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.
Dolby Vision is an end-to-end ecosystem for HDR video, and covers content creation, distribution, and playback. [20] It uses dynamic metadata and is capable of representing luminance levels of up to 10,000 nits. [6] Dolby Vision certification requires displays for content creators to have a peak luminance of at least 1,000 nits. [8]
HDR10+ is an alternative to Dolby Vision, which also uses dynamic metadata. [3] HDR10+ is the default variant of dynamic metadata as part of the HDMI 2.1 standard. [4] HDR10+ Adaptive is an update designed to optimize HDR10+ content according to the ambient light. [5]
It was developed by Dolby [6] and standardized in 2014 by SMPTE [1] and also in 2016 by ITU in Rec. 2100. [7] [8] ITU specifies the use of PQ or HLG as transfer functions for HDR-TV. [7] PQ is the basis of HDR video formats (such as Dolby Vision, [2] [9] HDR10 [10] and HDR10+ [11]) and is also used for HDR still picture formats.
For narrow range color, 10-bit per sample signals use video levels where the black level is defined as 64, achromatic gray level as 512 and the nominal peak as 940 in RGB, Y, and I encoding and 960 in Cb/Cr, and Ct/Cp component encoding. 12-bit per sample signals define 256 as the black level, 2048 as the gray level and the nominal peak is 3760 ...
It also provides up to 8K resolution and color depth of up to 12-bits (backwards compatible with current 8-bit and 10-bit displays). [39] Dolby Vision can encode mastering display colorimetry information using static metadata (SMPTE ST 2086) and dynamic metadata (SMPTE ST 2094-10, Dolby format) for each scene or frame of a video.
