- Abstract
- 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.

bio
Kenichiro Masaoka received a B.S. in electronics engineering and an M.S. in energy engineering from the Tokyo Institute of Technology, Tokyo, Japan. He joined Japan Broadcasting Corp. (NHK) in 1996. He is principal research engineer for the Advanced Television Systems Research Division, NHK Science & Technology Research Laboratories (STRL), Tokyo. He received a Ph.D. in engineering from the Tokyo Institute of Technology in 2009. His research interests include color science, human vision, and digital imaging systems. He is a member of the Institute of Electrical and Electronics Engineers (IEEE), SMPTE, and the Institute of Image Information and Television Engineers of Japan (ITE).Takayuki Yamashitabio
Takayuki Yamashita is senior research engineer for the Advanced Television Systems Research Division of NHK Science & Technology Research Laboratories (STRL). He is working on the research of UHDTV systems and his research fields include the development of camera systems, image sensors, and high-bandwidth digital signal processing and transmission systems. He also has an interest in the research of capturing system for next-generation 3DTV. Yamashita joined NHK in 1995 after receiving B.E. and M.E. degrees in electronic engineering and information science from Kyoto Institute of Technology, Kyoto, Japan, in 1993 and 1995, respectively. He has been engaged in research of HDTV camera systems since 1999. He is a member of SMPTE and ITE and is also active in the standardization of broadcast technologies in the Association of Radio Industries and Businesses (ARIB).Yukihiro Nishidabio
Yukihiro Nishida is senior research engineer for the Advanced Television Systems Research Division of NHK STRL. He has been involved in many areas of broadcasting technologies, including HDTV, digital broadcasting, video coding, multiplexing, quality evaluation, and UHDTV. He is also active in the standardization of broadcast technologies in ITU-R and the ARIB. He is vice-chair of the ITU-R Study Group 6 on Broadcasting Services, and is also chair of Working Party 6B. Nishida received B.S. and M.S. degrees in electric engineering from Keio University, Yokohama, Japan, and a Ph.D. in engineering from the University of Electro-Communications, Tokyo, Japan.Masayuki Sugawarabio
Masayuki Sugawara received B.S. and M.S. degrees in electric communication engineering and a Ph.D. degree in electronic engineering from Tohoku University, Sendai, Japan. He joined NHK in 1983. Since 1987, he has been researching solid-state image sensor, HDTV camera, and the UHDTV system at NHK STRL. Sugawara was an associate professor at the University of Electro-Communications, Tokyo, Japan, from 2000 to 2004. He has been attending ITU-R SG6 meetings since 2004 and has been active in the working parties that address program production. Currently, he is deputy director of NHK STRL. Sugawara is a member of IEEE, SMPTE, the Institute of Electronics, Information and Communication Engineers (IEICE), and ITE. - Keyword(s)
