Abstract
Provided are a channel server, a channel prediction server, a terminal, and a method for a fast channel switching. The channel server may generate at least one delay multicast stream from an original multicast stream by applying a different delay value based on channel preference information, and may determine an optimal multicast stream from the at least one delay multicast stream, and transmit, to a terminal, response information associated with the optimal multicast stream in response to query information associated with the original multicast stream received from the terminal.
