Abstract

L'invention concerne un système et un procédé de connexion d'une pluralité de dispositifs par un support sans fil par l'intermédiaire d'une interface. Le système comprend un sous-système d'appariement de dispositifs configuré pour permettre l'appariement entre une pluralité de dispositifs d'entrée et une pluralité correspondante de dispositifs de sortie par l'intermédiaire d'au moins un support de communication sans fil, un sous-système d'identification de dispositifs (5) configuré pour identifier un ou plusieurs paramètres d'entrée et un ou plusieurs paramètres de sortie, un sous-système de configuration configuré pour transmettre un signal d'initialisation, pour recevoir un signal de fonctionnement et pour calculer un retard temporel, un sous-système de synchronisation de dispositifs configuré pour synchroniser la pluralité de dispositifs d'entrée avec la pluralité correspondante de dispositifs de sortie, un sous-système de transmission de données (10) configuré pour permettre la transmission de données. Le système permet à l'utilisateur de transmettre des données depuis un dispositif d'entrée à de multiples dispositifs de sortie, avec des versions variables et une fréquence de fonctionnement variable correspondante, rendant ainsi le système réalisable et efficace en termes de temps.
