EtherWaves Releases DAB+/DAB Software Update

Sep 18, 2012 2:51 PM, By Doug Irwin, CPBE DRB

Tel-Aviv, Israel - Sep 18, 2012 - EtherWaves released a new multicore Linux version of its ClearSignal software-based DAB/DAB+/DMB system to add support for the Transport Protocol Experts Group (TPEG) and other advanced decoding services. Use on DAB+ as a platform for these services is imminent. 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 buses 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 the 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 new ClearSignal version should immediately appeal to the manufacturers of European cars, following ITS Directive from the EC and with TPEG over DAB+ that recently received a huge boost from the German Public Broadcaster ARD and the German automobile club ADAC.

With the rapid introduction of powerful processors in smartphones and automotive head-units, EtherWaves is focused on reducing customers' system costs and financial risks involved in maintaining stocks of dedicated ASICs. Previous versions of ClearSignal have been used by Tier 1 automotive 'infotainment makers', deployed in high-end German and Italian automotive cars and used by innovative SoC (system on a chip) manufacturers.
