Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the E
21、uropean Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and rela
22、ted 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 organizations whose work includes the
23、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 GRAND SACONNEX (Geneva) Switzerland
24、 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 is to establish the framework for the introduction of MPEG-2 based digital television services. Now compri
25、sing 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 the broadcast industry. Introduction The present document describes the usage of PSI/SI information in IPDC
26、 in DVB-H System. The document intentionally constrains PSI/SI to simplify requirements for equipments developed for IPDC in DVB-H 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. T
27、he reader is assumed being familiar with MPEG/DVB defined PSI/SI information. The aim of the present document is to 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 vendo
28、r should understand how the information is available. The contents of the present document are normative for IPDC DVB-H Networks and IPDC DVB-H Receivers, unless otherwise stated. ETSI ETSI TS 102 470 V1.1.1 (2006-04) 6 1 Scope The focus of the present document is on PSI/SI tables and descriptors us
29、ed in IPDC in DVB-H Systems. Tables and descriptors are introduced, and their usage is described. 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
30、available on the IPDC DVB-H Bearer. The scope of the present document is to support coherent and interoperable signalling on data link layer on all IPDC DVB-H Networks 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present

37、 optics, terrestrial channel of one emitting point. DVB network: collection of MPEG-2 Transport Streams, each carrying a multiplex, and transmitted on a single delivery system NOTE: DVB network is identified by network_id. DVB service: collection of associated Elementary Streams NOTE: DVB service is
38、 identified by program_number (in PSI), or service_id (in SI). DVB signal: radio signal carrying a Transport Stream of a DVB network DVB-H: transmission system targeted to provide IP-based services to handheld terminals over terrestrial radio channels, as defined in EN 302 304 8. elementary stream:
