UHD Phase A is a set of guidelines from the Ultra HD Forum for the distribution of SDR and HDR content using Full HD 1080p and 4K UHD resolutions. It requires a color depth of 10 bits per sample, a color gamut of Rec. 709 or Rec. 2020, a frame rate of up to 60 fps, a display resolution of 1080p or 2160p and either standard dynamic range (SDR ...
On January 4, 2016, the Ultra HD Alliance announced their certification requirements for an HDR display. [ 23 ] [ 24 ] The HDR display must have either a peak brightness of over 1000 cd/m 2 and a black level less than 0.05 cd/m 2 (a contrast ratio of at least 20,000:1) or a peak brightness of over 540 cd/m 2 and a black level less than 0.0005 ...
Rec. 709 defines the color space for HDTV, and Rec. 2020 defines a larger but still incomplete color space for ultra-high-definition television. Since the 2010s, OLED and other HDR display technologies have reduced or eliminated the need for tone mapping HDRR to standard dynamic range.
Typically less than 0.01 ms, as low as 2 μs, [10] [14] but limited by phosphor decay time (around 5 ms) Estimates varying from under 0.01 ms to as low as 1 μs. [15] [16] Frame rate (refresh rate) 60–85 fps typically, some CRTs can go even higher (200 fps at reduced resolution [17]); internally, display refreshed at input frame rate speed
FHD (Full HD) is the resolution 1920 × 1080 used by the 1080p and 1080i HDTV video formats. It has a 16:9 aspect ratio and 2,073,600 total pixels, i.e. very close to 2 megapixels, and is exactly 50% larger than 720p HD (1280 × 720) in each dimension for a total of 2.25 times as many
It defines various aspects of HDR-TV such as display resolution (HDTV and UHDTV), frame rate, chroma subsampling, bit depth, color space, color primaries, white point, and transfer function. [3] [4] It was posted on the International Telecommunication Union (ITU) website on July 4, 2016.
HDR10 Media Profile, more commonly known as HDR10, is an open high-dynamic-range video (HDR) standard announced on August 27, 2015, by the Consumer Electronics Association. [1] It is the most widespread HDR format. [2] HDR10 is not backward compatible with SDR. It includes HDR static metadata but not dynamic metadata.
