METHOD, APPARATUS, AND SYSTEM FOR SWITCHING CHANNELS

摘要

A method, an apparatus and a system for switching channels are disclosed. The method includes: buffering a multicast Internet Protocol (IP) packet of a live channel; receiving a channel switching request sent by a client for switching to the live channel, and pushing the buffered multicast IP packet to the client; and judging whether the pushed multicast IP packet is synchronous to a real-time multicast IP packet of the live channel; and stopping pushing the buffered multicast IP packet to the client and sending the real-time multicast IP packet to the client if the pushed multicast IP packet is synchronous to the real-time multicast IP packet. The embodiments of the present invention involve no modification of the user terminal and improve the universal applicability and extensibility of the channel switching solution.
