Procédé et système de synchronisation de flux audio et vidéo dans une conférence de relais multimédia

摘要

A novel technique allows synchronizing a plurality of audio and video streams received at a receiving media relay endpoint (130) via an intermediate node (120), such as a media relay multipoint control unit. The received streams were generated by a plurality of transmitting media relay endpoints (130) and been relayed to the plurality of receiving media relay endpoints (130) via the intermediate node (120), but are seen as being using a single time domain, in terms of wall clock and manipulated timestamps, while preserving the correct capture time.
