Abstract

La présente invention, selon un mode de réalisation, concerne un système de communication comprenant : un appareil d'émission et un appareil relais connecté entre l'appareil d'émission et chacun de plusieurs appareils de réception. L'appareil relais comprend une première unité de réception, une unité de gestion de liste de dispositifs et une première unité d'émission. La première unité de réception reçoit, des plusieurs appareils de réception, leurs éléments d'informations respectifs de modèle. L'unité de gestion de liste de dispositifs génère, pour chacun de plusieurs éléments d'informations d'identification de port permettant d'identifier les ports respectifs auxquels sont connectés les appareils respectifs parmi les plusieurs appareils de réception, un élément d'information respectif de liste de dispositifs obtenu par association d'un élément d'information respectif d'identification de dispositif permettant d'identifier l'appareil respectif parmi les appareils de réception avec un élément d'information de position associé à la position de l'appareil relais. La première unité d'émission transmet les éléments d'informations de liste de dispositifs à l'appareil d'émission. L'appareil d'émission transmet, à l'appareil relais, une instruction qui désigne l'élément d'information d'identification de port correspondant, parmi les éléments d'informations de liste de dispositifs, à l'élément d'information d'identification de dispositif de l'appareil, parmi les appareils de réception, qui doit faire l'objet d'un accès et qui désigne également l'élément d'information de position de l'appareil relais.
