SMPTE ST 2094-20:2016

This standard specifies the content-dependent Color Volume Transform metadata set for Application #2, a specialized model of the color volume transform defined by the core components document SMPTE ST 2094-1.

The Color Volume Transform is based on a tone mapping curve that operates on image data in a perceptually-uniform domain and a luminance-dependent saturation gain curve. Both the tone mapping curve and the saturation gain curve are fully characterized by a set of parameters.
