UHDTV is a wide-color-gamut system, as standardized in Recommendation ITU-R BT.2020 and SMPTE ST 2036-1, that covers most real object colors and encompasses the gamuts of HDTV, Adobe, and DCI-P3. The development of wide-gamut displays and high-quality gamut mapping are major challenges in the workflow of UHDTV production today. While monochromatic light sources, such as lasers, are ideal for UHDTV wide-gamut displays, wide-gamut LCDs with non-monochromatic backlight sources, such as quantum dot LEDs, may well be used from the viewpoint of both cost and performance. Furthermore, a high-quality gamut mapping algorithm between UHDTV and HDTV for live broadcast production is essential. This paper offers solutions to these challenges.
