Abstract: A fast change method for a digital video broadcasting (DVB) channel. 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.

Abstract: The disclosure relates to a message distribution method, device, and system. A message distribution method includes: creating a session based on a received first type of session message and allocating a corresponding cluster node to the session; and upon receiving a second type of session message associated with the session, distributing the second type of session message to the cluster node corresponding to the session. With the technical solution according to the embodiments of the invention, both the first type of session message and the second type of session message may be processed on the same cluster node, smooth and dynamic capacity expansion may be achieved for the cluster, the system performance may be enhanced, and system maintenance may be facilitated.
