A SCART refers to a special audio and video interface, which is developed by French company Peritel, audio-visual equipment interconnect industry standard) is also mandatory in Europe for satellite TV receivers, TV, VCR and other audio and video equipmentinterconnection interface on the market outside of Europe is difficult to see with this interface device, the TV standard in China is a reference to the European standard-setting is relatively simple. The interface definition is limited to the RF interface, the AV terminals, although to meet the basic needs of most users, compared with S the CART interface transmit signal or some gaps.

With the emergence of new technologies, diversification of development of the audio and video products, and a SCART standard new adjustments, defined specifically for RGB signals, terminals and other multi-specification. S for example, is now widely used in the European market a VCR (video recorder) with the terminals of the S-VHS Y / C signal, you need to deal with, instead of CVBS and RGB signals, so the SCART pin made ??to increase the multiplexing function, remove the definition of the original SCART G, B signals, the direct transmission of C signal by reason of the R signal pathway, while the Y signal is replaced by the CVBS signal transmission. As the saying goes: Sparrow with small, perfectly formed, little SCART actually have such a powerful role, and the connection is so simple, then only one line can really convenient! With a common interface, even if the renewal of equipment, as long as the interface does not update, can be used directly. In contrast, we now use audio and video equipment, the interface a lot, mated to the AV cable with a mess, like spider web, if we can develop a similar SCART interface standards like. I wish this day to come sooner.
