This paper presents a state of the art approach in HDR/WCG video coding developed at FastVDO called FVHDR, and based on the JEM 6 Test Model of the Joint Exploration Team, a joint committee of ITU|ISO/IEC. A fully automatic adaptive video process that differs from a known HDR video processing chain (analogous to HDR10, herein called “anchor”) developed recently in the standards committee JVET, is used. FVHDR works entirely within the framework of JEM software model, but adds additional tools. These tools can become an integral part of a future video coding standard, or be extracted as additional pre- and post-processing chains. Reconstructed video sequences using FVHDR show a subjective visual quality superior to the output of the anchor. Moreover the resultant SDR content generated by the data adaptive grading process is backward compatible. Representative objective results for the system include: results for DE100, and PSNRL100, were -13.4%, and -3.8% respectively.
