Abstract
Systems and techniques are provided for synchronizing playback of a video at a plurality of client-side nodes in a network including a server-side node and the plurality of client-side nodes. The system includes logic to receive a sync video message at the server from a first client-side node identifying a sync event time. The system includes logic to map the sync event time at the server to a sync frame identifier. The server sends a follower sync video message to a follower set of one or more other client-side nodes including the sync frame identifier. In response to the follower sync video message the one or more client-side nodes in the follower set can synchronize playing the video at a frame corresponding to the sync frame identifier.
