  • Video switching
    Patent number: 4488180
    Abstract: A video switching method for switching between two video signal sources for display on a monitor is employed by intensity modulating a video signal on a television raster lines and frames. Digital values representing pixel positions on the field when a switch is to occur from one source to another are stored. The representations of the pixels during the generation of the raster are counted and compared with the stored representations to effect switching when a equality between the two representatives occurs.
