A landmark broadcast from Las Vegas TV station KHMP-TV’s GatesAir transmitter on Nevada’s Black Mountain is broadcasting pristine 4K HDR content, received for the first time at the Las Vegas Convention Center on LG’s new ATSC 3.0-enabled receivers. The signal has stunning detail with four times the resolution of today’s HDTV and offers the lifelike realism of HDR’s enhanced contrast, brightness and shadow detail.

DNV Spectrum Holdings, a broadcast group that also owns other stations in the United States owns and operates KHMP Channel 18. KHMP is broadcasting the ATSC 3.0 Physical Layer Candidate Standard under an experimental broadcast license from the Federal Communications Commission (FCC).

Core technologies developed by LG are included in the majority of the Physical Layer Candidate Standard. The transmission field trial during CES exemplifies the very robust transmission and high bandwidth for 4K made possible for the first time using the ATSC 3.0 next-generation standard developed by the Advanced Television Systems Committee.

“We are proud that LG technology is behind the majority of the elements of the Physical Layer transmission system,” said Dr. Skott Ahn, president and chief technology officer, LG Electronics. “ATSC 3.0 is a collaborative effort among many broadcast technology experts, and LG technology is part of at least 10 of the 15 building blocks of the new Candidate Standard.” Among the many LG contributions to ATSC 3.0, the company’s technologies are included in the Physical Layer Candidate Standard’s scrambler, forward error correction, bit-interleaver, mapper, MIMO, time-interleaver, OFDM framer, frequency-interleaver, pilot and tone reserve, and guard interval.

Expected to redefine TV broadcasting for decades to come, the ATSC 3.0 next-generation broadcast standard provides higher capacity to deliver 4K UHD services, robust reception on mobile devices and improved spectrum efficiency. The increased payload capacity of the physical layer combined with HEVC encoding will allow broadcasters many more options when planning their broadcast service offerings.

“LG is leading the way in development and commercialization of ATSC 3.0 in the U.S. and in Korea,” said Ahn, who explained that this week’s Las Vegas broadcast comes on the heels of other broadcast field trials conducted in the United States and South Korea over the past 18 months by LG Electronics, its U.S. R&D Lab Zenith, and leading broadcast equipment provider GatesAir.

Those real-world field tests in Seoul, Cleveland, Ohio, Madison and Wisconsin, represented key mileposts in LG’s pioneering developments of core technologies behind the new ATSC 3.0 Standard, he said. “The Las Vegas CES broadcast, with the approved ATSC Candidate Standard transmission system, again shows how we are partnering with broadcasters around the world to drive adoption of next-generation broadcasting technology.”

Development of ATSC 3.0 technologies represents the latest collaboration among LG, Zenith and GatesAir, co-inventors of the transmission system behind the ATSC A/153 Mobile Digital TV Standard, adopted by the industry in 2009. Zenith invented the core transmission system at the heart of today’s ATSC A/53 Digital Television Standard, approved by the Federal Communications Commission in 1996.

A similar demonstration without HDR is also being conducted at CES 2016 by Samsung, Comark and TeamCast.
