2017 came and went with no great movement in the HD Radio space. According to FCC records, fewer than 2,000 FM stations have received authorization to broadcast in HD, which represents an adoption rate of 15% – a number that has not changed significantly during this decade.
On the AM side, although some 240 stations (5%) are authorized to broadcast in HD, this curated list shows that about half of them have abandoned the protocol. Penetration of HD receivers into the automotive space remains at just under half of all new cars sold in the United States and there’s still no meaningful market for non-automative portable receivers.
Yet the broadcast industry would rather you believe that HD is thriving. A new “e-book” from the folks at Radio World, New Directions for HD Radio, contains useful information about ways to optimize the system, including making sure that the analog and digital signals are properly time-aligned, the necessity of seamless audio processing across the airchain, and National Association of Broadcasters effort to standardize the broadcast of metadata on HD signals. One would think those core operational principles would’ve been hammered out nearly twenty years ago when the technology was first authorized for deployment, but it was more important to the industry to make a digital beachhead on the airwaves than it was to deploy something that worked out of the box.

One of the largest controversies involving the U.S. digital radio standard, HD Radio, has been its proprietary nature. The technology’s owner,
iBiquity DTS Tessera Xperi Corporation, has refused to make public all the necessary technical information within the standard, dubbed by the National Radio Systems Committee as NRSC-5; this ostensibly prevents anyone from developing or manufacturing any HD-related transmission or reception technologies without express licensure from Xperi.
The specific “black box” that has kept the technology proprietary has been the algorithm Xperi uses to encode and decode HD audio signals. If you look at the publicly-available NRSC-5 documentation, you find no meaningful detail about this aspect of HD technology beyond a description of how it works.
This was a site of controversy during HD’s tortured development: initially, the standard was to utilize an algorithm derived from publicly-accessible code – but once the FCC gave the standard its blessing, then-developer iBiquity swapped out the codec under which the technology had been tested with a new one that it had ginned up wholly in-house. But it performed so poorly that HD’s proprietors replaced it again with the variant onboard transmitters and receivers today. Continue reading “HD Radio Cracked on Receiver-Side”
Another LPFM station has taken the plunge into the HD Radio space: introducing KVCB-LP, run by the Vacaville (CA) Christian Schools. KVCB is the second LPFM station to be authorized by the FCC to broadcast in HD – the first was WGVV-LP in Rock Island, Illinois, which received FCC authorization for digital broadcasting last decade, though it’s unclear if the station ever deployed it.
KVCB-LP was the brainchild of music teacher and genuine prodigy Ralph Martin, who’s long had the radio-bug: in 1997 he built a network of Part 15 AM transmitters for the students to use, and when the LPFM service was initially authorized in 2000, Martin made all the necessary plans to apply for a license.
Congressional meddling into LPFM – namely, tightening the interference-protection standards on these small stations – meant that Vacaville went from having potential channels available to having none. But Martin bided his time, and when Congress undid many of the restrictions on LPFM earlier this decade and the FCC opened another application-filing window, he was ready. Construction permit in hand, the station went on the air, initially analog-only, in 2014. Continue reading “LPFM + HD Radio = 💰🔥”
The closure of Tessera Technologies’ purchase of DTS Inc., the owners of iBiquity’s HD Radio system for just one short year, is set for sometime in December, and the combined companies will adopt a new name and stock symbol on NASDAQ in the new year. But just how much did the HD system itself drive its sale twice in 14 months, and what are the prospects for its future development?
Turns out, not very much on both counts: buried at the bottom of a story published by iHeartMedia-owned Inside Radio in early November was this gem: “DTS had been in sale mode since June 2014 when it was first approached with a $29-$32 per share buyout offer that proved to be too low for the board’s approval. But it set into motion the process that ultimately led financial advisors to shop the company. Tessera first appeared on the radar in August 2015 — two months before DTS bought the HD Radio business from iBiquity — and those discussions continued for months [emphasis added].”
In other words, DTS had put itself up for sale before negotiations began to acquire the United States’ troubled digital radio broadcast platform. And in fact, two months before DTS actually bought iBiquity and the HD system, it had already received acquisition-inquiries from Tessera. At the time, DTS’ board of directors considered the sale-price per-share too low…but what better way to bump that up to a more lucrative level then to acquire some additional intellectual property for the corporate portfolio?

