Glossary -Y-

Y — The luminance or black-and-white part of a video signal.

Y adapter — Used in audio, a Y-shaped connector or wire which combines two signals or splits one signal into two.

Y/(R-Y)/(B-Y) — Pronounced Y, R minus Y, B minus Y, this is one way component video is transported; also the type of video equipment or circuits that handle such signals. The letters represent luminance with sync, red minus the luminance, blue minus the luminance.

Y/688 dub, Y/629 dub — Method of sending separate luminance and downconverted color signals between 3/4U and SVHS and VHS editing-type VCRs to preserve color quality.

Y/C or S — A method of transmitting color video over two wires, one carrying luminance (Y) and the other carrying color (C). Also called super or S-video as it is employed on super VHS (SVHS) VCR’s and camcorders. Hi8 camcorders also use Y/C video.

Y/C or S connector — Multipin connector designed to carry Y/C video on two wires inside one cable.

Y/C — Video signal separated into two parts: brightness (Y) and color (C). Such signals yield sharper, cleaner color than composite video signals. Also another name for S connector.

Y/I/Q — Another form of Y/(R-Y/(B-Y) making component color video using luminance and two color difference signals.

Y/Pb/Pr — Another form of Y/(R-Y)/(B-Y).

Y/U/V — A form of Y/(R-Y)/(B-Y) making component color video, popular in Europe.

Yagi — A type of outdoor TV antenna.
