SCART is an interface plug,

SCART (from Syndicat des Constructeurs d'Appareils RadiorÃÃâ€*’©ce pteurs et TÃÃâ€*’©lÃÆ ’Ãâ€*’©viseurs) is a French-originated standard and associated 21-pin connector for connecting audio and video equipment to television sets. Also called PÃÃâ€*’©ritel (especially in France, where the SCART word is not normally used) and Euroconnector.

not a transmission standard method, you can transmit RGB, S-Video, Component down it.

Component : component is better than scart, but you need a screen with component inputs.
Coaxial digital: For digital sound from dvd player to amp.

S-Video - from Wiki
The luminance (Y) signal and modulated chrominance (C) subcarrier information are carried on separate synchronized signal/ground pairs. Because of this, S-Video is also considered a component signal.
In composite video, the luminance signal is low-pass filtered to prevent crosstalk between high-frequency luminance information and the color subcarrier. S-Video, however, separates the two, so low-pass filtering is not necessary. This increases bandwidth for the luminance information, and also subdues the color crosstalk problem.
The luminance performance of S-Video is noticeably better than composite video; the chrominance performance with reduced crosstalk also shows noticeable improvement.
also from WIKI
RGB is a type of component video signal used in the video electronics industry. It consists of three signals - red, green and blue - carried on three separate cables. Extra cables are sometimes needed to carry synchronising signals. RGB signal formats are often based on modified versions of the RS-170 and RS-343 standards for monochrome video.
This type of video signal is widely used in Europe since it is the best quality signal that can be carried on the standard SCART connector. Outside Europe, RGB is not very popular as a video signal format †“ S-Video takes that spot in most non-European regions. However, almost all computer monitors around the world use RGB.
Again Component is not better than Scart, Componenet is a method of transmission, as is SCART, you can transmit a component signal down a scart lead (indeed an RGB on a scart is a transmission of a component signal on a scart lead), there is an alternate scart wiring that allows SVideo down a scart lead.
So
SCART, Component Cables are transmision methods, as is Digital audio on Optical or Cable.
RGB, SVideo, Composite, Digital (audio)are all transmission standards.
