In the UK, digital radio is not always well-received

DABMany thanks to my buddy, Dan, who shares this article from the Daily Mail:

“It was supposed to be the technology that would transform the way we listen to the radio.

But audiences condemned DAB – or Digital Audio Broadcasting – as a disaster yesterday because of the poor quality of the signal.

They complained that it cuts out in the middle of broadcasts, while others claim the technology is already out of date.

One even joked on Twitter that while we can now receive close-up photos of Pluto taken billions of miles away, he ‘still can’t get a good signal on DAB’.

DAB had been heralded as less prone to interference than AM or FM, but household appliances including microwave ovens, laptops, mobile phones and TVs have all been found to affect reception. Power lines and the weather can knock out digital signals, while signal strength can be reduced in built-up areas, in basements and inside buildings with thick stone or reinforced concrete walls.”

NORWAY TO SWITCH OFF FM IN 2017

Within two years from now, the shutdown of national FM-networks begins in Norway. The switchover will begin in the North and will be implemented region by region.

Thursday, the Ministry of Culture announced a national FM-switch off, to complete the transition to digital radio. Norway is making an historical move into a new radio era, being the first country in the world to decide upon an analogue switch-off for all major radio channels. With DAB and digital radio, listeners will be provided with more radio channels and greater diversity in content.

Chorus 4: The DSP chip that supports AM, FM, DAB, DAB+, HD Radio and DRM

FrontierSiliconThe London-based digital solutions company, Frontier Silicon, has announced a new DSP radio chip that offers a wide array of available modes and is even DRM ready.

I have seen no specifications for this chip yet, and do not know if it covers the shortwave radio spectrum.

Still, this might be the perfect chip to allow radio manufactures to design an inexpensive, fully digital product in countries where digital platforms are gaining strength (anywhere from the UK to India, for example).

Many thanks to Rob De Santos for apprising me of this. I’ll post the specifications when they become available. Read the full press release below:

Chorus 4 a single-chip solution, integrating four previously separate chips

London, 17th December 2013

Frontier Silicon announces details of Chorus 4, its next generation digital radio chip. Chorus 4 is a single-chip solution, which integrates four previously separate chips to deliver significant cost and energy consumption savings.

Chorus 4 is the fourth generation chip from Frontier Silicon. The chip is designed to encourage the continued advance of digital radio around the world by supporting all major global digital radio standards. Chorus 4 provides solutions for multiple devices, including consumer radios, the automotive aftermarket and, for the first time, smartphones and tablets. The company’s previous solutions have already powered over 20 million digital radios worldwide.

The key features and benefits of Chorus 4 are:

  • Low cost, single chip solution: integration of RF front-end, baseband, application processor and DAC (“four chips in one”) delivers significant cost savings which enable high quality, entry-level price point digital radios
  • Ultra-low power consumption – one month’s listening for 5-6 hours a day on a portable radio with four D cell batteries (comparable to FM performance)
  • Multiple solutions for portable and table-top radios, smart-device docks, wireless speakers, hand-held receivers, sound-bars and audio systems
  • Automotive aftermarket – solutions for head units, integrated convertors and low cost adapters
  • Smart devices – enables digital radio solutions for mobile phones and tablets
  • Bluetooth connectivity – connecting smart devices and digital radios to enable hybrid radio (with interactivity and additional content delivered via IP), music streaming and remote control
  • Integrated service guides – new software will enable listeners to select stations from a single list of digital and analogue stations regardless of platform
  • Multiple radio standards – including support for AM, FM, DAB, DAB+, HD Radio and DRM

Digital Tick compliant – Chorus 4 solutions meet all technology requirements of the UK minimum specifications for both domestic and automotive digital radio devices.
Frontier Silicon CEO, Anthony Sethill, said

“Chorus 4 represents a step change for the digital radio market. After ten years of development on this and previous solutions, we now have our fourth generation chip – an integrated, single chip offering enhanced functionality, lower cost and significantly greater energy efficiency. Chorus 4 will power multiple devices, including low cost automotive adapters and devices with Bluetooth connectivity. For the first time, digital radio in mass deployment smartphones will become a viable proposition. As a multi-standard chip, Chorus 4 will address emerging opportunities around the world. I look forward to working closely with broadcasters, transmission operators and device manufacturing partners to address these exciting opportunities.”
