Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Eu
25、ropen 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 related fields. Since 1995 the JTC Broadcast
26、 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 co-ordination of its members activities
27、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.

28、4 81 The Eureka Project 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 EN 300 401 1, for DAB (see note 2) whic
29、h 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 World DMB, an organization with members drawn from broadcasting organizations and telecommunication providers together with companies fro
30、m the professional and consumer electronics industry. The RadioDNS Project was established in 2010 to standardize the combination of broadcast radio systems with additional applications, content and meta-data delivered over fixed or mobile IP networks. The project produced a specification using DNS
31、to locate the broadcasters Internet domain which is in use worldwide, and now standardized as ETSI TS 103 270 6. RadioDNS operates the authoritative name servers for the radiodns.org domain, and has members drawn from broadcasting organizations, manufacturers and service providers. NOTE 3: “RadioDNS

In respect to previous versions of the present document, hybrid radio provisions have been added to allow a seamless experience for users when consuming radio services delivered by digital radio broadcasting system
35、s (DAB, DRM) or IP or a combination of both. The use of the present document allows content to be created once by the service provider for delivery by both mechanisms and allows manufacturers to implement devices with many common elements. The application can be delivered using broadcast or IP, or a
36、 combination of the two. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
