摘要：A channel switching method, a channel switching device, and a channel switchingsystem are provided. The method includes that: a network buffer apparatus determineswhether a buffered video stream burst in unicast is synchronous with a channel videostream pushed by a network node to a client in multicast; notifies the client of sending arequest for joining a multicast group, so as to implement fast channel switching; anddynamically adjusts the speed of pushing the video stream in unicast, so that the numberof concurrent connections of the client and the channel switching efficiency are increased,and the deployment and operation cost of an Internet Protocol Television (IPTV) systemis decreased. In this case, the channel switching scheme achieves universality andexpandability, and the level of user experience is improved.
