Abstract

L'invention concerne un système de diffusion en continu à demande de blocage produisant une diffusion en continu à latence faible d'une présentation multimédia. Une pluralité de segments multimédia est générée selon un protocole de codage. Chaque segment multimédia comprend un point d'accès aléatoire. Une pluralité de fragments multimédia est codée selon le même protocole. Les segments multimédia sont agrégés à partir d'une pluralité de fragments multimédia.
