DAB+/ DAB software receiver for multicore Linux also supports TPEG

September 18, 2012 // By Julien Happich
EtherWaves announced the new multicore Linux version of its ClearSignal software based DAB/DAB+/DMB solution, to add support for the novel TPEG, DL+, EPM and other advanced decoding services.

With the imminent use on DAB+ as a platform for these services, the new version bring the fastest and most cost-effective path to sophisticated driving traffic data for digital radio manufacturers. And because of its multicore architecture, the new ClearSignal version provides enhanced processing power and resource utilization by taking advantage of the parallel processing found in the new media processors, with the result being reduced constraints of the ports and busses of today advanced DAB+/DMB receivers.

The first integration is available on a standard ARM core, such as those used in NVIDIA's Tegra, running a Linux-based OS, and using an off-the-shelf digital tuner from Maxim. Porting the same capability to different processors and tuners is a straightforward task, due to ClearSignal toolbox design approach. The new TPEG version implements all the Digital Radio broadcasting standards supported by ClearSignal - DAB, DAB+, T DMB and DRM, while exhibiting its proved and renown stability and high performance.


TPEG (Transport Protocol Experts Group) is one of technologies of the new generation of traffic and travel information services that are distributed via digital channels such as the internet, cell phones, and recently digital radio.

The DAB+/DMB stack has evolved in recent years beyond audio receiver as a data bearer for automotive data applications that integrate with other GPS, cell-phone and other infotainment sub-systems. Data applications have diverse requirements from the SDR platform and functions that used discrete hardware components, and now need to coexist as software components over the modern multi-core processors. The new ClearSignal multicore Linux version fits exactly this evolution of the automotive and SoC markets, with software rather than hardware-defined infotainment systems for a flexible, future proof, and user-friendly experience. The new ClearSignal multicore Linux version is available for licensing from EtherWaves, who also provides Digital Radio integration services for fast and cost effective implementation.
