Digital Radio Mondiale

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. It comprises optimized configurations for the AM bands below 30 MHz, providing large-area and international coverage at FM-like quality, and for the VHF bands including the FM band, for local/regional coverage with stereo up to Surround Sound services.  

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 phones.

Patent Licensing

The patent pool license for Digital Radio Mondiale offered by Via Licensing has been adjusted in order to reflect updates of the DRM technical specification, and to ease the deployment of multi-standard digital radio sets.

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 information provided here about the AAC patent licensing program administered by Via.

The DRM modem patents originally licensed through the DRM licensing program may be available for license by the patent owners directly.
