Foreword This European Standard (Telecommunications series) has been produced by Joint Technical Committee (JTC) B
35、roadcast of the European Broadcasting Union (EBU), Comit Europen 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 broa
36、dcasting 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 w
37、ork 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 broadcasting area; its headquarters is in Geneva. European Broadcasting Union CH-I218 GRAND SACONNEX (Ge

40、known by some other commercial slogans. The data required for these applications is transmitted by means of a data broadcasting protocol using the Vertical Blanking Interval (VBI) lines of a TV signal. It is also intended to coexist with other data-broadcasting applications running on affordable TV-
41、sets, VCRs, or multi-media PCs. The EPG enables a receiveddecoder to store a programme database (and, if available, a navigation database), which can help the viewer to find the programmes of his preference. 2 Re fe re nces The following documents contain provisions which, through reference in this
