SCART ( fr. Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs - "Association of manufacturers of radio receivers and televisions") is the European standard for connecting multimedia devices such as TV , VCR , DVD-player . Other names: Peritel, Euro connector, Euro-AV.

Application
SCART unifies the connections of different devices, it combines all the necessary signals in one multi-pole plug. Most of the LCD / LED TVs on the market are equipped with at least one SCART connector.
Analog and digital commands can be transmitted via SCART. For example, if you turn on the VCR, the TV automatically turns on. The CEC video control protocol , transmitted via the SCART connector, made it possible to simplify the configuration of various equipment using a single remote control . For example, from a TV remote you can program a VCR to record at a specified time from a satellite or cable digital receiver .
The design of the connector does not allow the plug to connect incorrectly. The disadvantage of the connector is that in order to connect and disconnect it, physical force must be applied.
Development
Before the advent of the SCART standard, a large number of different connectors were used, which often made it difficult to connect devices made by different companies. There were differences both in the physical performance of the connectors and in the signal specifications.
In 1978, the SCART standard was developed in France . Since 1981 in France it was forbidden to sell TVs that are not equipped with a SCART connector. Since 1984, SCART has become the standard in European countries.
