component video

« BACK TO DICTIONARY INDEX

(n.) A video signal in which the chrominance (color) and the luminance (brightness) components have been recorded separately. The result is better picture quality. S-VHS and Hi-8 offer two-part component, or Y/C. This format offers higher resolution than composite video (which mixes the Y and C components), because it yields increased bandwidth in the luminance portion of the signal. Color-under, or limited color bandwidth, is a process used in Y/C. The common betacam component system further divides color into three components (Y, R-Y, B-Y), which provide better luminance and color accuracy, and lower noise than Y/C.
