Abstract: A system and method for generating and distributing overlay streams in real time over an overlay stream distribution channel that overlays events of a video stream distributed in a separate video channel. Overlay streams are distributed to subscriber recipient components via a unicast channel in order to enhance user viewing. A publisher subscriber component and caching techniques a low latency, high availability unicasting based real time overlay distribution system for a large numbers of concurrent overlay recipients.
