In-vehicle infotainment systems have evolved from traditional radios/CD players into much more flexible platforms. The rising popularity of digital music, streaming services, internet radio, and Digital Radio has seen many auto manufacturers shift focus to connected services, smartphones, and multi-tuner designs.
Consumers want to use smartphones connected to the car by Bluetooth®, to play music or other content that either lives on their devices or is delivered over the internet, which is driving demand for near-CD/radio broadcast-quality stereo wireless audio.
CSR’s all-in-one silicon-software solutions for car radio significantly reduce BoM and engineering costs for auto OEM’s, integrating the four essential ingredients of the typical auto infotainment head unit: scalable multi-tuner radio, dual-mode Bluetooth 4.0 wireless connectivity, wideband speech (HD voice) with noise and echo cancellation, and on-chip A2DP stream decoding.
CSR’s aptX® is supported in most market leading smartphones and most of all Android devices shipping today. This Bluetooth codec is capable of offering high fidelity audio guaranteed through a comprehensive interoperability program (for all devices supporting aptX) and is set to become the standard means of delivering stereo audio to a head unit.
