Re: [DX] RDS systeemi täytti 25 v
Tässäpä taas hyvä jutunjuuri Radiomaailmaan. Kuka muuten kuuli
ensimmäiset RDS-asemat Suomessa?

RDS celebrates 25th birthday
13 March 2009
It is now 25 years ago (March 1984) that the EBU published the original
RDS (Radio Data System) specification, also known as 'EBU Tech 3244'.
The development of the system was started in 1975 by the EBU Technical
Committee. Since then RDS has become enormously succesful worldwide.
History
Credits for the basic concept behind RDS go to German organisations
Bosch/Blaupunkt and the IRT. It is their analogue 'ARI' (Autofahrer
Rundfunk Information) system that triggered the development of digital
'nephew' RDS, managed by Ernst Schwarz (Swiss PTT) and Dietmar Kopitz
(EBU). After publication in 1984 of the RDS spec, in 1987 the first RDS
car radio was marketed by Volvo. A year later regular RDS services
started in Austria, Belgium, Denmark, Germany, Italy and the United
Kingdom. For radio users RDS may be known most of all for the Programme
Service name on their radios (RDS-PS) and Traffic Announcement (RDS-TA
and RDS-TP) switching.
Visionary work
The production of hundreds of millions of RDS equipped car radios is a
testimonial to its visionary development process. A small test at the
International Motorshow that is currently being held in Geneva, revealed
RDS is very well known in the industry and is still used as a selling
argument in radio specifications. In recent years RDS technology has
even found its way into mobile phones. Despite no expectation of such a
requirement for the original developers this required no change to the
specifications!
RDS-TMC
One element of RDS particularly interesting to modern navigational
equipment is RDS-TMC, the traffic information system. Recommended by the
European Commission in 1994 for the 'Trans-European Road Network', this
system is used in many European countries. However, with the renewed
interest in digital radio, RDS-TMC could become (gradually) replaced by
its younger 'cousin', TPEG (Transport Protocol Experts Group). The new
WorldDMB/EBU Digital Radio Profiles already mention both TMC and TPEG as
technologies to be used with digital radio.
Whatever the future will bring exactly, one thing is for sure: thanks to
the dedicated passion of many great engineers at EBU Members and
equipment manufacturers, RDS became the success it still is. Congratulations
