SIST ETS 300 801 E1:2003

Digital Video Broadcasting (DVB); Interaction channel through Public Switched Telecommunications Network (PSTN)/ Integrated Services Digital Networks (ISDN)

This ETS is the baseline specification for the provision of return channel based on PSTN and ISDN to DVB Systems. It is noted that the DVB does not intend to specify a return channel solution associated to each broadcast system because the interoperability of different delivery media to transport the return channel is desirable. Therefore the PSTN/ISDN solutions for the return channel apply to satellite, cable, SMATV, terrestrial, MMDS or any future DVB broadcasting system. The solutions here provided for return channel through PSTN/ISDN are a part of a wider set of alternatives to implement interactive services for DVB broadcasting systems.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Joint Technical Committee
(JTC) of the European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique
(CENELEC) and the European Telecommunications Standards Institute (ETSI).
NOTE: The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of standards in
the specific field of broadcasting and related fields. Since 1995 the JTC 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 broadcasting area; its headquarters is in Geneva *.

Digital Video Broadcasting (DVB) Project
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 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.

1 Scope
This European Telecommunication Standard (ETS) is the baseline specification for the provision of Return
Channel (RC) based on PSTN and ISDN to Digital Video Broadcasting (DVB) systems.
It is not intended to specify a RC solution associated to each broadcast system because the
inter-operability of different delivery media to transport the RC is desirable. Therefore the PSTN/ISDN
solutions for the RC apply to satellite, cable, SMATV, terrestrial, MMDS or any future DVB system.
The solutions here provided for RC through PSTN/ISDN are a part of a wider set of alternatives to
implement interactive services for DVB systems.
