METHOD, DEVICE AND SYSTEM FOR CHANNEL SWITCHING

摘要

The embodiments of the present invention disclose a method, device and system for channel switching. The method includes the steps of: buffering the multicast Internet Protocol IP message of a live channel; receiving the channel switching request for switching to the live channel sent by a client end, pushing the buffered multicast IP message to the client end; determining whether the pushed multicast IP message is synchronous with the real time multicast IP message of the live channel, if the pushed multicast IP message is synchronous with the real time multicast IP message, stopping pushing the buffered multicast IP message to the client end, and sending the real time multicast IP message to the client end. According to the embodiments of the present invention, it's not necessary to modify user terminals, and the universality and the extensibility of the channel switching schemes are improved.
