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.
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.
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.
Unlike standard set-top box (or set-top unit) appliances, HDHomeRun does not have a video output that connects directly to the user's television. It instead receives a live TV signal and then streams the decoded video over a local area network to an existing smart phone, tablet computer, smart tv, set top streaming device, computer, or game console.
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.
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. [1]
This was in order to work out any kinks which may not be foreseen before most of the country's broadcasters stopped transmitting traditional analog signals and upgrade to digital-only programming. Full-power terrestrial broadcasts using the analog NTSC standard was required by law to cease by June 12, 2009. [ 88 ]
