A fast channel change (FCC) server is introduced into an existing DVB system architecture, and a unicast transport stream is fast sent to a user equipment in a manner of unicast of the FCC server assisting broadcast. A transport stream (TS) stream and a Real-time Transport Protocol (RTP) stream are synchronized by comparing presentation time stamp (PTS) values of TS streams on a DVB side and an FCC side. In this way, it is ensured that the user equipment fast displays an image, channel change time is reduced, a channel change speed is increased, and user experience is improved.
