Abstract

L'invention concerne l'enregistrement et la reproduction de signaux vidéo. La partie reproductrice d'un magnétoscope comporte un circuit de commande automatique de phase CAP et un circuit de commande automatique de fréquence CAF. Grâce à un amplificateur à seuil 25, le signal de sortie du circuit de commande automatique de fréquence n'agit que lorsque l'erreur de base de temps dépasse la plage de verrouillage du circuit de commande automatique de phase. Application aux magnétoscopes pour la télévision en couleur.
