SCART stands for Syndicat francais des Constructeurs d'Appareils Radio et Television, and refers to the industry standard interface for physical and electrical interconnection between two pieces of audio-visual equipment, originated by the French company Peritel.
A SCART connector is used to connect two electronic devices such as a television set and a video cassette recorder (VCR) or DVD player which has SCART Female inputs / outputs. Each device has a female 21-pin connector interface. A cable with a male plug at each end is used to connect the devices. (The 21st pin is actually not a pin but a ground shield contact.)
Stereo audio, composite video, and control signals are provided in both directions. RGB video signals are INPUT only. Most new television sets and VCRs in the European market and other countries that use the PAL video standard come equipped with one or more SCART connectors.
