Foreword This Technical Report (TR) has been produced by Joint Technical Committ
29、ee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). The work of the JTC was based on the studies carried out by the European DVB Project under the auspices of the Ad Hoc
30、 Group on DVB-S2 of the DVB Technical Module. This joint group of industry, operators and broadcasters provided the necessary information on all relevant technical matters (see clause 2). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specifi
31、c 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 association of broadcasting organi
32、zations 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. European Broadcasting Union CH-1218 GRA

34、tandards 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 transmission through interfacing, conditi
35、onal access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardization, interoperability and future proof specifications. The present document is part 1 of a multi-part deliverable covering Digital Video Broadcasting (DVB); Implementat
36、ion guidelines for the second generation system for Broadcasting, Interactive Services, News Gathering and other broadband satellite applications, as identified below: Part 1: “DVB-S2“; Part 2: “S2 Extensions (DVB-S2X)“. Modal verbs terminology In the present document “shall“, “shall not“, “should“,
37、 “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation.

38、TSI TR 102 376-1 V1.2.1 (2015-11)7 1 Scope The present document is part 1 of a multipart deliverable and gives an overview of the technical and operational issues relevant to the system specified in ETSI EN 302 307-1 i.2, including service quality and link availability evaluation for typical DSNG an
39、d fixed contribution links, with the purpose to facilitate its interpretation. Correspondingly, ETSI TR 102 376-2 i.45 considers technical and operational issues relevant to the system specified in ETSI EN 302 307-2 i.44, but it can be applied also to DVB-S2, when enhanced S2 receivers and channel m
40、odels are implemented. 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.
