Abstract

L'invention permet d'incorporer dans un module de télévision une radio satellitaire. Elle a la possibilité de faire une commutation (MARCHE/ARRET) entre le module vidéo, le tube cathodique et le module radio satellitaire. Le module radio satellitaire comprend un syntoniseur de fréquence, la commande du volume, et autre commande pouvant être visualisées soit sur a) l'écran de télévision, soit sur b) l'écran d'affichage à cristaux liquides. L'invention porte également sur un accessoire pour le port numérique adapté au récepteur de télévision qui permet la connexion de services multimédia, et notamment les images à défilement lent, le courrier électronique, mais aussi la connexion d'ordinateurs de bureau et d'ordinateurs portables, etc. Le dispositif de commutation (MARCHE/ARRET) permet notamment de se servir du module vidéo en mode audio. L'amplificateur audio et le haut-parleur du module de télévision sont communs à la radio satellitaire et aux circuits l'audio du module de télévision.
