USATODAY.com - Digital radio emerges into the future
After getting a lackluster rollout from both radio stations and manufacturers last year, digital radio is finally gaining some traction. Hundreds of radio stations have gone digital in recent months, and retailers are starting to offer digital radios for homes as well as cars.
Analysts and broadcasters say digital radio will bring listeners better sound quality, as well as new programming choices. That should generate fresh revenue for an aging medium under siege from satellite radio and the Web.
'Without (digital), the radio industry signs its death warrant,' says Gartner analyst Laura Behrens. 'With it, the industry has a chance to reinvent itself.'
Digital radio can revitalize AM stations by making them sound like analog FM, and can juice up FM stations with CD-quality sound. Perhaps more significantly, the digitized signal can be compressed to let FM stations broadcast at least one or two additional channels at the same frequency. Digital radios also display a song's title and artist on a small screen.
On the way for digital AM and FM: on-demand traffic, weather and stock updates, via text or audio, and the ability to pause or rewind a live song. Eventually, you'll even be able to push a button to order a CD of the song on the radio.
