Abstract

L'invention concerne un dispositif de synchronisation d'un flux multimédia constitué de deux flux multimédia distincts dans un réseau de télécommunication constitué d'un réseau de télécommunication synchrone et d'un réseau de télécommunication asynchrone, un desdits flux transitant sur le réseau de télécommunication asynchrone, l'autre flux transitant sur le réseau de télécommunication synchrone, caractérisé en ce que le dispositif comporte des moyens pour obtenir des informations de délai représentatives du délai de transmission du flux transitant sur le réseau asynchrone et des moyens pour modifier le délai de transmission du flux multimédia transitant sur le réseau synchrone à partir des informations de délai obtenues. L'invention concerne aussi le procédé de synchronisation associé.The invention relates to a device for synchronizing a multimedia stream consisting of two distinct multimedia streams in a telecommunications network consisting of a synchronous telecommunications network and an asynchronous telecommunications network, one of said streams passing through the telecommunications network. asynchronous, the other flow passing through the synchronous telecommunications network, characterized in that the device comprises means for obtaining delay information representative of the transmission delay of the flow passing through the asynchronous network and means for modifying the transmission delay of the multimedia stream passing over the synchronous network on the basis of the delay information obtained. The invention also relates to the associated synchronization method.
