A "red-green-blue" cable. The best analog
video cable. A three-pronged cable that separates the chrominance (color) signal
into a basic blue color stream and a basic red color stream, each with its own
prong. The basic creen color stream is interpreted from the "missing" part of
the video signal. The third prong is dedicated to the luminance ( black and
white contrast / brightness) signal. Gives the purest analog video signal from
the source to display. Uses RCA connections and is the only analog cable to work
with progressive scan features.
