Abstract

A technique for synchronizing video receivers with a video stream already in progress includes caching a key frame in a transport protocol component of a video communication system and providing the key frame on demand to any receiver attempting to join the stream and/or to rejoin the stream after an error, such as a dropped packet. Once a receiver obtains the key frame, the receiver requests that the source of the video stream issue a new sync-point frame, where the sync-point frame depends on the key frame but on no other frame for its content. The receiver may then proceed to display rendered video beginning with the sync-point frame.
