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 microcomputer 9, 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.

Abstract: A system and method for controlling a video display blanking signal so as to maintain a full display screen while minimizing interference with the displayed picture. To control the blanking signal one or more photosensors are placed at the periphery of the display screen. When a CRT overscans the screen at a sensor's location, the light from the CRT is incident on the sensor and the sensor generates a signal proportional to the amount of incident light. The sensor signal is used to adjust the CRT scan such that the CRT scan covers the screen but does not degrade the displayed picture.

Abstract: Items related to the quality of an on-screen image such as brightness, sharpness, chroma, etc. and items related to the audio quality such as bass, treble, balance, etc. in a CRT display, such as a television receiver, are subject to adjustment by a user. These items are originally classified into those in a first class and those in a second class in accordance with the nature of a respective item, that is, whether a user must know the current analog value of the item before he or she adjusts it. When an instruction is input through user's manipulation to adjust the analog value of an item to be controlled, the system determines whether the item belongs to the first class or the second class. If it belongs to the first class, the system first confirms that the item and its actual analog value are displayed on a screen, then permits adjustment of the analog value in response to the instruction, and then displays a new analog value.
