ATSC 3.0 is a major version of the ATSC standards for terrestrial television broadcasting created by the Advanced Television Systems Committee (ATSC). [1] [2] [3]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 ...
An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner, is a type of television tuner that allows reception of digital television (DTV) television channels that use ATSC standards, as transmitted by television stations in North America (including parts of Central America) and South Korea.
A separate tuner is required to receive HD satellite broadcasts. Cable television companies in the U.S. generally prefer to use 256-QAM to transmit HDTV. Many of the newer HDTVs with integrated digital tuners include support for decoding 256-QAM in addition to 8VSB for OTA digital. Cable television companies started carrying HDTV in 2003.
Argentina seemed to be settling on the ATSC standard before 2009, and Uruguayan URSEC authorities have provided no information on which road they will go. On August 27, 2007, URSEC settled on DVB-T and DVB-H. The TV sets being sold in Uruguay seem to be closer to ATSC HDTV-based standards (60 Hz systems, with ATSC tuners in some cases).
Transition to ATSC 3.0 is voluntary on both ends: television manufacturers are not required to provide ATSC 3.0 compatible tuners in televisions. Further, digital television stations may elect to broadcast in ATSC 3.0 at any time, with the caveat that they must simulcast ATSC 1.0 signals for up to five years after beginning broadcasts in ATSC 3.0.
ATSC was initially formed in 1982 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 3.0 is a non-backwards-compatible version of ATSC being developed (as of May 18, 2016) that uses OFDM instead of 8VSB and a much newer video codec (instead of ATSC 1 and 2's MPEG-2). On March 28, 2016, the Bootstrap component of ATSC 3.0 (System Discovery and Signalling) was upgraded from candidate standard to finalized standard.
