In Reply to: S-Video vs. Component Video posted by babcocks on January 02, 2001 at 06:34:50:
S-Video carries luma(Y) and Chroma(C) information.
And is better than the composite Video (CVBS), because color information is carried seperately. But Component video is even better because the TV set does not have to make any further decoding if you give this signal. With S-Video input, the colors should still be decoded.
Follow Ups:
what do you mean by the tv does not have to do any further decoding? please explain in detail
S-video carries a luminance signal and a single chroma signal (all the color information in one signal) A component set of cables carries the 'color' signal in two parts: two "color minus" signals that are the standard way video signals are sent in the television world. A TV would have to 'sort out' the S-vid chroma signal colors, but the component signals were not mixed together in the first place. Component reduces 'dot crawl' and other bad stuff.
by the way, a red,blue, green signal in a TV setup would NOT be better (except if you had a projector, maybe) because the NTSC TV signals are not sent in RGB, they are the COMPONENT set-up straight out of the TV cameras. NTSC uses the two "minus" sets as a way to save bandwidth and are a historical anomaly of the switch from black and white TV to color television.
I understand what you are saying, but I am only looking to use this for my DVD input and not for cable coming in that is on a coax connection from the cable box. But it does seem that in comparison for viewing of DVDs, component is indeed better, due to the fact that the colors are already seperated, leaving the television circuitry less to do, hence having a clearer picture. Yes?
