Abstract

L'invention porte sur un procédé de mise en mémoire cache qui permet de relire une diffusion en direct, ainsi que sur un procédé de lecture et sur un système de lecture. Le procédé de mise en cache qui permet de relire une diffusion en direct consiste : à télécharger un fichier de fragment multimédia TS par le biais d'une station source de canal; à stocker le fichier de fragment multimédia TS dans une mémoire; selon un laps de temps préétabli, à stocker régulièrement, dans un DFS, le fichier de fragment multimédia TS stocké dans la mémoire et à supprimer le fichier de fragment multimédia TS correspondant dans la mémoire. L'invention concerne en outre un système de mise en cache qui permet de relire une diffusion en direct et qui comprend : une unité de téléchargement configurée de sorte à télécharger un fichier de fragment multimédia TS par le biais d'une station source de canal; une première unité de stockage configurée de sorte à stocker le fichier de fragment multimédia TS dans une mémoire; une seconde unité de stockage configurée de sorte à stocker régulièrement, dans un DFS et selon un laps de temps préétabli, le fichier de fragment multimédia TS stocké dans la mémoire et à supprimer le fichier de fragment multimédia TS correspondant dans la mémoire.
