Abstract

L'invention concerne un système et un procédé de lecture de vidéo. Le système de lecture de vidéo comprend : un premier terminal, un second terminal et un serveur en nuage. Le serveur en nuage est utilisé pour fournir un contenu de lecture, le contenu de lecture comportant des informations d'index, les informations d'index étant associées au contenu de lecture. Le premier terminal est utilisé pour acquérir le contenu de lecture à partir du serveur en nuage et afficher le contenu de lecture, et envoyer les informations d'index au second terminal. Le second terminal est utilisé pour acquérir un contenu d'extension correspondant aux informations d'index, et afficher de manière synchrone le contenu d'extension durant la lecture du contenu de lecture. Le système de lecture de vidéo de la présente invention permet à un spectateur de trouver de manière plus commode des informations associées, tout en n'affectant pas la visualisation normale d'une vidéo de réseau par le spectateur, permettant ainsi d'étendre de manière significative le contenu de la vidéo de réseau, et de fournir à l'utilisateur une meilleure expérience de visualisation.
