SIST EN 300 751 V1.2.1:2003

Radio broadcasting systems; DAta Radio Channel (DARC); System for wireless infotainment forwarding and teledistribution

Revision of ETS 300 751 (SWIFT) renamed to DAta Radio Channel (DARC). There remains some bugs and unclear example. And a few ToBeDefined has also been defined during the working of my Working Group, assigned its mission by the DARC Forum. We have also found some recommendations for related interfaces that could be of interest to attach as annexes.

Foreword
This European Standard (Telecommunications series) has been produced by Joint Technical Committee (JTC)
Broadcast of the European Broadcasting Union (EBU), Comité Européen 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 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 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 broadcast
