Abstract

High Dynamic Range and Wide Color Gamut (HDR/WCG) video is now at the forefront of modern broadcast and other video delivery systems. The efficient transmission and display of such video over diverse networks and systems is an important problem. This paper presents a novel, state of the art approach in HDR/WCG video coding (called FV10) which uses a new, fully automatic video data adaptive regrading process, which converts HDR to Standard Dynamic Range (SDR). Our method differs from one developed recently in standards committees (the Joint Collaborative Team on Video Coding, or JCT-VC, of ITU|ISO/IEC), based on the HEVC Main10 Profile as the core codec, which is an HDR10 compliant system (“anchor”). FV10 also works entirely within the framework of HEVC Main10 Profile, but makes greater use of existing SEI messages. Reconstructed video using our methods show a subjective visual quality superior to the output of an example HDR10 anchor. Moreover, a usable backwards compatible SDR video is obtained as a byproduct in the processing chain, allowing service efficiencies. Representative objective results for the system include: results for RGB-PSNR, DE100, MD100, tOSNR-XYZ were -46.0%, -21.6%, -29.6%, 16.2% respectively.
