LG, GatesAir Test Futurecast At WKOW Madison

GatesAir, LG and its subsidiary Zenith early this morning with the help of Quincy Group’s WKOW Madison, Wis., conducted an on-air test of Futurecast, a contender for the next-generation digital TV transmission in the United States.

The test, broadcast on WKOW’s ch. 26 (PSIP 27) is discussed in a press release issued this morning. A Web video recaps a low-key test of Futurecast from the station conducted during the summer.

In a telephone interview before the test, Brady Dreasler, chief engineer for Quincy Group, said he was impressed this summer with the robust nature of the Futurecast signal, which allowed mobile reception of the signal at 70 mph.

He also expressed enthusiasm for Futurecast’s ability to deliver a 4K signal throughout the Madison market — even to difficult indoor areas, such as inside a metal structure, including a local WalMart tens of miles from the transmitter.

To receive the Futurecast signal indoors, LG built an outboard, portable test receiver-demodulator and connected it to a 4K TV setup at  different indoor locations. A special van was equipped with a Futurecast receiver for the mobile test.

The tests this summer and early this morning were conducted from the station’s main transmitter site. The only modification necessary to put the station on-air with the OFDM-based Futurecast system was a change out of the transmitter’s exciter, said Jay Adrick, an independent consultant and former executive with Harris Broadcast (the predecessor of GatesAir).

FUTURECAST Summer 2014 Test

This summer GatesAir, Zenith and LG quietly conducted a test of FUTURECAST from WKOW-TV in Madison, as a preliminary field trial to today’s test.

While Dreasler was pleased with the coverage of the Futurecast system, both he and Adrick said many broadcasters will find it desirable to deploy Single Frequency Networks consisting of as many as four repeater sites on the periphery of their coverage areas with highly directional antennas pointed back in at the centers of their markets.

At both the 2014 NAB Show and IBC 2014, GatesAir conducted a technology demonstration to show how an OFDM-based system, such as Futurecast, could be used by broadcasters to transmit to LTE mobile phones using Future Extension Frames, FEF, and time division multiplexing.

The WKOW test of Futurecast did not include an FEF component; however, Adrick said future tests of the system may indeed have the ability to transmit to LTE handsets in this fashion.

Futurecast is one of several systems under consideration for the physical layer of the ATSC 3.0 next-generation over-the-air digital TV transmission standard.

KERO Replaces Control Monitors with Multiviewers

KERO, the ABC affiliate in Bakersfield, Calif., recently overhauled its Studio A control room and entirely removed its bank of SDI monitors. All were replaced with multiviewers.

The Studio A control room is used for evening news broadcasts. Instead of purchasing more than a dozen costly SDI monitors, KERO switched to four Matrox MicroQuad Multiviewers to be used with four 23-inch LG HDMI monitors to preview up to 16 SDI signals.Matrox_MicroQuad_with_Monitor

Five of the signals come from on-set cameras in Studio A, two come from traffic cameras and one shows weather graphics. Other video feeds come from broadcast trucks out on location or from Studio B, where events such as telethons and a yearly home give-away take place.

Michael Tamson, IS director at the station, says the price of Matrox MicroQuad was attractive and allowed the station save space in the control room while avoiding the cost of multiple SDI monitors. The video quality, he says, is excellent — allowing the staff to see all the details.

controlThe MicroQuad Remote control application runs on a Windows computer and lets users toggle between full screen and quadrant views, select the input channel, pick audio channels, as well as hide labels and the red input selection box. It also lets users create custom labels of up to 10 characters, which will be retained even when the unit is disconnected from the computer.

“In the past, we have used monitors with built-in multiview capability but we like the fact that the Matrox units are independent, so we aren’t tied to a certain monitor size,“ Tamson says. “When a monitor starts to go off color due to age, we can easily swap it out for a new one. Another nice touch is the screw-in power connector that prevents technicians from inadvertently disconnecting the units.”

Matrox MicroQuad are priced at $995 each.

LG, Harris Broadcast Unveil ATSC 3.0 Proposal

Sinclair, Several Others Submit ATSC 3.0 ProposalLG and Harris Broadcast have shed some light on what they think a next-generation television standard should look like.

In August, the two companies submitted a proposal for the physical layer of what’s being called ATSC 3.0, but declined to comment on what that proposal entailed. The companies said today that its standard, dubbed “Futurecast Universal Terrestrial Broadcasting System,” was developed as a next-generation system not just for the U.S., but for around the world.

LG developed the current ATSC broadcast standard used in North America today.

Notably, LG and Harris’ proposed solution doesn’t mention taking core technologies from DVB, the European standard, which has been included in several of the 10 proposals submitted to ATSC.

