Abstract: The crux of the move to ultrahigh-definition television is to simply deliver a wider field of view, which only requires an increase in pixel count to 3840 × 2160 or 7680 × 4320 pixels, which are well accepted standards. However, this overlooks important factors such as color/tone rendition and motion portrayal, which could be crucial to delivering an enhanced visual experience with next-generation television (next-gen TV) systems. To this end, system parameters are proposed including colorimetry and frame frequency for next-gen TV. The proposed colorimetry system is based on the real RGB color system and has a color gamut covering 99.9% of real surface colors while using physically realizable RGB primaries. Further, a frame frequency of 120 Hz is proposed on the basis of subjective assessments of motion picture quality.
