Abstract

Système de télécommande d'un appareil de reproduction d'informations de type audio-visuel. La bande comporte une piste d'adresses portant des mots codés partageant la bande en éléments de longueur consécutifs associes chacun à une adresse particulière. Le système comporte des premiers moyens de repérage susceptibles de fournir une information dite d'adresse réelle relative au tronçon de bande passant devant la tête de lecture 12, par lecture des mots codés de la piste d'adresses et une unité de recherche 21 connectée aux premiers moyens de repérage et aux moyens de commande d'entraînement 15 à 18 pour commander le positionnement de la bande afin d'amener devant la tête de lecture un élément de longueur de la bande d'adresse prédéterminée. Des seconds moyens de repérage 20 fournissent une information approchée de la position de la bande à un instant donné pour declencher une première phase de positionnement approximatif de la bande à vitesse rapide. Ce système convient notamment au positionnement d'une bande de magnétophone ou magnétoscope au début d'une séquence
