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.
As of 2020, no display is capable of rendering the full range of brightness and color of HDR formats. [28] A display is called an HDR display if it can accept HDR content and map it to its display characteristics, [28] so the HDR logo only provides information about content compatibility and not display capability.
Logo. HDR10+ [1] is a high dynamic range (HDR) video technology that adds dynamic metadata [2] to HDR10 source files. The dynamic metadata are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way based on the content creator's intentions.
The number of devices certified for HDR10+ support grew just a bit more, now that Chromecast with Google TV and new Roku devices have joined the list.
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 displays refers to displays compatible with that technology. HDR formats refers to formats such as HDR10, HDR10+, Dolby Vision and HLG. 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]
[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. [12] [13] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR), while HLG is compatible.
