Designing RF remote controls for DTV products Design How-To 9/26/2007 Post a comment In the short history of television remote control units, several different schemes have been tried. Early examples from the 1950s used wires, a single beam of light and ultrasonic sound to change channels and control the volume. These have obvious limitations. For instance, the photoelectric cells in the light beam example couldn't tell the difference between a flash light, an ordinary table lamp or even sunlight. This could lead to some chaotic television viewing.
