Abstract

L'invention concerne un système de communication et plus particulièrement, mais non pas exclusivement, un système de communication visuelle et audio. Ce système est constitué d'une caméra vidéo qui est connectée à un émetteur récepteur portable sans fil. Une image en provenance de la caméra vidéo est transmise de l'émetteur récepteur sans fil vers un répétiteur de signal à partir duquel le signal vidéo est transmis via un système de communication téléphonique vers un second émetteur récepteur. Ce dernier est disposé de manière à afficher le signal vidéo sur un afficheur. Un premier contrôleur est relié au second émetteur récepteur pour transmettre un signal de commande via le système de communication téléphonique vers le répétiteur de signal et de ce dernier vers l'émetteur récepteur portable sans fil et au second contrôleur connecté à l'émetteur récepteur portable pour le contrôle de la caméra vidéo ou d'un utilisateur de la caméra vidéo. La classification est H04N, H04M, H04L.
