Abstract

L'invention concerne un procédé de commande entre des dispositifs interactifs à écrans multiples. Un dispositif maître et un dispositif esclave sont des dispositifs interactifs à écrans multiples prenant en charge différents types de protocoles interactifs à écrans multiples. Le procédé comprend les étapes suivantes : un dispositif maître envoie des informations d'identification à un dispositif esclave, les informations d'identification comprenant des informations de description de protocoles interactifs à écrans multiples prédéfinis ; reçoit des informations de réponse retournées par le dispositif esclave en fonction des informations d'identification, les informations de réponse étant produites par le dispositif esclave en fonction des informations de description, d'un protocole interactif à écrans multiples dont le type est le même qu'un type pris en charge par le dispositif esclave, dans les informations d'identification ; et obtient un type de protocole interactif à écrans multiples pris en charge par le dispositif esclave en fonction des informations de réponse, puis envoie une instruction de commande correspondante au dispositif esclave en fonction du type de protocole interactif à écrans multiples pris en charge par le dispositif esclave. L'invention concerne également un dispositif interactif à écrans multiples et un système de commande entre des dispositifs interactifs à écrans multiples. La présente invention met en place une commande mutuelle entre des dispositifs interactifs à écrans multiples prenant en charge différents types de protocole interactif à écrans multiples et rend l'utilisation de dispositifs interactifs à écrans multiples prenant en charge différents protocoles interactifs à écrans multiples pratique pour les utilisateurs.
