HIGH DYNAMIC RANGE ADAPTATION OPERATIONS AT A VIDEO DECODER

摘要

A method of decoding a bitstream (108) comprises decoding the bitstream into color values and metadata items indicating information about adaptive post-processing operations performed by a decoder (302), performing high dynamic range (HDR) adaptation operations on the color values based on the metadata items (308), and performing fixed post-processing operations to reconstruct an HDR video from the color values (312), wherein the HDR adaptation operations convert color values into a format expected by the fixed post-processing operations.
