Abstract

PROBLEM TO BE SOLVED: To improve the operability by using operation buttons in common while the minimum number of window switching buttons is provided even when the number of operation windows is increased and selecting a menu pattern being an operation object automatically when no operation is imposed for a prescribed time. SOLUTION: A selection means 5 selects a display information signal 33b as a 2nd selection signal output 5c based on a menu selection signal 5a selected by a menu selection button and does not select a 2nd selection output signal 5b. A deflection means 8 applies deflection processing to the selected signal to provide an output of a synthesis video signal 8b, then the operation content is displayed on a menu 2. In the case of operation of a menu 1, a common menu selection button is switched and similarly the menu 1 is displayed. When no operation of remote control is made for a prescribed time, the menu 1 is restored for selection automatically, the signal 33b superimposed on the video signal of the menu 2 is lost and undesired image display is automatically lost and the menu 1 is an operation object for a succeeding remote control operation. Thus, 2-split screen indication offering ease of use is attained.

However, in the above configuration, when the number of screen divisions increases, it is necessary to arrange the operation buttons corresponding to each screen in the operation device, and the operation system is operated in the multi-screen display system. However, there is a problem in that the size of the operating device becomes too large in consideration of the actual operability.

In view of the above problems, the present invention is an image that can be realized with a size that does not change from the conventional size without significantly deteriorating the operability of the operating device even when the number of screen divisions increases. An object of the present invention is to provide a signal display device.
