The Advanced Television Systems Committee (ATSC) is an international, nonprofit organization developing technical standards for digital terrestrial television and data broadcasting. ATSC's 120-plus member organizations represent the broadcast, broadcast equipment, motion picture, consumer electronics, computer, cable, satellite and semiconductor industries.

ATSC was initially formed in 1983 to develop a first-generation digital television standard that could replace existing analog transmission systems. The new digital system became known as "ATSC 1.0." ATSC 1.0 is in use in the United States, Canada, Mexico, South Korea and Honduras and also in the Dominican Republic.

ATSC then developed a next-generation digital television standard known as "ATSC 3.0.” ATSC 3.0 was commercially deployed in South Korea in May 2017[1] and was approved for voluntary use in the United States in November 2017.[2]

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

Transcription

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.
