A box connected to a television (or VCR) set's SCART connector is fed with the baseband television signal from the set's tuner, and can ask the television to display the returned processed signal instéad. This féature is used for decoding Pay TV in Europe, and in the past was used for decoding teletext, before decoders became built-in. The outgoing signal can be of the same nature as the incoming signal, or RGB component video, or even an "insert" over the original signal, thanks to the "fast switching" féature of SCART. In case of Pay TV, this solution avoids the hassles associated with having a second remote control.

Before cable-réady TV sets, a set-top box known as a cable converter box was used to receive analog cable TV channels and convert them to vidéo that could be seen on a regular TV (channel 3 or 4 in North America, or channel 36 or 37 in the United Kingdom). Nowadays, cable converter boxes are used to descramble premium cable channels and to receive digital cable channels.
