Abstract
Procédé et montage de sélection de piste, notamment pour magnétoscopes. On positionne transversalement la tête transductrice pour lui faire suivre avec précision une piste et, à la fin de cette piste, lui faire reproduire la piste immédiatement adjacente, ou une seconde fois la même piste, ou encore une autre piste, pour assurer un effet de mouvement spécial. Dans l'accélération de la bande jusqu'à vitesse normale, le dérouleur est initialement commandé à partir d'une piste de commande enregistrée pour positionner la tête par rapport aux pistes enregistrées, et transformer le signal vidéo reproduit en images couleurs par comparaison avec une référence de studio. Applicable notamment aux appareils à balayage hélicoïdal.
