30、Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadca

31、st was established in 1990 to co-ordinate the drafting 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

32、television receivers. The EBU is a professional association 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 broadca

33、sting area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software develo

34、pers, regulatory bodies, content owners and others 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 cove

35、r all aspects of digital television from transmission 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 2

36、of a multi-part deliverable covering the Digital Video Broadcasting (DVB); IP Datacast: Program Specific Information (PSI)/Service Information (SI), as identified below: Part 1: “IP Datacast over DVB-H“; Part 2: “IP Datacast over DVB-SH“. Introduction The contents of the present document specify the

37、 use of PSI and SI tables and related descriptors in DVB-SH networks, and more generally of all signalling elements relevant to the usage of DVB-SH network (TPS, Signalling Field, SHIP). TS 102 470-1 8 is a corresponding document describing usage of PSI/SI information in IPDC in DVB-H systems. The p

38、resent document describes how the network infrastructure is required to generate the signalling. In some cases, the behaviour of the receiver is also specified. More general description of receiver behaviour and not-directly PSI/SI related signal generation is FFS in DVB-SH the implementation guidel

39、ine. ETSI ETSI TS 102 470-2 V1.2.1 (2011-09)7The use of PSI/SI tables and/or descriptors not mentioned within this clause is either not restricted for any particular network and specifying the use of such tables/descriptors is either outside of the scope of the present document, or can be applied fo

40、r both DVB-H and DVB-SH networks and therefore can be found in 8. Clause 4.1 provides some introduction to the PSI/SI in DVB-SH. Clause 4.2 specifies content regionalization concept within a “partially available TS“. Clause 4.3 specifies MPE usage. Clause 4.4 specifies the descriptors required and t

41、heir usage. Clause 4.5 specifies the PSI tables usage. Clause 4.6 specifies the SI tables usage. Clause 4.7 specifies the TPS and Signalling Field parameters and their usage. Clause 4.8 specifies the Update Notification Table usage. Clause 4.9 specifies the INT announcement usage. Clause 4.10 specif

42、ies SHIP usage. Clause 4.11 specifies the signalling field usage. ETSI ETSI TS 102 470-2 V1.2.1 (2011-09)81 Scope The present document provides focus on PSI/SI tables and descriptors used in DVB-SH Systems. Used tables and descriptors are introduced, and their usage is described. The present documen

43、t defines the set of PSI/SI data a DVB-SH Receiver may expect to be available on a DVB-SH bearer (data transmission baseband) and the DVB-SH Network is expected to make available on the DVB-SH Bearer. 2 References References are either specific (identified by date of publication and/or edition numbe

For non-specific references, the latest version of the reference document (including any amendments) applies.
