Abstract
A video display system has a circuit for sequentially superimposing N (N.gtoreq.2) information signals upon a video signal for display on the picture screen of a television receiver, at predetermined positions in parallel relation, and a circuit for changing the display positions so as to display information signals sequentially from a corner of the picture screen.
Claims13
A video display system having a picture screen, adapted to display a picture corresponding to a video signal and system control means for controlling said system, said system control comprising, in combination:
- (a) means for generating plural condition information signals, each corresponding to an operating condition of said system;
- (b) superimposing means for sequentially superimposing up to N (N.gtoreq.2) of said condition information signals upon said picture of said video signal displayed on said picture screen such that said N information signals are sequentially displayed so as to be simultaneously visable at predetermined positions of said picture screen in parallel relation to one another;
- and
- (c) position control means connected to said system control means for altering the display positions of certain ones of said N condition information signals if the number of display information signals is smaller than N, whereby said certain ones of said N display information signals is displayed in the spaced immediately adjacent a corner of said picture screen.
A method of displaying a plurality of condition information signals on a video system incorporating a viewing screen for displaying a picture corresponding to a video signal upon which are superimposed a plurality of images corresponding to said information signals, comprising the steps of;
- determining from input commands the condition information signals to be displayed, corresponding to predetermined operation conditions of said video system;
- displaying an image corresponding to one of the information signals to be displayed at a first location in a corner of said viewing screen, and
- displaying images corresponding to all others of said information signals to be displayed at locations adjacent to and in parallel with said first location.
