Title
(EN) SYNCHRONIZED PLAYBACK OF STREAMED AUDIO CONTENT BY MULTIPLE INTERNET-CAPABLE PORTABLE DEVICES
(FR) LECTURE SYNCHRONISÉE DE CONTENU AUDIO DIFFUSÉ EN CONTINU PAR DE MULTIPLES DISPOSITIFS PORTABLES AYANT ACCÈS À L'INTERNET
Abstract
(EN)
Playback of an audio stream is synchronized on multiple connected digital devices by using synchronization fingerprints. Playback actions may furthermore be synchronized on all devices, such as skips and pauses. Furthermore, synchronization may be maintained even in the presence of variations in decoding speed, playback interruptions, and network disconnections. Synchronized playback of streamed audio content on multiple devices is achieved by devices compensating for time drifting induced by network instability and variable playback speed across master and guest devices to reduce the formation of echoes during playback.
(FR)
L'invention concerne la lecture d'un flux audio qui est synchronisée sur de multiples dispositifs numériques connectés au moyen d'empreintes digitales de synchronisation. Des actions de lecture peuvent en outre être synchronisées sur tous les dispositifs, telles que des sauts et des pauses. En outre, la synchronisation peut être maintenue même en présence de variations de vitesse de décodage, d'interruptions de lecture et de déconnexions du réseau. La lecture synchronisée de contenu audio diffusé en continu sur de multiples dispositifs est obtenue par des dispositifs qui compensent la dérive temporelle induite par l'instabilité du réseau, ainsi qu'une vitesse de lecture variable, à l'aide de dispositifs maître et invité pour réduire la formation d'échos pendant la lecture.
