A universal non-proprietary digital radio system with
undistorted digital-quality sound and advanced radio features for the AM and
VHF bands, available to markets worldwide.
Digital Radio Mondiale (DRM) is an over-the-air transmission
system developed for the broadcasting bands below 240 MHz. Its modulation
configurations include "DRM30" for the AM bands and "DRM+"
for the VHF bands.
Digital Radio Mondiale targets markets worldwide. As a
universal non-proprietary digital radio system, DRM holds the promise of
revitalizing short-wave, medium-wave, and long-wave broadcasting while adding
broadcaster-controlled individual-station transmission options for local and regional
coverage in the VHF bands.
The quality of DRM audio in the AM bands is a dramatic
improvement over that of analog AM. Apart from providing clear, near-FM quality
sound, the robustness of the DRM signal can be chosen to match different
propagation conditions. In addition, the DRM system has the capacity to
integrate data and text.
DRM applications are expected to include fixed
and portable radios, car radios, and other mobile terminals such as cellular
The patent pool license for Digital Radio Mondiale offered
by Via Licensing has been adjusted in order to reflect updates of the DRM

The audio portion of the Digital Radio Mondiale
technical specification now mandates support for the xHE-AAC (Extended
High-Efficiency AAC) audio codec in addition to HE-AAC v2. Please see the
