Set-top Box

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.

Famous quotes containing the word box:

    Franceska: I was happy in the life I built up for myself. I put a fine high wall of music around me and nothing could touch me. I was safe and secure. And then you had to come along and knock it all down and I hate you for that.
    Maxwell: On the contrary, you love me.
    —Muriel Box (b. 1905)
