Abstract

L'invention concerne un système et un procédé pour commander à distance des dispositifs domotiques depuis l'extérieur d'une habitation. Selon l'invention, un dispositif de passerelle indépendant, comprenant un serveur multimédia numérique virtuel (VDMS), un dispositif de passerelle Internet (IGD) UPnP et une unité de sécurité du dispositif, peut être ajouté à un réseau domestique. Dans une variante, un serveur VDMS et une unité de sécurité du dispositif peuvent être installés dans un dispositif conforme à l'alliance DLNA (Digital Living Network Alliance), tel qu'un serveur numérique, et uniquement un dispositif IGD UPnP peut être installé au moyen d'un dispositif de passerelle. Ainsi, un utilisateur situé à l'extérieur d'une habitation peut accéder à distance à des appareils électroménagers, installés dans l'habitation, par l'intermédiaire d'un dispositif mobile et peut transmettre en continu des données. En conséquence, un service de transmission multimédia limité à l'intérieur d'une habitation, ce qui correspond à la limitation des dispositifs UPnP et DLNA existants, peut être étendu et utilisé par l'intermédiaire d'un réseau extérieur. En outre, un interfonctionnement entre un dispositif mobile et un réseau domestique, couramment utilisé aujourd'hui, peut être mis en oeuvre de manière plus pratique grâce à cette extension, ce qui permet de fournir des services reposant sur un interfonctionnement entre un réseau domestique et un réseau à large bande.
