Set-Top Box

A “Set-top box” is a generic term for a video receiver, such as a cable, broadband, or satellite receiver, that was originally intended to sit on top of and connect to a TV set (although today’s flat-screen TV’s make this a misnomer). Set-top boxes convert proprietary digital video signals into conventional video (often high-definition) and audio. Since the set-top box tuner replaces the TV set’s built-in tuner, it often requires a separate remote control.
