[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 ...
ATSC standards are marked A/x (x is the standard number) and can be downloaded for free from the ATSC's website at ATSC.org. ATSC Standard A/53, which implemented the system developed by the Grand Alliance, was published in 1995; the standard was adopted by the Federal Communications Commission in the United States in 1996.

Full-power stations will be required to maintain a simulcast of their channels on an ATSC 1.0-compatible signal if they decide to deploy ...
ATSC and 8VSB modulation is used primarily in North America; in contrast, the DVB-T standard uses COFDM. A modulation method specifies how the radio signal fluctuates to convey information. ATSC and DVB-T specify the modulation used for over-the-air digital television; by comparison, QAM is the modulation method used for cable. The ...
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.
Mobile DTV is also carried on ATSC stations, but as a separate service, according to the ATSC-M/H standard. The Federal Communications Commission (FCC) considers all subchannels carried by a single station to have the same call letters for legal identification purposes. However, within the broadcast sales industry, to differentiate subchannels ...
