Abrégé
(EN)
The present invention relates to a method and device for transceiving an MPEG2 transport stream (TS)-based media file. The method for transceiving includes: mapping the PTS of a presentation unit (PU) for at least one program element constituting a program in a media file into media presentation time (MPT) for synchronization with other media; and transmitting the synchronization information including the mapped MPT together with the media file.
(FR)
La présente invention concerne un procédé et un dispositif permettant de transmettre/recevoir un fichier multimédia basé sur un flux de transport (TS) MPEG2. Le procédé de transmission/réception comprend les étapes suivantes : associer le PTS d'une unité de présentation (PU) pour au moins un élément de programme constituant un programme d'un fichier multimédia à un temps de présentation multimédia (MPT) pour une synchronisation avec d'autres fichiers multimédia ; et transmettre les informations de synchronisation incluant le MPT associé conjointement avec le fichier multimédia.
