Abstract

Une pluralité de signaux d'entrée simultanés sont envoyés successivement à un système de décodage d'informations supplémentaire par commutation, à un moment prédéfini, d'un système de commutation, puis des informations supplémentaires contenues dans chaque signal d'entrée sont détectées et décodées. Une pluralité d'images correspondant aux informations supplémentaires sont ainsi générées à partir des signaux d'entrée et affichées sur le même écran.
