Dolby Vision

Dolby Vision is an HDR format developed by Dolby Laboratories that extends the dynamic range and color depth of 4K video. The signal is encoded up to 12 bits per component in the BT.2020 color space, with a theoretical peak luminance reaching 10,000 nits.

The distinguishing feature of Dolby Vision lies in its dynamic metadata transmitted scene by scene, or even frame by frame. The television or video projector applies adaptive tone mapping calibrated to its own luminance and gamut capabilities, rather than a static curve set for the entire program. The stream includes a basic HDR10 layer, which guarantees backward compatibility with devices that do not decode Dolby Vision.
