FUTURECAST™ Next-Gen TV Broadcast System: GatesAir’s ATSC 3.0 Collaboration with LG and Zenith

The move to a next-generation advanced TV broadcasting system
includes a basic requirement: advanced compression technology
that will it make possible to deliver both ultra high definition TV and mobile TV streams
to future viewers. The fundamental requirement
for a next-generation standard is a strong physical layer for ATSC 3.0 that will carry this payload through
the broadcast transmitter to the receiver. In the future, viewers
could be watching live TV on a curved-screen
Ultra HDTV in the living room or on a tiny mobile device
equipped to receive live broadcast TV in any remote location. Developed by LG Electronics, its Zenith R&D subsidiary, and GatesAir, the Futurecast universal
terrestrial broadcasting system is designed to deliver a
diverse mix of services to viewers within the same 6 megahertz channel
used today for ATSC 1.0. Testing at various sites
in Madison, Wisconsin, through the facilities of
Quincy Group’s WKOW-TV, shows that Futurecast allows deep indoor reception for mobile devices and also 4k Ultra HDTV for the home. In fact, Futurecast
has been shown to deliver 4k Ultra HD content and two robust mobile TV streams
in a single channel. Nearly 50,000 pieces of data
from scores of reception sites were recorded during the tests, including challenging reception
areas inside buildings, in fast-moving vehicles, and locations from downtown to 50 miles from the transmitter. Futurecast is designed to both
increase data throughput by 30% and improve multi-path performance for fixed and portable TV reception. It can enable energy-saving
features for consumer receivers, and it can be adjusted to deliver
content at very high data rates, very robust transmission,
or numerous combinations. Futurecast also utilizes HEVC
advanced video compression, which efficiently supports video formats ranging from 4k UHDTV to lower resolutions intended
for very small screen devices. The increased payload
capacity of the physical layer, combined with HEVC encoding, will allow broadcasters
many more options when planning their
broadcast service offering. The Futurecast system is designed
to fully meet broadcasters’ requirements for the ATSC 3.0 physical layer and advances the goal
of moving rapidly to next-gen broadcasting. In short, Futurecast is
the ideal, complete solution for the ATSC 3.0 physical layer.
