The SCART interface
Also known as Peritel, this standard provides a cheap multi-signal connector to
domestic TV and other video equipment.
Arrangement 1 is the original and allows for composite video input/output, RGB
inputs and stereo audio input/output.
Arrangement 2 allows for composite video input/output, RGB inputs and stereo
audio input/output.
Caution: The output of video and audio are always from turner of RF.
Arrangement 3 allows for composite video input and stereo audio input/output.
TV can auto check aspect ratio in SCART.
