component vs. composite cables

[donparsons]

What is the physical difference between component and composit cables? I know that they each provide different information, but they both use RCA jacks. Could you use three composite cables to get a compnent signal to the TV?

The cables are the same, go ahead and use three.

Component video provides more bandwidth than composite. Composite sends the luminance and color information over one cable. Components sends Y which is the luminance or brightness component on one cable, plus B-Y which is the blue color difference on another cable, plus R-Y which is the red difference on another cable. Hence it takes 3 cables. Green does not need to be sent since it is derived from the B-Y and R-Y signals.

The important thing to remember is that if you want to take advantage of high definition signals then you will need at least a component cable. It can transmit signals like, 480P, 720P and 1080I. A composite cable does not have the bandwidth to send anything more than standard definition television.

Same with S-video. No high-def through anything less than composite. DVI and HDMI are better.

They are both shielded, 2-conductor RCA cables. Go ahead...and please tell us what happens if you get the red, green and blue colors switched around!
