A rádio hertziana vive (com o HD)

"If you think that terrestrial radio is dying, think again. HD radio, with multicasting and CD-quality sound, is growing by leaps and bounds according to last week's National Association of Broadcasters (NAB) Radio Show in Philadelphia. "Broadcasters are converting stations at a pace of more than one per day as they ramp up efforts," said Robert Struble, president and CEO of iBiquity Digital Corporation. "There are now stations from Philadelphia to Seattle broadcasting additional streams of content." HD radio allows for the multicasting of multiple channels on the same radio frequency. And commercial stations are not the only ones making the change. Not to be left behind, the Corporation for Public Broadcasting (CPB) announced an agreement at the conference with iBiquity to accelerate the conversion of 400 stations nationwide. iBiquity is the sole developer and licenser of HD radio technology in the US. A total of 500 stations in the US are now capable of broadcasting in HD.

Satellite radio providers have been standing by to play taps for terrestrial radio for some time. The only problem is that traditional broadcasters have refused to play along, hoping the growth of HD radio will breathe new life into the medium. Now, the move by the CPB will help to push things further.
Most recently, a Washington DC-based NPR station broadcasted the confirmation hearings of Supreme Court appointee John Roberts via an HD multicast. But getting HD radio in front of the public is only half the battle, as consumers must ultimately accept the new technology. The kind of experimentation that is available through public radio can provide a soapbox, so to speak, for HD radio to be heard."
