interoperability between terminals and hubs, thus defining not only the lower layers of the system (up to layer 2) but also network functions as well as management and control capabilities. As these requirements combined

27、together may end up in a very complex terminal design, the present document also describes subsets of capabilities known as profiles that can be used together to address a given market segment. ETSI ETSI TS 101 545-1 V1.2.1 (2014-04)61 Scope The present document establishes the system specifications

28、 for the 2ndGeneration Interactive DVB Satellite System (DVB-RCS2) and represents the first part of the multi-part specification of that system. It also gives links to the adequate sections into the detailed specification documents and explains how the features should be combined together to make a

29、terminal compliant with different subsets of specifications mentioned here as profiles. General terms and definitions are given in the present document which can be found also in the other parts of the DVB-RCS2 multi-part specification. 2 References References are either specific (identified by date
