Conversion and coding practices for HDR/WCG Y'CbCr 4:2:0 video with PQ transfer characteristics
This document provides guidance on the processing of High Dynamic Range (HDR) and Wide Colour Gamut (WCG) video content. The purpose of this document is to provide a set of publicly referenceable recommended guidelines for the operation of AVC or HEVC video coding systems adapted for compressing HDR/WCG video for consumer distribution applications. This document includes a description of processing steps for converting from 4:4:4 RGB linear light representation video signals into non-constant luminance (NCL) Y¢CbCr video signals that use the Perceptual Quantizer (PQ) transfer function defined in SMPTE ST 2084 and Rec. ITU-R BT.2100. Although the focus of this document is primarily on 4:2:0 Y¢CbCr 10 bit representations, these guidelines may also apply to other representations with higher bit depth or other colour formats, such as 4:4:4 Y¢CbCr 12 bit video. In addition, this document provides some high-level recommendations for compressing these signals using either the AVC or HEVC video coding standards. A description of post-decoding processing steps is also included for converting these NCL Y¢CbCr signals back to a linear light, 4:4:4 RGB representation.

This Supplement was jointly developed by ITU-T Study Group 16 and ISO/IEC JTC1 SC29/WG11 and may be found as ISO/IEC TR 23008-14 "Information technology – High efficiency coding and media delivery in heterogeneous environments – Part 14: Conversion and coding practices for HDR/WCG Y'CbCr 4:2:0 video with PQ transfer characteristics".
