FCC: Market to Decide Fate of HD Radio

On March 22, the Federal Communications Commission removed the final administrative hurdles to allowing the full-scale rollout of in-band, on-channel (IBOC) “HD” digital radio in the United States. It’s a huge win for the industry, though the public benefits remain to be seen.
According to staff testimony at the meeting (which starts at ~1:01:00), the FCC appears unconcerned with HD Radio’s potential pitfalls and more than willing to let the industry set the pace of radio’s analog/digital transition. According to Ann Gallagher, an engineer in the Audio Division of the FCC’s Media Bureau, “substantial additional testing” by iBiquity and the National Association of Broadcasters justifies the expedited deployment of HD Radio. Stations may now commence multicasting and separate their analog and digital antenna systems without formal FCC approval. Continue reading “FCC: Market to Decide Fate of HD Radio”

Public Interest Obligations for Digital Radio?

When TV broadcasters were given access to new spectrum in order to establish digital channels late in the last decade, the grants were contingent on broadcasters using the spectrum-windfall in ways that served the public interest. This might include things like opening up a slice of each DTV channel to public access, or obligating DTV stations to produce “public-interest” programming with news, educational, or other civic-minded value.
The problem is that while the FCC’s been talking about public-interest obligations for DTV broadcasters for 12 years now, it hasn’t adopted any explicit rule defining what those obligations are, and how stations must comply with them. Meanwhile, DTV stations are going on the air and the spectrum they use – touted as having the capacity to offer as many as six different channels – is being utilized however broadcasters see fit, and this often has nothing to do with providing more free over-the-air content.

Clear Channel: Sold

As a rudimentary reading of the tea leaves has shown, Clear Channel has elected to go private, accepting a buyout offer of nearly $19 billion from two private investment firms. On the same day, Clear Channel announced it would divest its holdings of radio stations outside of the top 100 markets – just under 39% of its total station inventory, minus those small cluster-sales it has already made over the last couple of months.
It’s anybody’s guess what a leaner, meaner private Clear Channel may mean; regulatory review and approval of the deal will be required. There already may be a shareholder lawsuit in the works, too. Continue reading “Clear Channel: Sold”

FCC Punts on HD Rulemaking

Thursday’s Commission meeting was delayed by five hours; during the delay the agency revised the meeting agenda, announcing that the digital radio item had been pulled. No reason given, except, “it isn’t done.” One could say the same about the HD Radio protocol itself, but that’s not stopping radio’s major players from shoving it onto the air.
In related news: how much fresh content does digital radio multicasting really offer? Most HD-R side-channels run what is called a “hard clock,” meaning a set playlist with few or no updates. According to Mark Lapidus, “When they [reviewers of HD radio receivers] don’t discover the repetition, I figure that they just really haven’t listened very much. However, real listeners will catch on quickly as they hear the same song at the same time every day.” What kind of content diversity does one expect when the largest provider of HD multicast programming is Clear Channel?

FCC to Further Rubber-Stamp IBOC/HD Radio

The Federal Communications Commission’s monthly meeting goes down on Thursday, and the second-to-last item on its agenda is the adoption of a Further Notice of Proposed Rulemaking on the certification of “HD Radio,” the digital audio broadcast technology of-choice for the U.S. radio industry.
Though the HD Radio system has not yet been formally certified, a relatively vigorous campaign is underway to deploy it. Rush deployment before formal certification of a technology results in what is called “the creation of facts on the ground,” demonstrating the technology’s functionality and increasing the pressure on its regulator to approve its usage (since it’s already out in the wild, failing to certify it puts the regulator in the position of nullifying billions of dollars of investment).

Radio Convergence: The Next Step

The definition of “radio” just got more complicated. Walk into any big-box electronics store and ask for “digital radio,” and they’ll (more likely than not) point you to XM and Sirius satellite receivers – much to the consternation of terrestrial radio broadcasters, who want their “HD” technology to be synonymous with “digital.” Receiver manufacturers are also blurring this boundary – one will soon roll out a receiver which is both XM and HD-compatible.
Now, XM has filed for a patent on the process of taking an XM satellite radio signal and rebroadcasting it as one of the channels on an HD-equipped FM radio station. This is actually somewhat easier than it might sound, because the audio encoding algorithms used by HD radio and satellite radio are related – they’re products of Lucent Technologies. Lucent has not only licensed its codec technology to XM and Sirius, but it’s a partial-owner of iBiquity Corporation, the company that owns the HD radio technology.

Public Broadcasters Want Digital Interference Examined

The Corporation for Public Broadcasting seeks proposals to conduct a study of digital radio interference – both existing and projected – in 75 radio markets around the country, including the top 50. According to the RFP announcement, “CPB is concerned with the disenfranchisement of listeners due to the loss of services public radio currently provides to them and the underperformance or lack of HD service…when the conversion of public radio stations to HD is complete.”
The document itself notes, “CPB has received reports that existing analog listeners have lost reception of their favorite public radio station when new HD signals have gone on the air.” Continue reading “Public Broadcasters Want Digital Interference Examined”

IBOC Reception and Politics Panned

Interesting hubbub in the trades surrounding the first digital radio-compatible receiver to hit the U.S. market, the Boston Acoustics Recepter HD. For $299 it promises to “receive and seamlessly play” HD Radio signals, including the new multicast channels some HD-equipped stations have begun broadcasting. But when a New York-based broadcast veteran plunked down the cash and got the box home, he found it didn’t work as advertised.
I went to the Ibiquity Web site to find that there were at least 13 stations broadcasting in HD in New York. One by one I tried to tune them in, and one by one I was met with frustration. Constant fiddling with the antenna yielded part-time successes. I managed to get Z100’s second channel for about three seconds, then three seconds of dead air, then on, then off….

IBOC Update: HD Radio in the Media, Court

The issue of interference involving digital radio broadcasting on the AM band using the IBOC protocol has made it into the corporate media. The Wall Street Journal ran a piece earlier this month on the problem. However, smoothes it over as an “unexpected consequence,” which is false: the interference is due in part to the very design of the HD Radio system. Digital-related interference also affects FM transmissions, though not nearly as severely.
The article does note that Leonard Kahn, inventor of the CAM-D AM digital broadcasting protocol, has filed suit against iBiquity on antitrust grounds. As iBiquity’s backers are essentially the major broadcasters and consumer electronics manufacturers, Kahn accuses the “cartel” of imposing a proprietary digital radio standard on the country before the FCC’s had a chance to evaluate competitor technologies like his.
