HDTV Production Colorimetry

L. E. DeMarsh

This article is a summary of the activities of the SMPTE Ad Hoc Group on HDTV Production Colorimetry, which the author has been chairman of since its formation in 1985. The colorimetry of an HDTV production system presents different problems than do current TV systems. HDTV must be planned to accommodate a wide range of displays, some not yet invented. It must also serve as a source signal for motion-picture film and be transformable to other television systems. The key concerns are to define the source HDTV signal completely, independent from a specific display and with a color gamut large enough to accommodate future display technologies. The signal processing also should be designed to preserve the maximum amount of information for post-production signal processing. The committee's approach to addressing these requirements is described.
