Ultrahigh-definition television (UHDTV) is a wide-color-gamut system, as standardized in Rec. ITU-R BT. 2020 and SMPTE ST 2036-1, that covers most real object colors and encompasses the gamuts of high-definition television (HDTV), Adobe RGB, and Digital Cinema Initiative Primary 3 (DCI-P3). The development of wide-gamut displays and high-quality gamut mapping is a major challenge in the workflow of UHDTV production today. While monochromatic light sources, such as lasers, are ideal for UHDTV wide-gamut displays, wide-gamut liquid crystal displays with nonmonochromatic backlight sources, such as quantum dot light-emitting diodes, 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.
