Gus, though I am far from expert ....well on my way to learning less and less about more and more til I know nothing about everything..... I can contribute a tiny bit from general home theatre reading I have done. Video component outputs and inputs separate the three components of a digital video signal ( Y, R-Y, and B-Y) Component video is thus a method of transfer and storage of video information and storage in separate components.( I do not understand the 4th wire unless it is indeed a " clock" element. Will check around.) Today's standard formats - PAL , NTSC, and SECAM - transfer and store "combined" signals which are derived from the three channels of RGB information. An example of one edge of component video output and input is that absolute black is set at 0. So you get about a 10% pop in chiaroscuro dynamic range - which may not sound like much, but light and shadow info has a pronounced effect on the visceral impact on dramatic visual detail. Some high end video equipment nowadays have these component inputs and outputs. Most do not as of yet. I personally would sure welcome any posts from true experts on this matter.
PS..have read that the nature of the video " clock " ( Mitsu litigation) used has substantial effect upon performance in a variety of digital applications. Audio and video.
