Abstract

La présente invention concerne un procédé et un appareil pour une projection sur écran d'une vidéo. Le procédé consiste : lors de la lecture d'une vidéo sur un premier dispositif, à projeter, selon une instruction de projection sur écran d'un utilisateur, une image d'une vidéo affichée sur le premier dispositif sur un second dispositif destiné à un affichage ; et à afficher, sur le premier dispositif, une interface de commentaire par rapport à la vidéo, l'interface de commentaire étant mise en œuvre afin de recevoir une entrée de commentaire par l'utilisateur et afin d'afficher cette dernière. Lors de la réception de l'instruction de projection sur écran, le premier dispositif affiche simplement l'interface de commentaire ayant une fenêtre d'entrée et une fenêtre d'affichage, et n'affiche pas l'image de la vidéo, ainsi, l'utilisateur peut entrer et regarder, sur le premier dispositif, un commentaire à l'aide de l'interface de commentaire, et regarder, sur un écran du second dispositif, la vidéo, de telle sorte que l'interface de commentaire ne recouvre pas l'image de la vidéo, et il est garanti que l'entrée d'un commentaire et la visualisation d'un commentaire n'interfèrent pas avec la visualisation de la vidéo pour l'utilisateur. Par conséquent, la solution proposée dans la présente invention peut améliorer l'expérience de visualisation de film d'un utilisateur.
