Abstract
Color television systems have always assumed a specific display with the color coding in the camera and transmission system derived from this display using the CIE system of colorimetric specification. However, display phosphors have changed since the beginnings of color television resulting in increased display luminance but at the expense of significantly reduced color gamut that can be displayed. Since camera characteristics have changed to be compatible with current CRT displays, the color gamut that is captured and transmitted is limited to that of current CRT displays. We will likely see new display technologies in the future and these displays may well be capable of displaying a larger color gamut than current CRT's. Also other imaging systems, such as film, have color gamuts larger than current CRT's, so interoperability with other imaging systems demands a larger color gamut. For future television we need to define a source coding colorimetry that satisfies our long term need for a larger color gamut. We than perform color transformations at system interfaces and in some displays to derive the signals appropriate for that specific system or display. Two approaches for capturing a larger color gamut are considered. The second approach, allowing negative and above white RGB signals, seems to be the most readily implemented with current technology and is being evaluated for inclusion into the production standards for future television systems.