According to the companies, Futurecast is expected to increase data throughput by 30 percent, while maintaining reception coverage and improving multipath performance for fixed and portable TV reception — one of the primary goals of ATSC 3.0, as laid out in the call for proposals. A 30 percent increase in throughput would mean each channel could operate with about 25 Mb/s of spectrum.

When it comes to mobile TV reception, Futurecast includes energy-saving features for consumer receivers and enhanced indoor TV signal penetration, using flexible coding choices, according to the companies.

Included advanced modes will help deliver high data rates, or robust transmission capabilities, for things like 4K broadcasts, according to the companies.

The proposed system also aims to provide state-of-the-art error correction coding and signal constellations over OFDM modulation.

“Future television broadcast standards will require blazing new trails in many areas, starting with a transmission system that’s powerful, spectrum efficient, robust, flexible and extensible,” Skott Ahn, president and CTO of LG Electronics, said in a statement.

Futurecast aims to be as open as possible, in order to support future broadcast systems beyond ATSC 3.0, according to a release.

ATSC 3.0 is expected to move to a candidate standard in the next two years, with a final standard expected to come in 2016, says Mark Richer, president of the ATSC. This month, companies and individuals who submitted a proposal for ATSC 3.0 plan to meet and give a tutorial on their respective standard to the ATSC.

Sinclair, Several Others Submit ATSC 3.0 Proposal

Sinclair, Several Others Submit ATSC 3.0 ProposalThere’s big interest from several organizations in the next-generation television standard.

The Advanced Televisions Systems Committee received 10 proposals from 19 organizations for the physical layer of what’s being called ATSC 3.0 on Friday, Aug. 23, according to Mark Richer, president of ATSC. Detailed plans of those proposals are due at the end of September.

While there were some expected organizations — like the Digital Video Broadcasting (DVB) standard organization — that filed proposals, one of the more interesting proposals came from the nation’s biggest broadcaster.

Sinclair Broadcast Group, with nearly 40% coverage, is teaming up with Austin, Texas-based Coherent Logix, a maker of C-programmable processors for the embedded systems market, on a proposal for ATSC 3.0. Coherent Logix also specializes in video and imaging development systems (VIDS), according to its website.

ATSC 3.0 is a standard that’s expected to give broadcasters a platform to implement several technical advances, including 4K broadcasts, targeted advertising and stronger mobility. It’s currently on a four-year timetable to have a final standard completed by 2016.

Other companies interested in developing a physical layer for ATSC 3.0, several of which filed joint proposals, included:

  • Samsung and Sony
  • Canada’s Communications Research Centre and South Korea’s Electronics and Telecommunications Research Institute
  • Qualcomm and Ericsson
  • LG, Zenith and Harris Broadcast
  • China’s National Engineering Research Center of Digital Television, Shanghai Jiao Tong University, Shanghai Advance Research Institute, Chinese Academy of Sciences and Bell Labs
  • Allen Limberg
  • Technicolor
  • Power Broadcasting

Peter Siebert, executive director of DVB, told TVNewsCheck that his standards organization planned on submitting a proposal for ATSC 3.0, and was confident that the finalized standard will be based around or derived from DVB’s technology.

LG: Consumers Still Want 3D Experiences

LG: Consumers Still Want 3D Experiences

ESPN’s move to shut down its 3D channel at the end of the year tells us consumers just aren’t ready for eye-popping, live sporting events.

So what are TV manufacturers saying? 3D isn’t being as heavily marketed today as it was, say, three years ago, but one TV manufacturer believes it still has a role in the household, specifically for watching movies.

John Taylor, spokesman for LG Electronics USA, said the company still sees 3D as a “terrific feature that delivers a great consumer experience.”

Taylor pointed to the company’s LG Cinema 3D technology, which requires the same polarized eyewear you find in movie theaters. He calls it the fastest growing approach to 3D in the home, adding that ESPN’s announcement was just a minor setback.

“While ESPN 3D will be missed, there are growing amounts of 3D content available via other channels, including Blue-ray discs, online content and through the 3D World application on LG Cinema 3D Smart TVs, which provide instant access to a wide range of 3D content, including Disney’s 3D movie library,” Taylor said. “What’s more, our 2D-to-3D converter brings the 3D experience to virtually any content, including sports and video games.

“Consumers will continue to look for the technology that allows them to recreate that experience at home, and LG is pleased to be able to deliver that.”

Analysts that cover this space aren’t as optimistic.

“The ESPN decision is a sign that the 3D ecosystem is not healthy,” Laura Martin, an analyst with investment banking firm Needham & Co., told the Associated Press. “It must be there’s not enough demand for 3D TV.”

Will 3D ever play a role in live television? What about over-the-air broadcast television? Weigh in below.
