Software Defined Radio – Hybridradio für FM/AM, DAB+, DRM und Internet

Modern hybrid radios switch automatically back and forth between analog VHF, digital DAB+, and Internet streaming. By always looking for the best way to receive a radio program, they allow passengers to enjoy uninterrupted listening as they travel. The technology also provides users with an easy way to enjoy their favorite local shows outside of the respective broadcast areas.

Hybrid infotainment-system functionality of this kind is possible through the integration of Fraunhofer software components. They provide radio platforms with the versatility to operate in various markets or vehicle categories and ensure uncompromising sound quality.  The software solution for hybrid car radios includes data decoders that deliver images, text messages, and other information in addition to the audio content. For that purpose Fraunhofer Institute for Integrated Circuits IIS provides a corresponding full-stack solution that incorporates everything from baseband decoding to audio playback and a web-based user interface.

This implementation enables parallel processing of multiple inputs in real time, as well as access to the corresponding components via low- and high-level interfaces (C++ and REST-API). In addition, the hybrid radio implementation includes a client for IP-based streaming.
