ETS 300 429: December 1994 Foreword
This European Telecommunication Standard (ETS) has been produced under the authority of the Joint Technical Committee (JTC) of the European Broadcasting Union (EBU) and the European Telecommunications Standards Institute (ETSI).
回到NOTE:The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of ETS in the specific field of radio, television and data broadcasting.
The EBU is a professional association of broadcasting organisations who 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

This ETS describes framing structure, channel coding and modulation for digital multi-programme television by cable, it has been prepared by the Project Team PT-55V. The work of the Project Team was bad on the studies carried out by the European Digital Video Broadcasting (DVB) Project under the auspices of Ad hoc Group for Digital Television by Cable (DTVC). This joint group of industry, cable operators and broadcasters provided the necessary information on all relevant matters to the Project Team, e DTVB 1190/DTVC 38 (bibliography).
This ETS is Part of the complete "Multivision system" (this name is currently under review) which covers the baband image coding, baband sound coding, baband data rvice coding, multiplexing, channel coding and modulation for satellite rvices, channel coding and modulation for cable and Satellite Master Antenna Television (SMATV) distribution and common scrambling system.
