Abstract

L'invention concerne l'enregistrement et la reproduction magnétiques de signaux vidéo. Dans le dispositif d'enregistrement de l'invention, la composante de chrominance des signaux vidéo est appliquée à un changeur de fréquence 28 avant d'être combinée à la composante de luminance en modulation d'angle, pour donner le signal composite qui est enregistré par les têtes magnétiques 11a et 11b. La phase du signal de décalage de fréquence qui est appliqué au changeur de fréquence 28 est modifiée d'un intervalle de ligne au suivant, pour permettre de supprimer la diaphonie entre pistes adjacentes, au cours de la reproduction. Application aux magnétoscopes pour la télévision en couleur.
