  • the multiple connectors include five connectors for connecting to the RG 200: three video connectors 850, such as coaxial connectors; a connector 852 for the channel select command, such as an audio pendant; and a connector 864 for connecting the telecommunications network to the RG 200, such as a RJ-45 pendant.
  • the multiple connectors also include two connectors for connecting to other devices: a connector 860, such as coaxial connector, for the local TV 199; and a connector 862, such as a coaxial connector, for the remote devices.
  • Fig. 16 illustrates one embodiment of the housing of the MID 800. As illustrated the MID 800 includes three video connectors 850 which would be adequately spaced so that the MID 800 could be directly attached to the connectors on the RG 200.
  • the MID 800 also includes the two connectors 860, 862 for the local TV 199 and the remotely located devices, as well as a pendant 864 for connecting the MID 800 to the network input of the RG 200 and a pendant 852 for connecting to the channel select command port, audio port, of the RG 200.
  • the MID 800 may have a die cast housing, and is preferably die cast from tin plated zinc. The MID 800 should be produced so as to shield the various modules within the MID 800 from each other and external radiation. All of the coaxial connectors should be built into the housing.

Abstract

L'invention concerne une passerelle résidentielle (200) permettant de distribuer des services vidéo, des services d'accès aux données et des services téléphoniques à plusieurs dispositifs d'une résidence. La passerelle (200) reçoit les signaux transmis par un réseau de télécommunication, converti ces signaux dans des formats compatibles avec les divers dispositifs, puis elle transmet les signaux appropriés aux dispositifs appropriés. Des dispositifs de commande à distance sans fil, associés aux télévisions placées à distance (199), transmettent à la passerelle résidentielle (200) des commandes de sélection de canal sous la forme de signaux sans fil. Les signaux sans fil sont reçus par un ensemble d'antennes à distance (900) qui transmet par câble le signal sans fil. Un module d'antennes à distance (920) reçoit le signal sans fil et extrait la commande de sélection de canal.
