Title
(EN) A METHOD AND APPARATUS FOR LOOP-PLAYING VIDEO CONTENT
(FR) PROCÉDÉ ET APPAREIL DE LECTURE EN BOUCLE DE CONTENU VIDÉO
Abstract
(EN)
Methods and devices are provided to play back a video content item comprising loop sequences. The player manages two or three playing modes and switch between first-in first-out video buffer and circular video buffer with a size adapted to the loop sequences for which the player is in loop mode. A start point and an end point are obtained for each loop sequence of the video. In an embodiment, a code is associated with frames of the video to indicate to which loop(s) a frame belongs to.
(FR)
L'invention concerne des procédés et des dispositifs de lecture d'un élément de contenu vidéo comprenant des séquences de boucle. Le lecteur gère deux ou trois modes de lecture et commute entre un tampon vidéo premier entré premier sorti et un tampon vidéo circulaire ayant une taille adaptée aux séquences de boucle pour lesquelles le lecteur est en mode de boucle. Un point de départ et un point final sont obtenus pour chaque séquence de boucle de la vidéo. Selon un mode de réalisation, un code est associé à des trames de la vidéo pour indiquer à quelle ou auxquelles boucles appartient une trame.
