Two things led to the IBOC solution in the U.S.: 1) There was no spectrum available for a digital-only service. 2) Broadcasters wanted an IBOC solution because it did not require the purchase of additional spectrum or licenses. Now there's talk of a new digital-only band in the space where analog TV channels 5 and 6 used to be. This would be especially well suited to low power FM stations. It would likely use iBiquity technology as well because the silicon used for HD Radio could be easily modified for the new band. With the low power stations moved off of FM there would be less of an issue with increased power on HD FM causing interference to those stations. The big issue with HD right now is that the power levels are too low to provide equivalent coverage to FM. The addition/adoption of HD has striking parallels to the addition/adoption of FM radio in the 20th century. It took FM 40 years to become as ubiquitous as AM. Those that complain that HD is taking too long to become ubiquitous have no understanding of the radio business and how hard it is to replace the installed base of receivers. In any case, it all is coming together for HD in the U.S. with huge increases in receiver sales, more vehicle manufacturers including HD, and the HD consortium deciding to assist smaller stations with the conversion to HD by helping with funding and engineering expertise that the smaller stations lack. Yes by simply Expanding the FM Radio Band and requiring all the new FM Radio Stations to be IBOC HD-Radio with a Cut-Off of Analog at 5 Years would hasten the migration of Radio Listeners to HD-Radio on the FM Band. Use the New FM Channels to migrate many of the Smaller and Lower Powered AM Radio Stations to the Expanded FM Radio Band. {Depopulate the AM Radio Band}. I will repeat myself -presently- The driving force in modifying Radio Listener Behavior is their Car/Truck When the number of Cars/Trucks on-the-road with IBOC HD-Radio is around 90% IBOC will be de-facto Adopted by the Radio Listeners in their Car/Trucks. That will take a Decade or more. Each of those new IBOC AM & FM HD-Radio Listeners will eventually buy a new HD-Radio for their Home and/or Office. Yes is a Decade Long View to gently transition to HD-Radio; by gradually expanding it's 'presence'. |
