PURPOSE: A method for changing a channel is provided, which stores the preferred channel and approaches easily to the preferred channel. CONSTITUTION: Whether a channel change signal is inputted from the former channel change signal within the designated time is determined(S52). In case the channel change signal is inputted after the progress of the designated time, channel is presently changed to the preferred channel of the first priority(S55). If channel is one among the preferred channel, whether the channel is the preferred channel of the last order among the preferred channel is determined(S53,S54). If the channel is presently not the preferred channel of the last order, the channel is presently changed into the preferred channel of the next rank(S57).
