Title
(EN) METHOD FOR SYNCHRONIZING THE PLAYBACK OF AN AUDIO FILE WITH AN ASSOCIATED VIDEO FILE
(FR) PROCÉDÉ DE SYNCHRONISATION DE LA LECTURE D'UN FICHIER AUDIO AVEC UN FICHIER VIDÉO ASSOCIÉ
Abstract
(EN) The present invention relates to a method for the synchronization of the playback of an audio file with the playback of a related video file, and particularly to the method for synchronizing a video and an audio file being simultaneously reproduced by a video client player and an audio client player, respectively, by means of computing an audio playback position with video playback position signals and timestamp signals received from the video client player and a server hosting a web application.
(FR) La présente invention concerne un procédé de synchronisation de la lecture d'un fichier audio avec la lecture d'un fichier vidéo associé, et en particulier un procédé de synchronisation d'une vidéo et d'un fichier audio qui sont reproduits simultanément par un lecteur vidéo client et un lecteur audio client, respectivement, au moyen du calcul d'une position de lecture audio avec des signaux de position de lecture vidéo et des signaux d'horodatage reçus en provenance du lecteur vidéo client et d'un serveur hébergeant une application web.
