Foreword

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

23、tablished 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 televisio

24、n 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 broadcasting are

European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 Founded in September 1993, the DVB Project is a market-led consortium of public and private sector organizations in the television industry. Its aim i

26、s to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and th

27、e broadcast industry. The present document is part 1 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“. Introduct

28、ion The present document describes the usage of PSI/SI information in IPDC in DVB-H System. The document intentionally constrains PSI/SI to simplify requirements for equipments developed for IPDC in DVB-H Systems. TS 102 470-2 i.3 is a corresponding document describing usage of PSI/SI information in

29、 IPDC in DVB-SH systems. Intended readers of the present document are those implementing or operating IPDC in DVB-H Networks as well as those implementing receivers for such networks. The reader is assumed being familiar with MPEG/DVB defined PSI/SI information. The aim of the present document is to

30、 define the way PSI/SI information is used in IPDC in DVB-H Systems. An operator of an IPDC in DVB-H Network should understand what information should be available, and a receiver vendor should understand how the information is available. ETSI ETSI TS 102 470-1 V1.2.1 (2009-03)6The contents of the p

31、resent document are normative for IPDC DVB-H Networks and IPDC DVB-H Receivers, unless otherwise stated. ETSI ETSI TS 102 470-1 V1.2.1 (2009-03)71 Scope The present document describes PSI/SI tables and descriptors usage in DVB-H system. Tables and descriptors are introduced, and their usage is descr

32、ibed. The present document defines the set of PSI/SI data an IPDC DVB-H Receiver may expect to be available on an IPDC DVB-H Bearer (data transmission baseband) and the IPDC DVB-H Network is expected to make available on the IPDC DVB-H Bearer. The scope of the present document is to support coherent

33、 and interoperable signalling on data link layer on all IPDC DVB-H Networks 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
