Abstract

L'invention concerne un procédé et un dispositif de traitement vidéo, ledit procédé consistant à : recevoir un premier contenu vidéo d'un réseau de distribution de contenu (CDN), le débit binaire du premier contenu vidéo étant supérieur à une valeur de seuil prédéfinie; exécuter un processus de transcodage sur le premier contenu vidéo pour obtenir un second contenu vidéo présentant un débit binaire inférieur à la valeur de seuil prédéfinie; et envoyer le second contenu vidéo au CDN. L'invention résout le problème lié, dans l'état de la technique, au fait qu'il est impossible de fournir un service de lecture vidéo haute définition pour un utilisateur à faible bande passante, ce qui permet de fournir un service de lecture vidéo haute définition pour un utilisateur à faible bande passante, et d'améliorer ainsi l'expérience de l'utilisateur.
