Abstract

L'invention concerne des systèmes et des procédés pour simuler une expérience télévisuelle classique avec transmission en continu d'un contenu à la demande. Un contenu diffusé en continu peut être mis en tampon afin de permettre à un utilisateur de prévisualiser un contenu même lorsque le contenu n'est pas organisé sous un format de canal numéroté classique. Un utilisateur peut progresser à travers une série d'éléments de contenu (par exemple canal simulé vers le haut/vers le bas) afin de prévisualiser le contenu à la demande sans avoir à trop attendre que chaque élément de contenu se charge et/ou se mette en tampon.
