HDR10+, also known as HDR10 Plus, was announced on 20 April 2017, by Samsung and Amazon Video. HDR10+ updates HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to the full range of PQ code values (10,000 nits maximum brightness) on a scene-by-scene or frame-by-frame basis.
HDR10+, also known as HDR10 Plus, is an HDR video format announced on 20 April 2017. [21] It is the same as HDR10 but with the addition of a system of dynamic metadata developed by Samsung. [22] [23] [24] It is free to use for content creators and has a maximum $10,000 annual license for some manufacturers. [25]
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.
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.
High-dynamic-range formats for image and video files are able to store more dynamic range than traditional 8-bit gamma formats. These formats include: HDR formats that can be used for both storage and transmission to HDR displays, such as: For video: HDR10; HDR10+ Dolby Vision; HLG (backwards compatible with SDR displays) For images:
The device supports 4K resolution output at 60 FPS over an HDMI 2.0 output, with support for HEVC-encoded video. The Shield can either contain 16 GB of internal flash storage or a 500 GB hard drive, expandable via microSD card or removable storage. 2015 and 2017 Shield models with a 500 GB hard drive are branded as Shield Pro .
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. [12] [13] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR), while HLG is compatible. Chart showing the PQ electro-optical transfer function.
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 ...
