That's component, alright. Three separate cables to complete the video connection. It is generally considered the "best" video connection, superior to S-Video which is in turn superior to composite.

For progressive scan DVD and for HD signals, you need component (or something more exotic -- VGA or a digital connection like DVI). Actually, I should clarify that for those two you need a "special" component input that supports it, slightly different to the typical component video.
