Top Techs Have No Desire To Lose Spectrum

Panelists at the HPA Tech Retreat agreed with PBS's Eric Wolf: “Channel sharing is a reasonable option for people to look at, but at the end of the day management has to look at this and say we can take a one-time infusion of cash from the auction and give up forever some portion of our spectrum, which is our bread and butter, and forgo a lot of future options." But panelists weren't in harmony on every issue. CBS's Bob Seidel (l) and Sinclair's Mark Aitken disagreed on the approach to the next-gen TV standard ATSC 3.0.

While the FCC may want broadcasters to surrender some or all of their spectrum back to the commission for auction to broadband wireless providers, a panel of top broadcast TV tech experts says “no way.”

That topic, along with plenty of other hot-button issues — including spectrum re-packing, channel sharing, 4K/ultra high-definition acquisition and delivery, AFD (active format description), unbundling of subscription TV packages, software defined networks, IP broadcasting and ATSC 3.0 — were explored at the annual Broadcaster Panel at the recent HPA Tech Retreat in Indian Wells, Calif.

A highlight of the HPA conference for many attendees, the panel is a one-hour discussion featuring the top technology executives from major broadcast networks and TV station groups.

Moderated by Ericsson’s Matthew Goldman, this year’s panel featured Anthony Caruso from the  Canadian Broadcasting Corp., Bob Seidel from CBS, Dave Seigler from Cox Broadcasting, Richard Friedel from Fox, Eric Wolf from PBS and Mark Aitkens from Sinclar Broadcast Group. 


Starting with the topic of spectrum repacking, sharing and multicasting, broadcasters were in general agreement that although there may be some stations that want to cash out in the auctions, it does not make sense to permanently give up spectrum that might be used later for a variety of services delivering everything from mobile to 4K.

Brand Connections

PBS’s Wolf raised the point that although today’s encoders make channel sharing a viable option, advances in technology cannot solve the thorny contractual issues of how a for-profit station can share spectrum with a nonprofit PBS station, or whether it makes commercial sense to do so at all. 

“Channel sharing is a reasonable option for people to look at, but at the end of the day management has to look at this and say we can take a one-time infusion of cash from the auction and give up forever some portion of our spectrum, which is our bread and butter, and forgo a lot of future options,” Wolf said.

Siegler agreed, saying that Cox sees surrendering spectrum as limiting the future, and that the company has “no interest” in turning over any of its spectrum.

Sinclair’s Aitken went further: “No matter what happens, if the next generation of broadcasting is planned using legacy ATSC 1.0 and MPEG-2 standards, everyone will be ‘half of a broadcaster’ because what you can do within the limitations of ATSC 1.0 is only half of what broadcasters are capable of doing.”

Aitken added that “any consideration of channel sharing would have to go hand-in-hand with the notion of advancing broadcasting to the next-generation broadcast platform,” which he described as being all IP-based and capable of supporting both mobile and fixed services, which Sinclair believes will be vital to the livelihood of broadcasters in the future.

According to Seidel, the issue comes down to quality for CBS, so channel sharing is out of the question. The network always strives to deliver maximum quality, so until very recently CBS has used its entire 19.3 Mbit/s for HD. Recent advances in compression have enabled CBS to lower the bitrate slightly, freeing up approximately 1.5Mbit/s for a subchannel.


The industry’s top techs were also in broad agreement on 4K — delivering it over the air is not a priority.

“We’ve done a lot of testing of 4K in our labs, and you know what, it produces the best HD pictures we’ve ever seen,” said Fox’s Richard Friedel. “We think there is some there is some viability for 4K sets for consumers, but that’s not to suggest that we will be broadcasting 4K any time soon.”

Aitken put it more bluntly: “4K is not going to happen for broadcasting until ESPN says so.”

Seidel says CBS is a fan of 4K — for acquisition. He described how CBS/CW program delivery specifications include separate elements for acquisition and delivery. “On the acquisition side, our philosophy has always been that we want to maintain the highest possible quality levels so that we ensure the residual asset value of that content.”

Accordingly, for the past two years the CBS/CW specifications have allowed for acquisition in 4K, although this is not mandatory today. “Having an edited 4K master on the shelf is going to add to the asset value in the future, no matter how it’s distributed.”

On the sports side, CBS and others have been using 4K for acquisition (CBS used six 4K cameras at the 2013 Super Bowl), and using this content to extract HD content, as well as for super slow-mo replays. 4K/UHD will continue to be used in this way for sports productions.

It was Dave Siegler from Cox Media, whose parent company is also a major cable operator, who expressed disappointed in the downgraded signal that cable companies deliver to the home with compression, and asked rhetorically whether 4K delivered to the home would look as HD should.

