Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of th
27、e European Broadcasting Union (EBU), Comit Europen de Normalisation 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
28、 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 television receivers. The EBU is a professional association of broadcasting organizations whose work includes
29、 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 area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switze

Their work resulted in the publication of European Standard,
31、 ETSI EN 300 401 1, for DAB (see note 2) which now has worldwide 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 telecommuni
32、cation providers together with companies from the professional and consumer electronics industry. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 o
33、f the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI TS 103 461 V1.1.1 (2017-08)6 1 Scope The present document describes the minimum requirements for digital radios, both d
34、omestic and in-vehicle, and the necessary test methods that lead to compliance with the requirements. It may be used as the technical basis for a Digital Radio Certification Mark scheme. A Digital Radio Certification Mark is designed to be used on product packaging and provides an easily recognized
35、mark to correspond to public information campaigns on the necessary requirements for consumers to make a switch to digital radio. Manufacturers are, of course, free to include additional features or increased performance compared to the minimum requirements specified in the present document. 2 Refer
