Abstract

a. Procédé servant à mémoriser un signal de télévision couleur. b. Ce procédé se caractérise essentiellement en ce que les composantes de luminance et de chrominance du signal de télévision couleur sont mémorisées séparément. On enregistre dans une mémoire, à titre de composante de chrominance, à la séquence de ligne, un signal de sommation et un signal de différence de signaux de différence de couleur à fréquence vidéo. Les signaux de sommation et de différence lus en mémoire sont convertis pour un recodage ultérieur en signaux de différence de couleur. c. L'invention s'applique principalement à la télévision couleur.
