Title (EN) SYSTEM AND METHOD TO ASSIST SYNCHRONIZATION OF DISTRIBUTED PLAY OUT OF CONTROL
(FR) SYSTÈME ET PROCÉDÉ D'AIDE À LA SYNCHRONISATION DE RESTITUTION RÉPARTIE DE CONTENU
Abstract:
(EN) A method for synchronizing content undergoing play out at first and second stations commences by comparing audio within content undergoing play out on the first station to the audio within content undergoing play out on the second station to determine if a latency exists between the first and second stations. If such a latency exists, then at least one of a pause or jump operations is performed in connection with content playing out by at least one of the first and second stations for an interval corresponding to an interval by which one station leads the other station to bring the two stations into substantial synchronism
(FR) L'invention concerne un procédé de synchronisation d'un contenu faisant l'objet d'une restitution au niveau d'une première et d'une deuxième station, ledit procédé commençant par une étape consistant à comparer l'audio figurant dans le contenu faisant l'objet d'une restitution sur la première station avec l'audio figurant dans le contenu faisant l'objet d'une restitution sur la deuxième station pour déterminer s'il existe une latence entre les première et deuxième stations. S'il existe une telle latence, alors au moins une opération parmi une pause et un saut est effectuée en liaison avec le contenu en cours de restitution par au moins une des première et deuxième stations pendant un intervalle correspondant à un intervalle d'avance de l'une des stations par rapport à l'autre station, pour amener les deux stations à être sensiblement synchrones.
