Regardless of whether you want to manufacture transmission equipment or design a receiver: Fraunhofer IIS has the technologies you need.

Fraunhofer technologies underpin not only the basic digital radio standard, from audio compression to data services and signal rendering, but also form an integral part of many products that enabled the successful introduction of digital radio.

Many of the radio encoders used by broadcasters and made by different manufacturers are based on Fraunhofer’s ContentServer Technology. These highly compact solutions combine real-time audio encoding with the complete management of all standardized data services, and the production of the final digital broadcast signal.

On the receiving end, Fraunhofer technologies offer radio manufacturers a wide range of options. These extend from software defined radio solutions for DAB and DRM reception, to decoder components for audio and additional services such as Journaline® and EWF (Emergency Warning Functionality), through to complete PC-based radio solutions.

Digital radio offers advantages to radio listeners, manufacturers and broadcasters:

More than just radio

With additional multimedia features, digital radio has become much more than just an acoustic medium. It adds visual experiences and opens up new ways for traffic information services and other services.

More efficiency

Radio stations benefit from efficient program transmission: reduced energy consumption for transmission combined with increased capacity for additional programs cuts down operational costs.


With our ready-to-run software, manufacturers can easily enhance their existing radio platforms with DAB and DRM functionality.

More program variety

Thanks to advanced digital processing, significantly more programs than with analog technology can be broadcast over the available frequencies. This creates free space for new stations and new listening experiences.

Excellent sound quality

Digital radio listeners benefit from clear reception and high quality sound – anywhere and anytime.
