Abstract

La présente invention concerne le domaine des ordinateurs. Selon des modes de réalisation, l'invention concerne un procédé, une plateforme et un système destinés à bâtir une bibliothèque d'informations associées d'une vidéo et à lire la vidéo. Le procédé comprend les étapes suivantes : obtenir, à partir d'une vidéo originale, une ou plusieurs trames vidéo continues, en fonction des cycles de vie de différentes cibles à définir; déterminer, dans une ou plusieurs trames vidéo continues correspondant à une cible, des informations de profil et une priorité d'affichage de la cible prédéfinie dans chaque trame vidéo; puis créer une bibliothèque d'informations associées relative à la vidéo d'origine selon les informations de profil et la priorité d'affichage de la cible dans chaque trame vidéo. Dans la présente invention, une ou plusieurs trames vidéo continues sont obtenues à partir d'une vidéo d'origine, en fonction des cycles de vie correspondant aux cibles, puis des informations de profil et une priorité d'affichage d'une cible prédéfinie par un utilisateur de la production vidéo sont déterminées dans la ou les trames vidéo continues, ce qui résout l'inconvénient de l'état de la technique, selon lequel les informations associées sont vides lorsque la cible est recouverte par l'arrière-plan ou d'autres cibles dans la bibliothèque d'informations associées.