You go, Mark Aitken! While channel sharing is an option it brings with it "thorny contractual issues" as one participant at the HPA Tech Retreat put it. It's a solution no broadcaster wants. The bottom line is that giving up spectrum today for a one-time payout, means forever forgoing any future potential for it. This is a fact broadcasters get and why selling the industry on incentive auction participation is going to be a hard, uphill climb for the FCC.

I believe Michael Dell would disagree with you. He's been buying up under-performing stations hoping to see their spectrum sold at auction.

I'm talking true broadcasters, not bottom-feeding speculators. And I didn't see his name or the name of his company on the HPA Tech Retreat roster either.

Broadcasting is so 1992. The audience share for OTA is miniscule, much less than 10%. -- what a waste of spectrum. Go google the "Negroponte switch" and consider how ludicrous it is that cell phone users are denied bandwidth because broadcasters spin fantasies about future uses.

Rustbelt, your so fun... Saying the same thing that wasn't true in 2009 and definitely isn't true now. I mean try selling your broadcasting is "way less" than 10% to the antenna manufactures like Winegard, Channel Master, Antennas Direct, and Mohu. The list keeps growing everyday. All these old and new names releasing new products to service a dying industry. Someone is a bit slow on the up take, but I don't think it is them. And, like you say, you're stuck in the 1990's.

    Easily fall’s best broadcast network comedy pilot, NBC’s The Good Place offers a clever high-concept premise that’s complemented with intelligent, sometimes absurdist humor. Created by Michael Schur, co-creator of NBC’s Parks and Recreation, The Good Place is a highly serialized series that’s essentially set in heaven and stars Kristen Bell and Ted Danson. NBC made five episodes of The Good Place available for review, and the show not only holds up, but also it improves, deepening characters that initially feel one-note and frequently leaving viewers guessing with cliffhanger endings to many of the episodes. The combination of snappy dialogue and winning but flawed characters makes The Good Place a great bet for fans of smart TV comedy.

    Pitch has swagger, for good reason. It gets the big things right; the Fox drama about the first female baseball player in the Major Leagues is one of the year’s most assured and exciting debuts. But part of what impresses about the pilot is also the way it confidently strings together so many small but telling details. Ginny (Kylie Bunbury) is the first woman to be called up from the minors to the big leagues, and no show since Friday Night Lights has done a better job of portraying the internal and external pressures that weigh heavily on young athletes asked to do much more than merely succeed on the field. Pitch will likely do a good job of getting viewers to root for it. The hope is that the show won’t be an impressive, short-lived curiosity, but rather a long-term phenomenon.

    In a fall TV season that’s already making a splash for championing diverse, distinctive voices in an array of projects that they created, wrote, and starred in, Better Things on FX stands out. The show is created by, written by, and starsPamela Adlon. She plays Sam Fox, the single mother of three daughters modeled after her own reality-show-ready experience raising three girls in Los Angeles following a divorce. Sam is also, like Adlon, a working actress — on shows both raunchy, a la Californication, and animated for children, like her role on Recess. It’s a refreshingly blunt take on single motherhood without sacrificing the warmth of parental love, portraying the dance between selfishness and selflessness that’s at the heart of being a parent — especially one weathering the hormonal fireworks of a household of four women at different ages.

    The fall TV season doesn’t count as much as it used to — we already know that. But no matter how many retreads the broadcast networks throw at viewers in the next few months, this fall will be memorable because of the premiere of Atlanta on Tuesday, Sept. 6, on FX. The half-hour comedy created by and starring Donald Glover (Community), simply and brilliantly recalibrates our expectations of what a TV comedy is and how black lives are portrayed on the medium.

    The second reboot of the 1980s John Candy movie Uncle Buck, bumped by ABC from midseason, has the same tired jokes you'll find on any second-rate sitcom. Too bad, because Mike Epps is appealing and ABC would be wise to keep him around for future shows, but there’s just not enough to this show to suggest it will last past summer. It also airs against NBC’s America’s Got Talent, summer’s No. 1 program on broadcast, which may make it even harder to find an audience.

    Bryan Cranston brings his Tony Award-winning interpretation of President Lyndon B. Johnson to television in an adaptation of the Robert Schenkkan play All the Way, and it’s still quite a sight to behold, just as it was on Broadway in 2014. Nothing beats witnessing this kind of larger-than-life portrayal onstage, of course. But the television version, presented by HBO, offers plenty of rewards, allowing Cranston to work the close-ups and liberating him from the confines of a theater set. Cranston’s performance is a gem — in his hands, this accidental president comes across as an amazing bundle of contradictions, someone who seems at once too vulgar for the job and just right for it.
