Intarea S-Video ajunge DUPA decodorul de culoare (deci calitate ceva mai buna, luminanta nu este amestecata cu purtatoarea de chrominanta, chrominanta este pura, nu modulata cu 4.43).
Off topic:
Prea multe detalii pot duce la exprimari incorecte...
Nu este corecta afirmatia de mai sus... si semnalul S-Video tot la decodorul de culoare ajunge...
Nu cred ca trebuie sa-ti explic eu tie...
Dar ca idee pentru cititori:

S-Video (also known as Y/C) is a baseband analog video format offering a higher quality signal than composite video, but a lower quality than RGB and component video. This mid-level format divides the signal into two channels—luminance (Y) and chrominance ©.
The luminance signal and modulated chrominance subcarrier information are carried on separate synchronized signal/ground pairs.
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.
While the luminance performance of S-Video compares favorably to analog component video, the chrominance performance—aside from reduced crosstalk—does not show notable improvement over composite video.
