13-1 色度伝送による画質改善の検討  [in Japanese] Consideration on Picture Quality Improvement by Chromaticity Signals Transmissiion  [in Japanese]

Possibility of picture quality improvement by transmission of chromaticity signals when chromatic signals are band-limited in narrow range on transmission routes, is studied. A chromaticity transmission system is proposed and examined. In a saturated color picture, picture quality was improved by the system as compared with a constant luminance system.
