摘要：
本发明实施例公开了一种频道切换方法、装置和系统，该方法包括：缓存直播频道的组播因特网协议IP报文；接收客户端发送的切换到所述直播频道的频道切换请求，向所述客户端推送所述缓存的组播IP报文；判断所述推送的组播IP报文与所述直播频道的实时组播IP报文是否同步，如果所述推送的组播IP报文与所述实时组播IP报文同步，则停止向所述客户端推送所述缓存的组播IP报文，将所述实时组播IP报文发送到所述客户端。本发明实施例无需改造用户终端，提高了频道切换方案的普适性和可扩展性。
摘要（英）：

The implementation of the invention discloses a channel switching over method, device and system. The method includes that: multicast Internet protocol IP message of live broadcast channel is cached; a channel switching over request which is sent by a client for switching over to the live broadcast is received, and the cached multicast IP message is pushed to the client; whether the pushed multicast IP message is synchronous with the real time multicast IP message of the live broadcast channel is judged, if yes, pushing of the cached multicast IP message to the client is stopped, and the real time multicast IP message is sent to the client. The implementation of the invention requires no modification on client and improves the universality and expandability of the channel switching over scheme.
