Abstract: The introduction of high-efficiency light sources such as LEDs in TV and film production studios has revitalized the earlier work of W. N. Sproson, and E. W. Taylor (BBC) on the effects of lighting for television. In the report of this work at IBC2011, Alan Roberts gave a well-informed look into what may well be the consequences of uncritically introducing LED-based studio lighting into program production. In order to fully realize the proposed Television Lighting Consistency Index (TLCI-2012), it is necessary to have information about the spectral sensitivity in modern TV cameras using CCD and CMOS sensors. Since camera manufacturers are reluctant to disclose such information, work has been undertaken at the Norwegian Broadcasting Corp. (NRK) to measure the spectral sensitivity properties of modern HDTV cameras. The result of this work has enabled the authors to develop the proposal for a “standard” television camera color model that is presented in this paper.

bio
Per Böhler has been with the Norwegian Broadcasting Corp. (NRK) since 1963. After graduating from the NRK Engineering School he worked for a few years as an operational engineer. In the remaining years he has worked in the engineering development/technology departments. His professional work has entirely been dedicated to video origination equipment, video processing/recording/compression/display technologies and optical testing of camera lenses for both film and TV cameras. — Böhler has been actively involved in the European Broadcasting Union (EBU) since 1982 until present. He has chaired several EBU project groups and co-chaired/chaired the EBU Production Technology Management Committee (PMC) for 16 years. He is currently Chair of the EBU FTV (Future TeleVision)-LED project and of the EBU Expert Community for Video (EC-V).
John Emmett
bio
John Emmett joined the engineering department of Thames Television in London after gaining a Ph.D. at Durham University, and starting the U.K. audio equipment manufacturers EMO Systems Ltd. While at Thames Television, he worked on subjects as diverse as film archive formats and psychoacoustics, and gained six international patents as sole inventor, and jointly with Lee Lighting, a Technical Oscar for developing the flicker-free Lighting Ballast. — Emmett continued as R&D manager at Pearson Television, and is currently technical director and chief executive of Broadcast Project Research, an independent studio-based research group. Originally representing the U.K. as principal digital audio expert to the IEC, he is well-known for his work on digital audio and video standards. Until recently, he chaired the EBU digital audio advisory group P/AGA, which was responsible for the Broadcast Wave Format.
Alan Roberts
bio
Alan Roberts joined the BBC's R&D department in 1968 as a research engineer and worked on a wide variety of projects, including standards conversion, teletext, digital video processing, and surface-wave device fabrication, before specializing in color science and production technology. — Roberts was part of the team that worked on the Eureka95 HDTV project and represented the BBC on EBU and Eureka committees as a color scientist. From this HDTV work in the 1980s and 90s he developed the “film-look” favored by drama and wildlife programmakers, devising ways to use the new technology to lower production costs without compromising quality. — Now retired, he continues as a consultant on color science and HDTV matters, advising manufacturers and programmakers on HDTV developments.
