A previous channel changing method of a digital television is provided to enhance the user's convenience by enabling the current channel to be changed to a channel stored in a previous channel list. A microcomputer determines whether the previous channel key is inputted(S10), and then extracts a channel which a user previously watched a moment ago from a previous channel list(S20). Whether the previous channel key is re-inputted before a setting time passes(S30,S40). If so, the microcomputer extracts a channel stored before the currently selected channel from channels stored in the previous channel list(S50). |
