Abstract:

To solve the bandwidth insufficiency of live streaming media's transmission in the Internet, and the diversity of users' access, the general transmission control technologies of streaming media in the IP networks are probed, and a realtime transmission control strategy of streaming media based on broadcast is proposed. The streaming media’s realtime transmission is realized through the multicast and RTP/RTCP agreement. In order to adapt to the dynamic change of network bandwidth, the monitoring of network conditions and realtime streaming switching control are realized by the multithread technology.
