A flow control based synchronization of media playback of the same media content is provided on all client devices participating in the same broadcast. Each downstream client device participating in the broadcast will independently display the same location in the media at the same time. The broadcaster device requests each downstream participant device in the broadcast to independently downstream the same recorded media, and the central controller will synchronize the media playback so that all downstream devices playback the media at the same location or frame as specified by the broadcaster. For the 3rd party source, a 3rd Party Media Manager control's the play of a playback media. The playback of the playback media at each of the downstream devices is further synchronized with the stream from the broadcaster device using a synchronization marker integrated into the broadcaster device stream.
