CSR recently introduced to the market RadioPro, a WiFi Internet radio example design based on the company’s UniFi single-chip WiFi platform. RadioPro provides wireless streaming of Internet radio via WiFi, without the need for a PC and supports over 10,000 radio stations through a dedicated Internet radio portal. With a bill of materials (BOM) of less than $15, CSR’s RadioPro is the lowest cost Internet radio solution available today, according to the company, and comes with the added advantage of being software upgradeable. Radios using Figures published by RAJAR (Radio Joint Audience Research) show that almost a quarter of the UK population listened to the radio via the Internet in March 2007. However, as a relatively new entrant in the home entertainment arena, the initial cost for specific Internet radio products has so far come with a hefty price tag of no less than $200. CSR’s RadioPro will allow ODMs to bring Internet radio products to consumers at a fraction of the price that has been previously possible, taking advantage of this rising trend for Internet radio broadcasting.

RadioPro uses the company’s UniFi-1 chip to connect to a dedicated Internet radio portal through a WiFi access point. Once a station has been selected, RadioPro’s software ensures smooth, reliable and high quality streamed audio. CSR’s RadioPro also supports “over-the-air” software upgrades, allowing end users to update their products directly with new capabilities as they are made available.

Offering ODMs a quick route to market, RadioPro is available free of charge and features all the required hardware design information and software to stream live Internet radio stations. RadioPro’s flexible architecture allows full customization of the user interface and menus through a dedicated Software Development Kit (SDK). RadioPro is based on two low-power chips from CSR: UniFi, CSR’s single-chip WiFi platform and the Multimedia Application Processor (MAP), a highly integrated chip with a RISC processor, a DSP and a stereo codec. The low power design of RadioPro boasts up to 25 hours of active streaming time running on a 1500 mAH battery, enabling truly portable Internet radio products.

Tracy Hopkins, vice president of CSR’s Consumer Business Unit, commented, "The market for Internet radio products is forecasted to increase significantly within the next two years. With a $15 BOM, CSR’s RadioPro is a breakthrough design that provides ODMs with the ability to penetrate this market quickly, at lower risk and at low cost to the consumer.
