Abstract

La présente invention concerne un système permettant d'enregistrer virtuellement un contenu vidéo qui est, par l'intermédiaire d'un réseau distribué, relié à un système de télévision multicanaux, qui transmet différents programmes sur des canaux différents. Le système comprend un moyen de stockage relié au réseau distribué, qui enregistre et stocke en continu chaque programme, seulement une fois, avec une identification unique. Le système comprend également un moyen de commande relié au réseau distribué et un dispositif utilisateur relié au réseau distribué, ainsi qu'un moyen d'interface. Un utilisateur sélectionne différents programmes à l'aide du moyen d'interface. Le dispositif utilisateur conserve le moyen d'identification unique pour les programmes sélectionnés. Le moyen d'interface présente les programmes sélectionnés par l'utilisateur. Lorsque l'utilisateur veut voir un programme mémorisé spécifique faisant partie des programmes sélectionnés présentés et qu'il sélectionne le programme spécifique, l'utilisateur envoie une demande au moyen de commande qui détermine si la demande peut être accordée. Si la demande est accordée, le dispositif utilisateur se connecte au moyen de stockage et envoie à ce dernier le moyen d'identification unique pour le programme spécifique, puis le dispositif utilisateur lit le programme spécifique.
