Abstract
A television display reduces the visibility of the raster-scan structure. Each incoming horizontal line of video information is stored in a memory and read twice at a double clock frequency. Each incoming horizontal line is therefore replicated. Each line and its delayed replica are applied to a display device scanned at double the normal rate, thereby displaying each horizontal line of information as a line pair oriented one above the other. This doubles the number of scanning lines in the display in a simple manner and reduces the visibility of the raster scan structure.
