ABSTRACT:
A video signal of a main screen is supplied from an input terminal (1) through a change-over switch (2) and an RGB drive circuit (3) to an image receiving tube (4). The video signal of a sub screen is also supplied to a sub screen signal production and control circuit (6) through an input terminal, compressed to an arbitrary size, and derived at an arbitrary positional timing to thereby produce the video signal of the sub screen. A command signal from a commanding unit is further supplied to a microcomputer (9) through an input terminal (8). In the microcomputer9, the command signal mentioned above is supplied to a central processing unit (CPU) (10). The central processing unit produces a control signal indicating the displayed position of the sub screen or the like. In a part of the processing, the similarity and/or non-similarity of operation buttons is judged and a response time of the control is determined, whereby the actions can be carried out smoothly.
