The SCART (Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) connector is that horribly designed rectangular connector that's always falling out of the back of the TV. It is used for combined audio and video connections between TV, DVD/Video recorders, receivers and many other combined audio/video devices. It is also known as Peritel connector or Euroconnector.
There are different pin-configurations available depending on the video device used.
Apart from the audio and video connections there are also two status signals which partly define which video signals are active. A video device can use these status signals to automatically switch between internal or external audio/video signals. For example turining on your DVD player may put +5V on pin 8 causing the TV to switch from normal reception to the DVD.
