Abstract

Reproduction de signaux vidéo. On prévoit des moyens de commande et de contrôle 26, 28-42 pour reproduire un signal de commande formé à partir d'une bande magnétique et ainsi effectuer une commande. de telle manière que la première tête tournante démarre son exploration à partir de l'extrémité de départ de la piste enregistrée et formée par la tête tournante de même angle d'azimut que la première tête tournante, au moins une seconde tête 13b présentant une largeur W2 supérieure à la largeur de la piste T etant dilatée depuis le'bord de la piste avec lequel doit commencer l'exploration jusqu'à un côté d'avance de phase par rapport à la direction de déplacement de la bande. Reproduction de signaux vidéo à des vitesses différentes.
