4. GENERAL DESCRIPTION
4.8.3.
RDS Board
Introduction
For several years now, within the field of radio broadcasting, the importance of
transmitting data packets of various types, over and above the radio signal, has been
recognised as crucial to improving the quality and reliability of the services offered, let
alone implementing new ones.
This need was acknowledged at international level and a study group was given a
mandate to identify the various needs and define a transmission standard which is suitable
for the sector.
The group created the RADIO DATA SYSTEM (RDS) which is now the most diffuse
system of data transmission in the radiophonic sector.
The optional RDS board fits in the slot indicated on page 7 of this technical
manual.
The ETG250 (ETG300)’s optional RDS board allows a data channel to be tran-
smitted alongside the radiophonic signal (mono or stereo), in conformity with the “Speci-
fication of the radio data system (RDS)” document, published by the European Committe
for Electrotechnical Standardization (CENELEC) Ref. NO. EN50067:1990.
RDS system
The RADIO-DATA-SYSTEM (RDS) has been specified for the transmission of infor-
mation within mono/stereophonic programmes in the VHF/MF (87.5-108MHz) band,
thus satisfying the requirements for transmission of additional data in radiophonic pro-
grammes.
> Compatibility with actual mono/stereophonic programmes
> Absence of intereference between adjacent channels
> Compatibility with other existing systems of identification
