Abstract

Procédé de commande de l'inversion du sens de transport de la bande dans un système d'enregistrement et de reproduction vidéo couleur à bande. On enregistre, pendant une partie au moins de chaque intervalle de suppression de ligne, des impulsions de couleur ayant une fréquence qui est seulement une fraction de la fréquence du blanc du signal vidéo modulé et on enregistre ladite impulsion pendant au moins un intervalle prédéterminé de suppression d'image à l'instant de l'inversion pour produire un signal de commande de l'inversion; on capte ledit signal de commande enregistré et on déclenche une opération d'inversion de la bande qui est contrôlée au moins en partie par la détection dudit signal.
