Abstract
(EN)
Systems, methods, and devices are disclosed enabling smart search functionalities utilizing key scene changes appearing in video content. In various embodiments, the method includes the step or process of, while engaged in playback of the video content, receiving a user command at a playback device to shift a current playback position of the video content to a default search playback position (PPDS). In response to receipt of the user command, the playback device searches a time window encompassing the default search playback position (PPDS) for a key scene change in the video content. If locating a key scene change within the time window, the playback device shifts playback of the video content to a playback position corresponding to the key scene change (PPST). Otherwise, the playback device shifts playback of the video content to the default search playback position (PPDS).

L'invention concerne des systèmes, des procédés et des dispositifs activant des fonctionnalités de recherche intelligente utilisant des changements de scène clés apparaissant dans un contenu vidéo. Dans divers modes de réalisation, le procédé comprend l'étape ou le processus consistant, pendant que la lecture du contenu vidéo est engagée, à recevoir une commande d'utilisateur au niveau d'un dispositif de lecture pour déplacer une position de lecture actuelle du contenu vidéo jusqu'à une position de lecture de recherche par défaut (PPDS). En réponse à la réception de la commande d'utilisateur, le dispositif de lecture recherche une fenêtre temporelle englobant la position de lecture de recherche par défaut (PPDS) pour un changement de scène clé dans le contenu vidéo. Si un changement de scène clé est localisé dans la fenêtre temporelle, le dispositif de lecture déplace la lecture du contenu vidéo vers une position de lecture correspondant au changement de scène clé (PPST). Sinon, le dispositif de lecture déplace la lecture du contenu vidéo vers une position de lecture de recherche par défaut (PPDS).
