Abstract

L'invention concerne une architecture de système permettant une distribution commandée de signaux vidéo, et/ou audio, et/ou de données (v/a/d) dans d'une maison ou une entreprise, laquelle architecture comprend une unique "mini tête de réseau" (302) permettant de recevoir des signaux vidéo/audio/de données (308) et de distribuer ces signaux v/a/d (308) aux unités de présentation (304) dans la maison ou l'entreprise. Cette mini tête de réseau (302) peut recevoir des signaux v/a/d (308) de différentes sources. Sur la base de signaux de commande reçus d'une ou plusieurs unités de commande (306), ladite mini tête de réseau (302) choisit des signaux v/a/d (308) pour une modulation en une pluralité de signaux porteurs ou de voies de communication. Les signaux porteurs sont multiplexés en un signal de distribution transmis aux unité de présentation (304).
