Dolby Vision

Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. 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 was introduced in 2014, making it the first available HDR format. HDR10+ is a competitor HDR format that also uses dynamic metadata.

Dolby Vision IQ is an update designed to optimize Dolby Vision content according to the ambient light.

Dolby Cinema uses Dolby Vision too, though because of the use of 2.6 gamma and thus 48 nits in SDR cinemas, the 108 nits used in Dolby Cinema is already HDR.
