Abstract: Provided are a fast channel change apparatus based on multiple multicasts communication in an IPTV network, and a method thereof. In the fast channel change system, after separately generating at least one multicast stream obtained by applying different time delays respectively to original multicast stream to be broadcast, a channel server dynamically analyzes information regarding the at least one multicast stream. After querying the channel server for information regarding an optimal multicast stream and receiving the response to the query, a user terminal joins a multicast group on the optimal multicast stream through a router. After a predetermined time is elapsed, the user terminal joins a multicast group of the original multicast stream. Thus, it is possible to easily and inexpensively embody a fast channel change function network based on multiple multicasts communication in an IPTV network.
