A set-top box (STB) or set-top unit (STU) is an information appliance device that generally contains a tuner and connects to a television set and an external source of signal, turning the source signal into content in a form that can then be displayed on the television screen or other display device. Set-top boxes can also enhance source signal quality. They are used in cable television and satellite television systems, as well as other uses.
