Abstract
Provided are a method, an apparatus, and a system for rapid acquisition of multicast realtime transport protocol sessions. The method comprises the following steps executed by a unicast server: receiving multicast rapid acquisition control request signalling sent by a media client, wherein the control request signaling contains synchronization request information; determining data synchronization of the media client according to the synchronization request information in the control request signaling; determining synchronization response information according to the time difference between play time of a stored random access point and the current time, wherein the synchronization response information contains play speed information and play duration of unicast media stream; generating multicast rapid acquisition control response signaling, wherein the control response signaling contains synchronization response information and multicast acquisition information; unicasting the control response signaling and stored media stream to the media client. With the invention, the media client that lags more can play lagged media stream with a faster play speed and thus synchronization of video play picture between different media clients can be achieved.
