Foreword This ETSI Standard (ES) has been produced by Joint Technical Committee (JTC) of the European Broadcasting Union (EBU), Comit E
32、uropen 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
33、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 i
34、n 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.

35、Founded in September 1993, the DVB Project is a market-led consortium of public and private sector organizations in the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25
36、 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry. ETSI 8 ETSI ES 200 800 V1.3.1 (2001-10) 1 Scope The present document is the baseline specification for the provision of the inte
37、raction channel for CATV networks. It is not intended to spec a return channel solution associated to each broadcast system because the inter-operability of different delivery media to transport the return channel is desirable. The solutions provided in the present document for interaction channel f
38、or CATV networks are a part of a wider set of alternatives to implement interactive services for Digital Video Broadcasting (DVB) systems. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
