Abstract

La présente invention porte sur un procédé et un appareil de traitement de service vidéo, et sur un dispositif de réseau. Le procédé consiste : à identifier un paquet de données du même service vidéo par le même utilisateur de requête ; à associer un paquet de données de requête vidéo, un paquet de données de réponse vidéo et un paquet de données de contenu vidéo dans un clip vidéo ; et à déterminer un KQI du service vidéo en fonction du clip vidéo. Grâce à l'association de paquets de données du même service vidéo destinée à obtenir un clip vidéo, il est possible d'obtenir un flux vidéo précis et complet. Il est avantageux d'appliquer le flux vidéo précis et complet pour effectuer une analyse de qualité vidéo afin de refléter parfaitement l'expérience utilisateur et de finalement atteindre l'objectif de promotion du KQI de service vidéo.
