Title: COLOR VOLUME TRANSFORMS IN CODING OF HIGH DYNAMIC RANGE AND WIDE COLOR GAMUT SEQUENCES
Abstract:
A method of encoding a digital video, comprising receiving a high dynamic range (HDR) master of a video, a reference standard dynamic range (SDR) master of the video, and target SDR display properties at an encoder, finding a color volume transform that converts HDR values from the HDR master into SDR values that, when converted for display on the target SDR display, are substantially similar to SDR values in the reference SDR master, converting HDR values from the HDR master into SDR values using the color volume transform, generating metadata items that identifies the color volume transform to decoders, and encoding the SDR values into a bitstream.
