DRM – THE DIGITAL TECHNOLOGY FOR THE NEXT CENTURY

New: The new DRM-DMOD3 -Compact and Reliable

Despite new emerging technologies to distribute radio via web, cable and satellite, radio broadcasting is still undoubtedly the most efficient and convenient medium to receive radio, particularly for mobile applications.

The major advantage of LF, MF and HF broadcasting in the frequency range below 30 MHz is the huge coverage.
While all the other technologies need an extensive network or a high number of transmitters, AM broadcasting requires just a small number of transmitters, providing a program to particular target groups in a large geographical area.

Getting used to the high quality of VHF broadcasting required AM to be upgraded with a new technology providing the same standards of quality.

As DRM is the sole digital broadcasting system using the same frequency range and bandwidth as the existing analogue systems, broadcasters are offered major advantages as they can use the same frequencies and often the same transmitters as before.

DRM is characterised by transmitting one high quality program over a small AM frequency band. Consequently, DRM is also suitable for local broadcasters, who are interested in transmitting only a single program. Due to the limited availability of MF frequencies, local broadcasters alternatively can use the 11m HF-band from 25.67 to 26.1 MHz. Nationwide or international broadcasting will be possible on short wave using single frequency networks in all frequency ranges.

For the listener a new generation of receivers will selects channels by content, rather than broadcasting frequencies, thus automatically choosing the best available transmission channel. Several commercial DRM-receivers are available in the meantime. For further information about DRM-receivers, please visit the
DRM-website.

Digital Radio Mondiale (DRM) is the name of the international consortium, which defined the standards for digitalisation of AM broadcasting. DRM enables broadcasters to combine the advantage of VHF quality with the national and international coverage of AM broadcasting. TRANSRADIO, formerly TELEFUNKEN SenderSysteme Berlin, as a founding member of this consortium has tremendously influenced the standard with its experience and knowledge in broadcasting.

During 2005, DRM technology evolved past the testing phase as an increasing number of broadcasters initiated routine schedules of DRM transmissions. TRANSRADIO has established itself as the world’s leading DRM provider. Today, TRANSRADIO has the highest number of installed DRM transmitters in service.
