20120114299DISC REPRODUCTION APPARATUS - A disc reproduction apparatus of the present invention has a signal processing section which displays a pop-up menu and a user interface specific to a title being reproduced by a reproduction section, on a monitor. Upon accepting a user's operation to display the pop-up menu or the user interface, the signal processing section displays only any of the pop-up menu and the user interface on the monitor. Due to such configuration, only any of the pop-up menu and user interface specific to an HDMV mode or BD-J mode title is displayed, and thereby, wrong operations by a user are reduced.05-10-2012
