VIDEO SYSTEM WITH SELECTIVELY DISABLED ON-SCREEN CHARACTER DISPLAY SYSTEM |
摘要 |
<p>A television receiver includes a character generator for permitting kinescope display of auxiliary characters in addition to display of normal video signal information, and means for sensing a given characteristic (e.g., bias) of video signal processing circuits of the receiver during prescribed sensing intervals. The character generator is disabled during the sensing intervals to prevent false outputs from the character generator from distorting the characteristic being sensed.</p> |
