Dynamic Metadata for Color Volume Transform - Application #5

Metadata

Publisher: SMPTE
Suite/Collection: Dynamic Metadata for Color Volume Transform
Doc Type: Standard (ST)
Abstract: This standard specifies the metadata for the Color Volume Transform Application #5. It is a specialization of the content-dependent transform metadata entries and processing blocks of the generalized color volume transform model defined in SMPTE ST 2094-1:2016.

It includes parameters for conversion of an input image essence to a common relative linear color space, parameters for a headroom-adaptive tone mapping algorithm, and the mathematical definition of that headroom-adaptive tone mapping algorithm.
