Abstract: As technology improvements have been steadily implemented in both the Television and Cinema industries, one of the most neglected topics has been color. Still hampered by CRT-era color specifications and relatively simplistic color mapping methods, these industries are overdue for a change. Change is coming, in the form of new color spaces like ultra-high definition television (UHDTV) and Academy Color Encoding System (ACES). These new systems bring greater capabilities than the current spaces of Rec.709 and P3, but they also bring new challenges. Larger color spaces create trade-offs in precision and efficiency, and they bring added complexity as color encoding spaces are no longer rigidly tied to display color gamuts. Techniques for gamut mapping from one space to another become critical to the success of these new formats, and a greater understanding of human color perception is required to maximize the potential of these exciting new developments. This article will review the history and current status of color system developments.

bio
Scott Miller is a senior member of the technical staff at Dolby Laboratories where he serves in the Image Technology Research group. He specializes in image display technology and video signal processing, most recently working on Dolby's Professional Reference Monitor. Miller received a B.S. in electrical engineering from Cornell University and has spent nearly 30 years working in the video industry, including several years with Panasonic Research where he helped develop the Emmyaward winning Universal Video Format Converter.
Scott Daly
bio
Scott Daly received a B.S. EE degree in 1980 from North Carolina State University, and then worked with early high-resolution laser scanning systems at Photo Electronics Corp. in West Palm Beach, FL. Shifting from hardware to wetware, he obtained an M.S. in bioengineering from the University of Utah in 1984, completing a neurophysiology thesis on the temporal processing of cone photoreceptors. He then worked in the Imaging Science Division at Eastman Kodak in the fields of image compression, image fidelity models, and image watermarking. — Daly then worked at Sharp Laboratories of America in Washington state, where he led a group on display algorithms. Becoming a research fellow, he applied visual models towards digital video and displays, with publications on spatiotemporal and motion imagery, human interaction with wall-sized displays, and stereoscopic displays. These topics led him to join Dolby Laboratories in 2010 to focus on overall fundamental perceptual issues, and efforts to preserve artistic intent throughout the entire video path to reach the viewer. He is currently a member of Institute of Electrical and Electronics Engineers (IEEE), Society of Photo-Optical Instrumentation Engineers (SPIE), and Society for Information Display (SID).
Craig Todd
bio
Craig Todd is Sr. vice president and chief technical officer at Dolby Laboratories. He has a Bachelors degree in physics from the California Institute of Technology, and has been with Dolby since 1977. Todd is one of the primary designers of Dolby Digital and Dolby E coding technologies, and he was heavily involved in the ACATS/ATSC effort to set the DTV standard for the U.S. Current interests include bringing 3D, wide color gamut, and high dynamic range imagery into the home via both legacy, and new electronic media, formats. — Todd has participated in a variety of standards-setting activities in the International Telecommunications Union-Radiocommunication Sector (ITU-R), Digital Video Broadcasting (DVB), Audio Engineering Society (AES), International Electrotechnical Commission (IEC), Consumer Electronics Association (CEA), Advanced Television Systems Committee (ATSC) and SMPTE. He currently serves on the Board of ATSC and is a vice-chair of ITU-R Working Party 6C. He is a recipient of the SMPTE Samuel L. Warner Medal for achievement in motion picture sound, and of an Emmy for loudness metering, and holds more than 20 patents.
