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 ...
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. It was revised in 2009.
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.

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.
As a result, ATSC 3.0 will be incompatible with all current ATSC 1.0 receivers, and viewers will need a new TV with a compatible tuner or a converter box. [5] Unlike the previous digital TV transition which was mandated by the FCC, the "transition" to ATSC 3.0 will be completely voluntary.
On November 17, 2017, the FCC voted 3-2 in favor of authorizing voluntary deployments of ATSC 3.0, which was designed as the successor to the original ATSC "1.0", and issued a Report and Order to that effect. 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 ...
When tested for ATSC 3.0 the bit rates needed for the required audio score was 96 kbit/s for stereo audio, 192 kbit/s for 5.1 channel audio, and 288 kbit/s for 7.1.4 channel audio. [1] However, for 22.2 channel audio, the required bit rate may be as high as 1536 kbit/s. [7]
