Digital radio receiver is seen as the future development trend since aside from receiving digital broadcast, it can receive image and text attachment information. However, the challenge lies in the restrictions set by multi-standards and frequencies.

As a response, Texas Instruments and Philips Semiconductor showcased their respective digital radio solutions at the 11th Annual International IC-China Conference & Exhibition (IIC-China), which are both based on compulsory HD Radio standard.

Philips' offering is based on its SAF7730 software radio DSP, which combines five DSP cores into a single chip and the signal processing is conducted completely using software. According to the company, this solution delivers high speed receiving and audio processing capability up to 650MIPS. It also incorporates PACS function and promises excellent audio receiving effect.

YongHong Hua, senior engineer at HD Radio solution design company iBIQUITY, commented that the HD Radio market is taking off. "HD Radio standard is based on current broadcast band, while DAB needs new high frequency band that involves licensing," said YongHong.

However, the price of HD Radio devices is still quite high, up to $300, and this has restricted the development of the technology in more countries.
