Foreword This European Standard (Telecommunications series) 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 I

28、nstitute (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 related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is re

29、sponsible for the standardization of radio and 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 member

30、s in about 60 countries in the European broadcasting 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 Eureka Project 147 was established in 1987, with funding from the European Commission, to

31、develop a system for the broadcasting of audio and data to fixed, portable or mobile receivers. Their work resulted in the publication of European Standard, ETS 300 401 7, for DAB (see note) which now has worldwide acceptance. The members of the Eureka Project 147 are drawn from broadcasting organiz

32、ations and telecommunication providers together with companies from the professional and consumer electronics industry. NOTE: DAB is a registered trademark owned by one of the Eureka Project 147 partners. The present document on Digital Audio Broadcasting (DAB) is based on the overall system and ser

33、vice requirements adopted by the ITU-R Recommendation BS.774 1 and ITU-R Recommendation BO.789 2. The DAB system has been recommended by the ITU-R, as Digital System A, for terrestrial and satellite delivery. The audio coding algorithm used by the DAB system has been subject to the standardization p

34、rocess within the ISO/Moving Pictures Expert Group (MPEG), see ISO/IEC 11172-3 3 and ISO/IEC 13818-3 11. The layered ISO open system interconnect model ISO 7498-1 4 has been used to the extent possible, and interfacing to information technology equipment and communications networks has been taken in

35、to account where applicable. The present document defines the nature and content of the transmitted DAB signal with reference to the conceptual emission part. The emphasis is given to the normative elements. Informative elements are included only to the extent necessary to provide interpretative gui

36、dance to the DAB system users and equipment manufacturers. The DAB system is a novel sound broadcasting system intended to supersede the existing analogue amplitude and frequency modulation systems. It is a rugged, yet highly spectrum and power efficient sound and data broadcasting system. It has be

37、en designed for terrestrial and satellite as well as for hybrid and mixed delivery. The DAB system has been publicly demonstrated on a number of occasions during its development. It has been subject to extensive field tests and computer simulations in Europe and elsewhere. It is now in regular servi

38、ce in many European countries and throughout the world. In 1995, the European DAB Forum (EuroDab) was established to pursue the introduction of DAB services in a concerted manner world-wide, and it became the World DAB Forum (World DAB) in 1997. ETSI ETSI EN 300 401 V1.4.1 (2006-06) 9 With respect t

39、o the previous version of EN 300 401 published in May 2001, the present document contains several refinements to the Eureka 147 DAB system. These refinements were performed and agreed by the World DAB Forum and include the following areas: backward compatible changes to PAD to provide greater flexib

40、ility; addition of Forward Error Correction mechanisms for packet mode service components; addition of extended labels and character definition; removal of some obsolete service information features; conditional access details moved to a separate ETSI document.

42、.4.1 (2006-06) 101 Scope The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed for delivery of high-quality digital audio programme and data services for mobile, portable and fixed reception from terrestrial or satellite transmitters in the

43、 Very High Frequency (VHF)/Ultra High Frequency (UHF) frequency bands as well as for distribution through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terrestrial transmitter network planning, known as the Single Frequency Network (SFN) and the gap

44、-filling technique. The DAB system is suitable for satellite as well as hybrid/mixed terrestrial/satellite broadcasting, using a simple, nearly omni-directional receiving antenna. The DAB system meets the required sharing criteria with other radiocommunication services. The present document defines

45、the DAB transmission signal. It includes the coding algorithms for audio, multiplexing of audio programme and data services, channel coding and modulation. A limited range of supplementary services associated with programme services is defined. Provision is also made for transmission of additional d

46、ata services which may be programme related or not, within the limit of the total system capacity. The present document provides information on the system configuration which includes information about the ensembles, services, service components and linking of them. Provision is made for a compatibl

47、e cross-reference to existing Frequency Modulation (FM) services and Amplitude Modulation (AM) services. The present document describes the nominal characteristics of the emitted DAB signal. The aspects related to the receiver design are outside the scope of the present document. Hardware implementa

48、tion considerations are not covered. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specifi

49、c. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.
