Gearing Up For NAB: Cellular ENG

Bonded Cellular Is ENG's Next Frontier

Six companies — LiveU, Dejero, TVU Networks, Streambox, Teradek and DSI RF Systems — have emerged as pioneers on the cellular video frontier. A seventh, Vislink, is about to enter the market. Each manufactures a portable device that uses AT&T, Verizon, Sprint and T-Mobile air cards to produce a signal capable of transmitting high-quality pictures.

When news broke on the morning of Feb. 27 that a student gunman had terrorized Chardon (Ohio) High School, Cleveland TV news crews raced to broadcast live from the scene of the shooting.

Most floored their satellite or microwave trucks down Route 6, then scrambled to run cable and establish signals — tedious processes that delayed their live shots. But the crew from Gannett's WKYC had a secret weapon that got its reporter on the air minutes after arrival.

Story continues after the ad

Still en route, the crew from Cleveland’s NBC affiliate turned on a device manufactured by LiveU that allowed it to broadcast live video over the same cellular networks people use to make phone calls.

“We really won that story,” recalls veteran WKYC videographer Barry Wolf. “We were on-air at least an hour before ground crews at other stations even powered up.”

For decades now, television stations have used satellite and microwave technology to beam video from the field back to control rooms. The requisite equipment is dependable, but expensive and cumbersome. A single truck can cost several-hundred thousand dollars. At the scene of breaking news, setup takes 30 minutes or more. Some locations — the inside of a school, for instance — are unreachable without long, unwieldy cables.

Increasingly, TV stations like WKYC are transmitting video from the field wirelessly via the Internet. To achieve the bandwidth needed to stream broadcast-quality video, and to boost the odds of making a strong connection, TV crews are employing devices that “bond” signals from major cellular carriers’ 3G and 4G networks.

Six companies — LiveU, Dejero, TVU Networks, Streambox, Teradek and DSI RF Systems — have emerged as pioneers on the cellular video frontier. A seventh, Vislink, is about to enter the market. Each manufactures a portable device that uses AT&T, Verizon, Sprint and T-Mobile air cards to produce a signal capable of transmitting high-quality pictures.

And each will be at this month’s NAB Show in Las Vegas, pitching its product as the future of live video.

Future is the key word. Even the biggest believers in cellular video transmission — the executives whose livelihoods depend on it — concede the technology is not developed enough to supplant its predecessors.

“I’m not going to say that we’re a replacement for a satellite or microwave trucks,” says Jon Landman, VP of sales at Teradek. “That’s not fair because when there’s that one story that everyone is running to and you need a guaranteed feed to be supplied, microwave or satellite can give you that.”

“We all have the same problem,” adds Dejero founder and CEO Bogdan Frusina. “We can’t give [customers] reliability. Reliability is only given with the classical sort of transmission, which is Ethernet, satellite and microwave."

What cellular video can deliver is mobility (entire broadcast units fit in backpacks, suitcases or belt clips), speed (setup takes five minutes or less) and ease (the units are highly automated because, as Frusina says, “you don’t want to make a reporter who’s not a techie, be a techie”). The benefits often outweigh the risk of having to scrap a shoot because of poor reception.

“Having the satellite trucks is great for those high-profile events where you absolutely have to get the picture 100% of the time, and it has to look great,” says Mike Savello, LiveU’s VP of sales. “For every one of those events, there’s probably three or four other events where just having the news coverage is going to give you an edge over your competition in that marketplace.”

So, what is the chance that bonded cellular technology will fail on any given assignment? The answer depends on two chief factors: the strength of wireless signals in the area, and the availability of bandwidth.

Even as cellular companies expand their networks, dead zones still exist. If there are cellular signals to bond, bandwidth might be limited by heavy use, especially at major news events where — thanks to government-mandated net neutrality — journalists must compete with crowds of smartphone-wielding citizens.

As Savello puts it: “Our modems and our system don’t get any higher priority than some 16-year-old with a cell phone standing right next to us.”

But makers of cellular video transmitters can offer TV stations some advantages over the general public. Streambox, for instance, uses technology called the Avenir Range Extending Model to boost reception. LiveU has developed custom antennas that can pick up signals from faraway cell towers unreachable by phones. At some big-time news events, COWs (cell towers on wheels) provide extra bandwidth.

Manufacturers call these technologies proprietary, but competing cellular video devices are more similar than they are different. With the exception of DSI’s NewsShark, which is not yet 4G- or high-definition-capable, they all boast of superior picture quality and sub-second latency in good conditions (users can select from a range of latency settings). And they’re all beginning forays into the smartphone and tablet markets, producing apps that will make streaming video available to journalists and pedestrians en masse.

With the reliance on shaky iPHONE video uploaded from by standers, it is obvious that content is always more important than quality. In news quick and first is better than great production values and late for air. Let's look at today where we can edit in the camera and send it back to the station as a digital file as a completed package. It's also about saving money. If I can 'stream' video from a small camera over the WIFI, I don't need a sat truck and 3 people on the shoot. As soon as we get rid of the 'stand up' in the dark out side the courtroom where something happened 6 hours earlier, there won't be any need to go into the field. It will be back to 'live' from the car park out side the station and just mix in b-roll. Suddenly, Comedy Central The Daily Show with their Green Screen live reports, doesn't seem too far away from reality.

    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.
