Abstract

La présente invention concerne un système vidéo à la demande de fourniture de contenus multimédia, qui active des contenus publicitaires par la détection d'un pointeur de coupure. Ledit système est caractérisé en ce que ledit pointeur de coupure est inclus dans le contenu multimédia principal. Selon la présente invention, il est facile de procéder à l'insertion de divers types de messages publicitaires pendant l'affichage du contenu principal, de manière que les messages publicitaires insérés sont sélectionnés en fonction de l'heure de diffusion du contenu principal et en fonction d'informations relatives au spectateur, notamment son âge, sa profession, son adresse privée, etc.
