Abstract

For use in a communications network having a source and destination endpoint that employs a video transmission protocol in which the destination endpoint of a video stream receives a release command from the source endpoint of the video stream to begin displaying the video stream, the destination endpoint normally receiving the release command only after completion of a capabilities negotiation between the destination endpoint and the source endpoint, a system for, and method of, multicasting the video stream from the source endpoint to at least one destination endpoint. The method includes the steps of: (1) beginning the multicasting of the video stream, (2) ignoring any capabilities messages received from the at least one destination endpoint during the multicasting of the video stream and (3) issuing periodic release commands during the multicasting of the video stream irrespective of receipt times of the ignored capabilities messages, the at least one destination endpoint thereby commanded to begin to display the video stream following a simulation of the capabilities negotiation.
