Some body explain what RGB and SCART are? Here in the States all we have is RF, A/V, and S-Video, the new one s high defention port but i haven't seen them yet.
SCART is a nominally European connector standard for television sets. It carries RGB, composite video, S-Video, and left/right audio all on a single connector standard. I'd imagine that this is absurdly convenient on several levels compared to the connector soup that US consumers have to put up with.
RGB is more or less equivalent in quality to the "component video" (i.e. color difference video) connections used by DVD players in the US. Color difference video is slightly more convenient for DVD players, because MPEG-2 streams natively decode to a color difference format, but RGB is considered to be the gold standard for most other types of display generation. Arcade monitors typically take RGB inputs, as do most modern computer monitors (standard VGA / Super VGA outputs are RGB). Virtually all color displays use RGB internally to drive the electron beams.
RGB stands for "Red Green Blue", and refers to the primary colors that trigger the human visual system. The signal consists of a level for each of these colors; when combined, they can make virtually any color that humans can see.
Color difference video is convenient for compression applications. Instead of treating the image as a composite of the primary colors, it's encoded as a black & white signal plus signals that describe how biased the image is toward red and blue (green is reconstructed from the brightness). Since brightness is much more important than color to perceived image quality, this actually works rather well, and allows compression schemes to throw away more color data than brightness data. It's one step closer to S-Video, but since the signals are derived with simple mathematical operations instead of having to be combined/separated on each end, the quality loss is negligible.
