Abstract

Procédé de fabrication d'une note vidéo. Le procédé comprend : lorsqu'un utilisateur enregistre une vidéo ou regarde une vidéo, la définition d'une pluralité de mots-clés à l'avance, l'identification des mots-clés par la voix pendant le processus d'enregistrement, et l'enregistrement du moment où les mots-clés sont identifiés, pour former des étiquettes de vidéo de « mot-clé » + « moment » ; et l'enregistrement d'un mot-clé, d'un numéro de page, du moment de début et du moment de fin d'une note saisie par l'utilisateur, pour former une étiquette de note de « numéro de page » + « mot-clé » + « moment de début » + « moment de fin ». Selon l'association entre l'étiquette de note et les étiquettes de vidéo, une association entre la vidéo et la note est formée. L'utilisateur n'a pas besoin d'effectuer une édition secondaire sur la vidéo et peut procéder à la mise en correspondance de la vidéo et d'une note une fois l'enregistrement terminé, ce qui améliore la flexibilité et la commodité d'une note vidéo électronique.
