DRM Press Release: DRM+ successfully trialled in Paris

DRM+ extends the DRM standard which is the open, universal, digital radio standard for broadcast bands, to frequencies up to 174MHz including the FM spectrum from 87.5MHz to 108 MHz. DRM+ offers a range of features and benefits for radio stations’ around the world and can lead to a cost-effective migration to digital. It was first successfully tested on the FM Band in Kaiserslautern, Germany last year, but this is the first time DRM+ has been used in Band 1.

 

DRM+ has distinct advantages over conventional FM, it needs lower transmission power for same coverage, opens up new audio possibilities like 5.1 surround sound, increases spectrum efficiency and offers electronic data services such as programme guide and supporting information.

 

David Blanc, SNRL (Syndicat National des Radios Libres) says: “Professor Dr Andreas Steil and his team (Mr. Schad and Mr. Köhler) from the University of Applied Sciences, Kaiserslautern, was able to put together a complete DRM+ broadcast system on Band 1 and agreed to test it in Paris. SNRL, which gathers over 300 local stations in France, has been trying to find a technical solution for the many stations which cannot join multiplexes for various reasons, including coverage area, cost and desire to remain in control of their broadcast operations. “

 

“DRM+ seems to be an excellent choice, offering over 100 kbps of usable bit rate, enabling CD audio quality, slideshow and other data to be broadcast from a simple privately-owned transmitter. We now recommend integrating DRM+ in all digital radio receivers, from 60 to 108 Mhz.”, he added.

 

This test was performed by the help of University of Applied Sciences, Kaiserslautern and Fraunhofer IIS, Erlangen.

 

Ruxandra Obreja, Chairman, DRM Consortium says: “Through this trial in France, we have yet another proof that the DRM standard can offer a most versatile, economical range of options for big and small operators for the benefit of audiences that want good quality radio. We hope that the trial in France will be positively noted and actioned by the French radio authorities. It is an excellent extra step that will preface the expected all- band extension of the DRM global standard.”  


 

About DRM and DRM+

 

DRM+ uses the same audio coding, data services, multiplexing and signaling schemes as the established part of the DRM standard for short, medium and long wave up to 30 MHz, but operates in higher frequencies between 30 and 174 MHz (including the broadcasting bands Band I and Band II). The DRM Consortium has completed the technical development of DRM+. The technology enhancement to the DRM system specification is currently in the ETSI standardization process. Digital Radio MondialeTM (DRM) is the digital broadcasting system for the broadcasting bands below 30MHz (long, medium and short wave). DRM has near-FM sound quality plus the ease-of-use that comes from digital transmissions, combined with long range and low power consumption.
