Radio Revolutionised by Dolby Digital 5.1 Sound

Sep 12, 2003
Amsterdam, 12 September 2003--German public broadcasters Bayerischer Rundfunk (BR) and Westdeutscher Rundfunk (WDR) have demonstrated the world's first Dolby® Digital 5.1 surround sound radio services to the international broadcast industry at the IBC 2003 Convention in Amsterdam. The demonstration follows the overwhelming response to test transmissions during the recent IFAconsumer electronics exhibition in Berlin.

The Dolby Digital 5.1 surround radio transmissions make use of the DVB receivers that consumers are already using for digital television.

"With Dolby Digital, our original radio productions such as radio plays and concerts can be conveyed much more vividly and dramatically than with the conventional stereo system. This is a natural step for us, as everybody equipped to receive German digital TV channels in Dolby Digital can already receive the enhanced radio services," commented Martin Wöhr, Head of Studio Production and Operations at BR Radio.

Both BR and WDR have been gaining experience in producing surround sound audio over the last few years, particularly with music and drama programming.

"The success of the transmissions at IFA2003 convinced us to continue the tests with selfproduced multichannel radio drama and music productions," stated Horst Müller, Head of Radio Technology at WDR. Dolby Digital 5.1-channel programming already scheduled for broadcast during the technical test phase includes a regular concert series from BR and several drama productions from WDR. The transmissions can be received via the Astra satellite by any listener with one of over 40 models of Dolby Digital-compatible DVB receiver. The test service can be found on Transponder 111 (Astra 1G, 12603.75 MHz, H, 22.000, 5/6).
