摘要

method, apparatus and system for rapid acquisition of multicast real-time transport protocol sessions. A method, apparatus and system for rapidly acquiring real-time multicast (multi-address) transport protocol sessions are provided. The method comprises the following steps, performed by a unicast (single addressing) server: receiving multicast (multiple addressing) fast takeover control request signaling from a media client, where the control request signal contains request information synchronization; determine synchronization of media client data according to the synchronization request information in the signaling according to the time difference between a stored random access point's retroactive runtime and the retroactive runtime and retroactive runtime of the unicast media stream (single addressing); generating multicast quick acquisition control response signaling, wherein the control response signaling contains synchronization response information and multicast acquisition information; Addressing control response signaling and the slower media stream can rerun late media stream with a faster retroactive rerun rate, and therefore, the retroactive video execution figure synchronization can be achieved between different media clients.
