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 ...
SDR video with a conventional gamma curve and a bit depth of 8-bits per sample has a dynamic range of about 6 stops, assuming a luminance quantisation threshold of 5% is used. [10] A threshold of 5% is used in the paper (instead of the standard 2% threshold) to allow for the typical display being dimmer than ideal.
SDR, HDR, and WDR are camera terms that refer to what type of imaging tech your device uses to capture details in over- and under-exposed lighting environments.
Rec. 2100 is an ITU-R Recommendation released in July 2016 that defines high dynamic range (HDR) formats for both HDTV 1080p and 4K/8K UHDTV resolutions. [56] These formats use the same color primaries as Rec. 2020, but with different transfer functions for HDR use. Rec. 2100 does not support the YcCbcCrc scheme of Rec. 2020.
Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
HDR video refers to a video encoded in an HDR format. Thoses HDR video have a greater bit depth, luminance and color volume than standard dynamic range (SDR) video which uses a conventional gamma curve. [22] On January 4, 2016, the Ultra HD Alliance announced their certification requirements for an HDR display.
Technical limitations in distributing 4K broadcasts (including the increased cost of 4K-compatible production equipment) [126] have led to some broadcasters deciding against the format in favour of emphasizing 1080p/HDR broadcasts instead.
Rec. 2100, a standard for high-dynamic-range television (HDR-TV) with FHD and UHD resolution sRGB , a standard color space for web/computer graphics, based on the Rec. 709 primaries and white point References
