output/input denotes symmetrical links up/down denotes links to/from the TV set ^ a rarely supported. ^ b non-standard extension. ^ c from STB to VCR when used for unattended recording; 12V forces tv-set to AV-channel ^ d protocol not standardised, e.g. D²B. ^ e This pin is part of the shell/surround of the male connector. It is often connected to the overall screen in a cheap cable. In equipment, Pin 21 should be connected separately to the chassis, but often it is merely connected to all the other ground pins.

SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs – Radio and Television Receiver Manufacturers' Association) is a French-originated standard and associated 21-pin connector for connecting audio-visual (AV) equipment.

It is also known as Péritel (or Peritelevision) (especially in France), 21-pin EuroSCART (Sharp's marketing term in Asia), Euroconector,EuroAV or EXT. In America, another name is EIA Multiport (an EIA interface).

In Europe, SCART used to be the most common method of connecting AV equipment, and was a standard connector for such devices; it was far less common elsewhere. As it was designed to carry analog standard-definition content, SCART has become obsolete with the introduction of new digital standards such as HDMI and DisplayPort, which can carry high-definition content and multichannel audio, though it remains commonly used. HDMI-CEC is derived from SCART's AV.link. However, SCART Connection can also support HD signals like 480p, 720p, 1080i, 1080p, if the SCART connection of a device is designed to support YPbPr connection, but this configuration is rare. The same for multichannel audio, but even this configuration remains rare, as it is not standardized .
