Abstract

La présente invention concerne un procédé et un appareil de lecture vidéo. Le procédé consiste à : détecter des informations-clé associées à une vidéo lors d'une lecture de la vidéo ; et mettre en évidence les informations-clé dans l'image vidéo lors de la détection des informations-clé. Dans la présente invention, les informations-clé détectées, relatives à la vidéo, sont mises en évidence dans l'image vidéo pendant la lecture de la vidéo. Cela permet à un utilisateur de déterminer un contenu lu dans l'image vidéo au moyen des informations-clé mises en évidence pendant la lecture de la vidéo, de ne pas manquer un contenu d'intérêt et d'économiser du temps de visualisation.
