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

Notes
- EasyLink enables bi-directional communication between a
television set and a video recorder. This way a video recorder can,
for example, copy the channel settings of the television set.
