HDR Demystified: Emerging UHDTV Systems

By Thomas Schulte and Joel Barsotti

The new Ultra High Definition TV (UHDTV) system, which the CE industry is currently migrating to from HDTV, will benefit greatly from Higher Dynamic Range (HDR) and Wide Color Gamut (WCG).These enhanced features have been received very positively by consumers. CE manufacturers are moving very quickly to introduce equipment to the market with various levels of UHD capability. This fast movement in the industry has left many confused about UHDTV capabilities, proposed system features, system compatibility, and standards.This preliminary draft document attempts to shed light on High Dynamic Range and Wide Color Gamut, the two significant features of UHDTV that will affect how the image accuracy of these new generation TVs is tested and calibrated.We cover the different industry proposals related to HDR and WCG and we briefly discuss how CalMAN display calibration software addresses these new technologies. About the authors: Tom Schulte is Product Development Manager at SpectraCal. Tom has extensive experience in electronic systems test, calibration and service, as well as electronics test instrument design and usage and has authored numerous technical white papers. Tom was previously an Application Engineer at Sencore for over twenty years, where he was involved in video, audio, and RF test instrument design, plus training and support for electronic test equipment users. Joel Barsotti is Head of Advanced Color Research at SpectraCal. He has been the primary architect of every version of CalMAN since version 4.0. Joel has designed several iterations of 3D LUT profiling code, each of which has significantly advanced the state of the art. His innovations include: CalMAN AutoCube technology, CalMAN Dynamic Profiling process, Dynamic Linearity Correction, Intelligent Resolution Profiling, Lightning LUT, 3D LUT Retargeting, the adaptation of volumetric interpolation to color science, grayscale priority interpolation, and grayscale tint reduction, making CalMAN one of the most sophisticated color management packages available.
