ATSC 3.0

ATSC 3.0 (branded as NEXTGEN TV in the United States)[1] is a major version of the ATSC standards for television broadcasting created by the Advanced Television Systems Committee (ATSC).[2][3][4]

The standards are designed to offer support for newer technologies, including HEVC for video channels of up to 2160p 4K resolution at 120 frames per second, wide color gamut, high dynamic range, Dolby AC-4 and MPEG-H 3D Audio, datacasting capabilities, and more robust mobile television support.[2][5] The capabilities have also been foreseen as a way to enable finer public alerting and targeted advertising.

The first major deployments of ATSC 3.0 occurred in South Korea in May 2017, in preparation for the 2018 Winter Olympics. In November 2017, the FCC approved the voluntary use of ATSC 3.0 for television broadcasting in the United States; there will not be a mandatory transition as there was from analog NTSC to ATSC, and full-power stations that convert must preserve the availability of their programming in their city of license via legacy ATSC signals. In December 2021, Jamaica adopted ATSC 3.0 for its impending transition from analog to digital television, with Television Jamaica launching ATSC 3.0 service the following month.
