Abstract

Un procédé de traitement d’un flux vidéo comprenant une séquence d’images est proposé, qui comprend, à une unité de gestion de flux vidéo : démultiplexer le flux vidéo pour générer un flux vidéo élémentaire et des métadonnées relatives au flux vidéo ; générer des données de sous-titrage d’une image du flux vidéo élémentaire sur la base des métadonnées ; insérer des données d’horodatage de l’image dans les données de sous-titrage ; et multiplexer le flux vidéo élémentaire et les données de sous-titrage pour générer un flux vidéo enrichi. Figure de l’abrégé : Figure 2A method of processing a video stream comprising a sequence of images is proposed, which comprises, at a video stream management unit: demultiplexing the video stream to generate an elementary video stream and metadata relating to the video stream; generating caption data of a frame of the elementary video stream based on the metadata; insert image timestamp data into caption data; and multiplexing the basic video stream and the subtitle data to generate an enriched video stream.
