S-Video (Hosiden, Y/C)

S-Video connector

Separate lines for brightness (Y, luminance with synchronization data) and color (C, chrominance) via a 4-pin Hosiden connector. By separating luminance and color signals, better image quality is delivered when compared to composite video (FBAS) connections. In the realm of analog image signals, HDTV Components represent the best connection type followed by S-Video. Only pure digital signals such as DVI (via TDMS) or HDMI (via TDMS) offer a better picture, and represent today's optimum choices.
