Favorable visual appearance and ease of operation are required in the user interface of digital home appliances using a television screen. An array of function icons including multiple function icons representing respective playing functions and an array of content icons including multiple content icons representing items of contents that can be played are displayed practically at the center of an on-screen menu such that the arrays intersect. A moving image icon, which is a function icon displayed in an area of intersection in which the array of function icons and the array of content icons intersect, is highlighted by a color different from that of the other function icons and by an enlarged view. An icon in focus immediately below the moving image icon is also displayed in an expanded view. If an external appliance is connected via a network, contents in the external appliance are also displayed in the array of content icons.
