Foreword This European Standard (EN) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation
25、 ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE 1: 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 b
26、ody 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 co-ordination of its members activities in the technical, lega
27、l, 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.

28、t 147 was established in 1987, with funding from the European Commission, to 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, ETSI ETS 300 401 i.1, for DAB (see note 2) which now has worldwide
29、 acceptance. NOTE 2: DAB is a registered trademark owned by one of the Eureka Project 147 partners. The DAB family of standards is supported by WorldDAB, an organization with members drawn from broadcasting organizations and telecommunication providers together with companies from the professional a
30、nd consumer electronics industry. With respect to the previous version of ETSI EN 300 401 published in June 2006, the present document contains several refinements to the DAB system. These refinements were performed and agreed by the WorldDAB Forum and include the following areas: additional rules a
31、nd guidance on use of certain features; addition of MCI and SI FIGs to enhance receiver behaviour; removal of some obsolete service information features; removal of transmission modes II, III and IV; DAB audio (MPEG layer II) details moved to a separate ETSI document.

34、 “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI EN 300 401 V2.1.1 (2017-01) 9 1 Scope The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed for delivery of high-quality digital audi
35、o and video programmes and data services for mobile, portable and fixed reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands as well as for distribution through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terres
36、trial transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB system meets the required sharing criteria with other radiocommunication services. The present document defines the DAB transmission signal. It includes the coding algorithms for mu
37、ltiplexing of audio and video programmes and data services, channel coding and modulation. Provision is also made for transmission of additional data services which may be programme related or not, within the limit of the total system capacity. The present document provides information on the system
38、 configuration which includes information about the ensembles, services, service components and linking of them. 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. 2 Reference
