A signal processing unit (11) displays a menu included in AV data on a display (4), when a button included in the menu is selected through a user operation to a touch panel (5), the signal processing unit (11) executes the operation process of the button, and returns a state of the menu to a state before the button is selected if a state where the button is selected continues after the execution. By this means, it is possible to improve usability when a dummy button is selected through operation to the touch panel.
