Abstract: A method to synchronize file sharing in a video conference includes periodically labelling each video stream or document sharing stream with a session identifier (ID) to synchronize the conference video streams; periodically reporting to a server the session ID being streamed to the client, and comparing a received session ID with a session ID uploaded by the host client and sending a correct session ID to a client whose session ID exceeds a pre-determined synchronization tolerance.
