HD Radio

One Core Does All World Digital Radio Standards

Designers of digital radio systems can use one processor core - Tensilica's HiFi 2 Audio DSP - to run all of the decoders required throughout the world for digital radio, enabling a universal worldwide digital radio receiver. Tensilica's HiFi2 Audio DSP supports all of the terrestrial and satellite standards: DAB, DAB+, HD Radio, DRM, and XM Radio.

Popular Worlwide Digital Radio Standards

The challenge with Digital Radio is that different audio standards are popular in different countries. Making one device that works in all is very important to get economies of scale. Just look at some of the standards in the geographies:

Why Digital Radio?

The big challenge is: How can we get more stations and better sound quality in the existing AM/FM radio bands? Digital radio answers this by providing much better sound quality, virtually no interference from other transmissions, and many more stations in the same bandwidth. Plus it's robust at lower transmission powers and provides datacasting services like iTunes song tagging and real-time traffic updates.
