Abstract

Cette invention se rapporte à un système de commande vidéo peu coûteux, qui est de conception simple et qui se prête à un usage domestique. Une partie des signaux vidéo contenant plusieurs blocs d'informations d'images sont convertis aux moments demandés en données de commande correspondant aux instructions de fonctionnement et enregistrés dans un magnétoscope vidéo (VTR) (22). Les signaux vidéo enregistrés sont reproduits au moyen d'un dispositif de reproduction et les données de commande contenues dans les signaux vidéo sont détectées par un circuit de commande (33). Ce circuit (33) fournit les données de commande à un système commandé (50), lequel fonctionne en harmonie avec les images ou la musique reproduites. Ce système commandé (50) peut être constitué par n'importe quelle installation, pourvu qu'elle fonctionne en accord avec les données de commande, par exemple une installation d'éclairage ou un affichage mobile pour une exposition.
