HD Proponents Seek Protection for “No New Spectrum”

An interesting trial-balloon was floated last month in Radio World. In it, John Kean, one of the founding employees of NPR Labs (who was let go in a reshuffle this past August) suggested that the FCC’s spectrum allocation rules be revised to better “protect” FM-HD Radio sideband signals.

Before going any further, it’s best to cover some history. HD Radio was adopted by the FCC in 2000 primarily on the premise that the system used “no new spectrum.” In fact, FM-HD signals double the spectral footprint of FM stations — but HD’s proponents got around this by appropriating fallow spectrum the FCC leaves between stations as the stations’ own allocation.

NextRadio Cuts Costs to Spur Adoption

It’s been a good year for NextRadio. The Emmis-developed smartphone application that enables FM listening on compatible devices is making great headway with wireless carriers. After paying Sprint to become the first-adopter, well-coordinated lobbying and social media campaigns this summer convinced T-Mobile and AT&T to request that the device manufacturers they work with enable FM reception. (Verizon remains a holdout, but that campaign continues).

With the consumer-side adoptive trend gaining momentum, efforts are now afoot to bring more broadcasters into the NextRadio fold. The back-end system that broadcast stations interface with is called TagStation; it maintains the NextRadio directory, provides all images and supplementary content to the audio broadcast, and manages the in-app advertising experience. Stations can sign up with TagStation for free, which means they’ll be listed in the NextRadio app and can display their logo to users. Read More

AM Revitalization Order Released

At the close of business last Friday, and with little fanfare, the FCC released its first AM revitalization Report and Order. This rulemaking began two years ago and the most significant outcomes have little to do with the AM band itself.

Comparing the FCC’s proposed rulemaking to the R&O shows that most of the agency’s initial proposals will be enacted. This includes things like allowing for more flexbility on interference calculations and protections, antenna siting and design, the option to use analog transmission protocols that are more energy-efficent, and increased utilization of AM’s expanded band channels. But the meat of the R&O involvews developments regarding the FM band and the utter lack of comment on a digital strategy for AM. Read More

No HD Bounce From Radio Show

The latest NAB Radio Show has come and gone, and there was little news about the HD Radio system other than the addition of new automobile makes and models to the company’s roster (including some GM models that had dropped HD last year). Not totally surprising considering that iBiquity’s just been acquired, and I’m sure the folks there and at new parent-company DTS were pretty preoccupied over the last couple of months with the deal.

But I did stumble across some interesting observations online that suggest there’s no rekindled love affair between HD and the industry just yet. In fact, folks still seem to be coming to grips with the fact that the technology still exists. The first is from Art Stone, the proprietor of Streaming Radio Guide. He scraped iBiquity’s directory of HD-enabled stations and crunched the numbers. iBiquity lists 3,818 “current HD based broadcast Channels.” This number counts all HD program streams, including HD-2/3/4 streams, and includes international broadcast licensees.

HD Radio Sells Out

It’s not quite the IPO payday that iBiquity Digital Corporation’s investors had been hoping for, but it does absolve the company of trying to jumpstart radio’s digital malaise on its own. Last week, iBiquity annonunced it was being acquired by DTS in a $172 million deal.

Who is DTS? Perhaps best known for developing multichannel surround sound technology for the film industry, the publicly-traded company now offers a range of digital audio encoding and processing algorithms that can be found in a variety of media formats and electronic devices. Read More
