ATSC 3.0

ATSC 3.0 is a major version of the <a href="/facts/ATSC_standards/RIYWmB7v">ATSC standards</a> for terrestrial <a href="/facts/Broadcast_television_systems/BT0FfFcy">television broadcasting</a> created by the <a href="/facts/Advanced_Television_Systems_Committee/JhzeErLa">Advanced Television Systems Committee</a> (ATSC). 
The standards are designed to offer support for newer technologies, including <a href="/facts/High_Efficiency_Video_Coding/6gp7DC1a">High Efficiency Video Coding</a> (HEVC) for video channels of up to <a href="/facts/4K_resolution/Ehhhg0rD">4K resolution</a> (2160p) at <a href="/facts/High_frame_rate/BJHr2yLN">120 frames per second</a>, <a href="/facts/Wide_color_gamut/bRQc2fCr">wide color gamut</a>, <a href="/facts/High-dynamic-range_video/jzRH1mFe">high dynamic range</a>, <a href="/facts/Dolby_AC-4/FXj0MW2d">Dolby AC-4</a> and <a href="/facts/MPEG-H_3D_Audio/tPvIwD8f">MPEG-H 3D Audio</a>, <a href="/facts/Datacasting/vfdxz1XJ">datacasting</a> capabilities, and more robust <a href="/facts/Mobile_television/N06lgVtM">mobile television</a> support. The capabilities have also been foreseen as a way to enable finer <a href="/facts/Emergency_population_warning/EUEy5JU0">public alerting</a> and <a href="/facts/Targeted_advertising/SsSEgQlt">targeted advertising</a>.
The first major deployment of ATSC 3.0 occurred in <a href="/facts/South_Korea/pCobAaVw">South Korea</a> in May 2017, in preparation for the <a href="/facts/2018_Winter_Olympics/AgjfEafm">2018 Winter Olympics</a>. In November 2017, the <a href="/facts/Federal_Communications_Commission/Ueghz8W0">FCC</a> passed rules allowing American broadcast stations to voluntarily adopt ATSC 3.0 ("Next Gen TV"), provided that full-power stations preserve the availability of their programming in their <a href="/facts/City_of_license/SPId6NJv">city of license</a> via legacy ATSC signals; adoption is being steered by the broadcasting industry, without a mandatory transition as there was <a href="/facts/Digital_television_transition_in_the_United_States/fbs2Tp7z">from analog NTSC to ATSC</a>. Other adoptions have since occurred in <a href="/facts/Jamaica/jeDulmwE">Jamaica</a> and <a href="/facts/Trinidad_and_Tobago/jTXQP4Fe">Trinidad and Tobago</a> (which are both transitioning from analog television), while <a href="/facts/Brazil/QHkG46GL">Brazil</a> has proposed a transition from <a href="/facts/ISDB-T_International/6FDcvU0N">ISDB-T International</a> to standards derived from ATSC 3.0.
