SCART is a French-originated standard and associated 21-pin connector for connecting audio-visual equipment together. It is also known as Péritel (especially in France) and Euroconnector.

SCART makes it easy to connect AV equipment (including TVs, VCRs, DVD players and games consoles). In essence, it gathers together various common analog signal-types into a single connector. The signals carried by SCART include both composite and RGB video, and stereo audio input/output, as well as support functions. The voltage levels are rather high, around 1V, so the signals have good noise immunity.

Notes

  • Video Output Level : 1 V p-p +/-2 dB
  • Video Output Impedance : 75 ohm
  • Video Frequency Range : 25Hz. - 4.8MHz (+/-1.5 dB)
  • Video De-emphasis(PAL) : to CCIR 405.1 (625 lines)

Many TV sets have 2 SCART sockets. One is usually uses previous pinout table and the other uses following pinout table. The first can switch from a composite input to RGB input. The second can switch from a composite input to an S-Video input, pin 20 being either composite in or luminance in. Usually the second socket outputs a selectable composite signal on pin 19
