Abstract

L'invention porte sur un système destiné à vendre de la musique/vidéo diffusée comme un programme. Ce système comprend un appareil (100) de diffusion et une pluralité d'unités (400) d'écoute/visualisation. L'appareil (100) de diffusion enregistre la musique/vidéo et la diffuse comme un programme dans un réseau (200) de diffusion. Lorsque l'appareil (100) de diffusion diffuse la musique/vidéo comme un programme, le bruit codé est mélangé de façon à protéger le droit d'auteur de la musique/vidéo diffusée. Lorsqu'un utilisateur veut visualiser la musique/vidéo et l'acheter, l'unité (400) d'écoute/visualisation transmet les données de demande d'achat à l'appareil (100) de diffusion par un réseau (300) de communication. L'appareil (100) de diffusion envoie la musique/vidéo demandée à l'unité (400) d'écoute/visualisation par le réseau (300) de communication ou le réseau (200) de diffusion.
