Abstract

A video display system has a circuit for sequentially superimposing N (N≧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.

Claims

1. 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≧

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.

2. A video display system according to claim 1, wherein said position control means includes means for selecting said display positions, whereby when said N display information signals are all displayed on said picture screen, said N information signals are each displayed at predetermined positions of said picture screen, respectively.

3. A video display system according to claim 1, wherein said position control means includes means for selecting said display positions whereby when other information is additively displayed on said picture screen during the state in which one information signal is displayed, both information signals are displayed on said picture screen at predetermined positions.

4. A video display system according to claim 1, having a built-in video tape recorder with a clock and a timer for stopping a given operation of said system after a preset interval of sleep time, said system control means being connected to receive signals from said video tape recorder, said clock and said timer, whereby when there are 3 display information signals, said display information signals correspond to a tape count value, a sleep time value corresponding to remaining sleep time and a present time.

5. A video display system according to claim 4, wherein said three display information signals are displayed from the corner of said picture screen in the sequential order of said present time, said sleep time value information signal and said tape count value.

6. 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.

7. The method according to claim 6, including the steps of;

displaying information signals at said first location whenever one or more of said information signals are to be displayed, and

displaying information signals at a nonadjacent location spaced from said first location only when at least three of said information signals are to be displayed.

8. The method according to claim 6, including the steps of;

displaying a first information signal at said first location when said first information signal is to be displayed,

displaying a second information signal at said first location when said first information signal is not to be displayed and otherwise displaying said second information signal at a second location adjacent o said first location, and

displaying a third information signal at a third location adjacent to said second location when both said first and second information signals are to be displayed and at said second location when only one of said first and second signals are to be displayed and otherwise at said first location.

9. The method according to claim 6, wherein said video system includes a video tape recorder with a clock and a timer for stopping a given operation of said system after a preset interval of sleep time, including the steps of displaying information signals corresponding to a tape count value, a value corresponding to remaining sleep time and a present time.

10. The method according to claim 9, wherein said information signals are displayed in adjacent locations in the order, beginning with said first location, of said present time, said remaining sleep time and said tape count value.

11. The method according to claim 10, including the steps of initially displaying an image corresponding to said count value information signal including text and numbers and, after a predetermined interval, displaying an image with said numbers only.

12. The method according to claim 10, including the steps of initially displaying an image corresponding to said present time information signal including text and numbers and, after a predetermined interval, displaying an image which is composed of only said numbers and a symbol.

13. The method according to claim 10, including the steps of initially displaying an image corresponding to said remaining sleep time including text and numbers designating the remaining time and the present time and, after a predetermined interval, ending the display of said remaining time and ending the display of said present time unless said present time was already being displayed, and in that case displaying an image corresponding to said present time which is composed of only said numbers and a symbol.
