A state-setting changing apparatus for a television receiver allows a user to easily change the aspect ratio of a picture displayed on the display screen or make other settings without the need for additional operation keys or dedicated keys on a remote controller and without displaying a setup screen or the like on the display screen. The remote controller includes a specific key for a user to operate at least when making a state setting change, numeric keys assigned to predetermined state settings, and an enter key for a user to confirm a command. The television receiver includes a receiving circuit for receiving signals transmitted from the remote controller, a command analyzing circuit for analyzing a command entered by a user based on contents and an order of received signals, an on-screen display circuit for displaying the number of a numeric key operated by a user on the display screen, and a state-setting changing circuit for changing a state setting based on an analysis provided by the command analyzing circuit when a user operates the enter key.
