Cleveland, Ohio –– The journey to over-the-air UHD TV, mobile TV and emergency data services accelerated last week with a series of high-power broadcast tests conducted here. Attending the ATSC 3.0 Futurecast demos were six-dozen TV engineers, TV receiver makers, programmers and network operators navigating huge transmitter modulation engineering options in a quest to revolutionize free over-the-air TV delivery.

The demonstration tour was sponsored by LG Electronics, LG’s Zenith Electronics division, transmitter maker GatesAir and the Advanced Television Systems Committee. ATSC is headed towards a key member vote to approve common technologies necessary for ATSC 3.0 candidate voting ratification. The Cleveland tests were designed to bullet-proof the demonstration showing how the LG/GatesAir Futurecast systems work using traditional TV transmitters; operating over a period of many weeks and months.

Propelling signals with more than 30 percent more data content than today’s ATSC 1.0 system into the air was WJW-TV, a Fox affiliate which rallied to revive a dormant channel 31 TV transmitter to demonstrate Futurecast with a digital carousel of programming. UHD TV - using HEVC codec compression to sixteen megabits a second, HDTV, SDTV along with emergency signals and data tests.

ATSC members will soon vote on elements of the Futurecast architecture. Key technology benefits cited include:

Data throughput increases of 30 percent and improved multipath performance (compared with the current DTV standard) for fixed and portable TV reception;

Enhanced indoor TV signal penetration for mobile reception thanks to flexible system parameter choices;

Advanced modes for delivery of very high data rates and very robust transmission capabilities;

State-of-the-art error correction coding and signal constellations;

Future Extension Frames to support evolution of future broadcast systems; and,

Improved single frequency network service.

“Our technology is designed to fully meet broadcaster requirements for ATSC 3.0 and advance the goal of moving rapidly to next-generation broadcasting. Whether watching from deep inside a building or along the Lake Erie lakefront, field test results show that our ATSC 3.0-enabling technology performs exactly as expected,” said Dr. Skott Ahn, President and Chief Technology Officer, LG Electronics in a statement.

As the FCC seeks to pack broadcasters into less and less bandwidth the new ATSC 3.0 standard will become crucial to the future success of local broadcasting. Higher bit rates and improved codeces mean better picture quality and/or more channels using the same bandwidth.