It came as a surprise to attendees of last week’s NAB Radio Show in Nashville: just a day before the CEO of DTS, the company who bought HD Radio proprietor iBiquity just last year, was to be a featured guest at a convention luncheon, his company was acquired by Tessera Technologies in an $850 million deal.
Who is Tessera? Founded in New York back in 1990, the company initially began as a designer and manufacturer of semiconductor chipsets, including memory modules. It went public on the NASDAQ stock exchange in 2003; five years later it acquired FotoNation, a company devoted to image analysis. Continue reading “HD Radio: Sold…Again”
Earlier this summer Radio World published one of its occasional special “e-books,” this one called “HD Radio From the Ground Up” (form-filling required to download). Like most industry trade publications, it’s a celebratory document that seeks to paint the U.S. digital broadcast system in the best possible light.
Kicking things off is a tech-centric column from Scott Fybush in which he talks with various enginerring principals about the efficiency of today’s FM-HD Radio systems. Unlike the first few generations of the tech, which involved wildly inefficient combination of the analog and digital signals, improvements to the HD system now make for a better marriage. In HD’s early years, more than 30 percent of the power that went into the analog/digital combination process was lost as waste heat; now that number is down to something like 10 percent.

After its lackluster appearance at the NAB Show earlier this year, HD Radio‘s new owners, DTS Inc., are trying mightily to demonstrate that the technology remains a viable future for broadcast radio. In May, DTS announced its first-quarter financials, representing the first full quarter of its ownership of iBiquity. As expected, the acquisition had a positive effect on DTS’ bottom line, no doubt from the revenue stream involving licensing HD receivers in cars (for which the company gets paid as much as $12 per unit).
Presently, however, HD Radio is found in just 37% of all new vehicles sold in the United States — a far cry from widespread penetration, but more than enough to move the needle in DTS’ ledgers. According to a company conference call earlier this year, the acquisition of HD Radio is part of a pivot by DTS away from developing/acquiring audio enhancement systems for home entertainment technologies (which are on the decline) and toward the mobile and portable device spaces (which are growing mightily). By the end of 2016, DTS expects its automotive division (which includes HD Radio) to account for some 40% of all revenues. Continue reading “HD Radio: "We're Still Here"”
According to reportbacks from the just-concluded NAB Show in Las Vegas, it was a lopsided affair in favor of the future of television. And why not: broadcasters stand to make billions over the next year selling off their spectrum, and those who stay on the air will be rolling out a new digital television standard with new content and datacasting potential.
Meanwhile, the radio industry’s been rocked back on its heels by a slew of bad fiscal news. iHeartMedia, for now, has managed to stave off several billion dollars’ worth of its debt being called in early by angry bond-holders, but the company’s effectively now engaged in increasingly nasty legal maneuvering to decide its debt end-game sooner rather than later. #2 conglomerate Cumulus Media’s still squeezing its broadcast properties also in hopes of keeping bankruptcy at bay. Emmis faces delisting by NASDAQ in early June. Even the relatively fiscally-sound CBS has announced its intent to spin off its entire radio division into a separate company, selling it also seems to be an open option.

2015 was a potentially pivotal year for HD Radio, if only for a changing of the guard in the system’s ownership. In September, audio technology company DTS Inc. announced the acquisition of iBiquity Digital Corporation, the proprietor of the HD Radio Standard, for $172 million. Last month, DTS’ chairman and CEO, Jon Kirchner, penned a paean to the technology in an industry trade.
Calling HD “the biggest advancement in terrestrial radio broadcasting since the advent of FM radio,” Kirchner is obviously very upbeat on the technology’s prospects. His biggest hope is pinned to using HD Radio as a pipeline for “wider adoption of HD Radio and various DTS technologies,” supposedly working in concert, primarily in the automotive space. This, Kirchner believes, will foster an “independent and neutral [digital radio] platform for the radio industry.”
Two weeks after penning this missive, DTS announced a management shakeup at iBiquity. Founding CEO Bob Struble has been set aside (to become a “special advisor” to Kirchner) while iBiquity chief operating officer Jeff Jury was promoted to a new managerial-level position within DTS responsible for both “Automotive” and HD Radio. Continue reading “HD Radio's High Hopes for 2016”
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.
