CHANNEL SEVER, CHANNEL PREDICTION SERVER, TERMINAL AND METHOD FOR THE FAST CHANNEL CHANGE SYSTEM BASED ON MULTIPLICITY MULTICAST WITH PROGRAM RATING PREDICTION

摘要

PURPOSE: A channel sever, a channel prediction server, a terminal and method for a fast channel change system based on multiplicity multicast with program rating prediction are provided to predict a channel to be changed based on a program rating. CONSTITUTION: Based on channel preference information, a streaming module(111) applies delay values to an original multicast stream. The streaming module generates at least one delay multicast stream. An analysis module(112) receives query information on the original multicast stream from a terminal. The analysis module receives the query information on the original multicast stream, and determines the optimized multicast stream among the delay multicast streams. The analysis module transfers the response information related to the optimized multicasts stream to a terminal(140).
