Abstract

Des services réseau encodent un contenu multimédia, vidéo par ex., dans une pluralité de flux de débit adaptatif de vidéo encodée et un flux trick play séparé de vidéo encodée pour prendre en charge des fonctions trick play. Le flux trick play est encodé à un débit d'encodage et un débit de trames inférieurs à ceux de chacun des flux de débit adaptatif. Les flux de débit adaptatif et les flux trick play sont stockés dans des services réseau. Lors d'une diffusion en continu normale de contenu et la lecture, un dispositif client télécharge un des flux de débit adaptatif sélectionné, du réseau desservi pour la lecture, au dispositif client. Pour implémenter une fonction trick play, le dispositif client télécharge le flux trick play, des services réseau, pour la lecture trick play.
