Closed captions are captions that are hidden in the video signal, invisible without a special decoder. The place they are hidden is called line 21 of the vertical blanking interval (VBI). A law in the United States called the Television Decoder Circuitry Act of 1990 mandates since July 1993, that all televisions manufactured for sale in the U.S. must contain a built-in caption decoder if the picture tube is 13" or larger.
