With standards for digital radio approved, what is to follow?

The technology faces heavy competition in an increasingly crowded field of digital entertainment. And new digital receivers will cost $75 or $100 more than traditional radios at first, making it uncertain whether many people beyond audiophiles and high-end car companies will be interested.

If it does catch on in a major way, the biggest financial winner will be one company — iBiquity Digital Corp., a Maryland-based consortium of big broadcasters, media companies and researchers that spent $100 million developing the technology.

The Federal Communications Commission's Oct. 10 approval essentially gives iBiquity the exclusive right to license the technology to equipment manufacturers, application developers — anyone that wants to sell just about anything related to digital radio.

"At the end of the day this is what puts us in business,'' said Patrick Walsh", iBiquity's chief financial officer.

Walsh reeled off the key numbers for iBiquity: There are 70 million old-style analog radios sold in the United States every year, and 800 million are sitting in homes and cars. Eventually, he said, digital radios should replace nearly all of them.

Unlike satellite radio, a subscription service, digital radio is an enhancement to regular radio. It doesn't increase a station's range or allow for more stations on the FM and AM bands. But it does eliminate static and lets broadcasters transmit textual information — such as news updates, weather alerts, information about songs and call-in numbers for commercials — with the audio signal.

Future versions could let listeners set their radios to record programs days and months ahead of time, or while they are listening to other stations.

Listeners will be able to continue using their current radios, while those who buy new digital-ready radios will be able to take advantage of the additional information streams.

Those new digital receivers are expected to hit the market early next year, and iBiquity is trying to persuade auto manufacturers to make digital radios standard in new cars. That step figures to be helped by the fact that Ford Motor Co. and its parts spinoff Visteon Corp. are among iBiquity's investors, along with broadcasters such as ABC, Clear Channel and Viacom. There's nothing to prevent consumer electronics companies, by the way, from integrating both digital satellite and terrestrial tuners into a single receiver.
