Abstract

Selon un mode de réalisation, la présente invention concerne un équipement de commutation automatique de source de signaux de télévision, qui comprend une unité d'interface et une première unité de commande de commutateur qui sont connectées l'une après l'autre. La première unité de commande de commutateur est connectée à une interface d'entrée de signaux d'une télévision. Les unités d'interface comprennent une pluralité d'interfaces, chaque interface pouvant être connectée extérieurement à une source de signaux de télévision. La première unité de commande de commutateur comprend une pluralité de premiers commutateurs de commande, chacun des premiers commutateurs de commande correspondant à une interface dans l'unité d'interface, une extrémité de chacun des premiers commutateurs de commande étant connectée à une interface dans l'unité d'interface et l'autre extrémité étant connectée à l'interface d'entrée de signaux de la télévision. Lorsqu'une interface dans l'unité d'interface est connectée extérieurement à une source de signaux de télévision, les premiers commutateurs de commande connectés à l'interface sont activés de manière que l'interface soit connectée à l'interface d'entrée de signaux de la télévision. La présente invention peut résoudre le problème en l'état de la technique selon lequel, lorsque l'utilisateur insère à nouveau une source de signaux, la télévision ne peut pas lire automatiquement le contenu correspondant fourni par la source de signaux.
