Kurt Hanson and Mark Ramsey -- others, too -- continue to take shots at HD Radio (see Black Friday for HD Radio in hear2.0). At its present state of deployment by iBiquity, the CE world and us broadcasters, those shots are probably deserved. Multicasting was an improvement and there are some neat enhancements in development. But the HD Radio vision needs revitalizing even before it's reached a single digit percentage of market share.
Revitalizing means rethinking radio along lines that are making its non-transmitter competitors so attractive to so many (or maybe I should say too attractive to too many). We need to retool HD Radio as an open platform, something that its SMIL mark-up language encourages. I've written here in the past about one way to do it (apparently to zero effect) that I was calling a many-to-many radio, but I'm sure there are others. Give each radio station program channels limited only by how much of both kinds of IP they can buy. Then give each listener the ability to customize channels to his or her preferences and listening habits. This isn't brain surgery, folks.
Great minds think alike update. I'd just posted the above when I ran across John Proffitt's very good post, iBiquity: How a closed-source model is killing HD Radio. Covers much of the same ground as mine, but more thoughtfully. Link: Gravity Medium. --Dennis
