Component to S-Video for standard-def

When dealing with standard-def video, is it possible to convert a component video signal (three RCA connectors) to S-Video (4-pin DIN connector) without using a converter box?

If so, where can I get the necessary adapter to do this?

The signals are nothing alike. It is unlike in BNC<->RCA conversions, where the video is typically in one format (composite or component), and the connector has little to do with the signal being passed through. In the case of S-Video's DIN connector, it is used almost exclusively with S-Video signals, which do not typically pass through RCA connections.

The separated chroma signals in component video must be multiplexed into S-video by some means, hence the need for a converter.
 
Thanks for explaining that. I didn't realize that signals were multiplexed when converted to s-video.

It was my understanding that s-video is better quality than composite video. I thought that composite video was multiplexed and s-video was separated. Are you saying that composite video and s-video are similar in quality? If not, then what is the difference between those two?

Thanks.
 
Composite is all multiplexed. S-video keeps the luma separate from the chroma, but the chroma components are multiplexed. So it is like halfway between composite and component video.

Thanks guys! Thanks for clearing that up. That makes sense. :)
 
Oh, and one more question regarding component video signals:

Why are the abbreviations for Luminance and Chrominance "Y" and "Pb" and "Pr" (or "Cb" & "Cr" for digital)?

I was only to answer my question halfway, finding that "b" and the "r" were referring to the difference in color values in relation to the luminance value. I am only assuming that "C" stands for Chrominance in regards to digital video. But I still don't know what Y or P stand for.

Thanks for any help!
 
Y = luminance.

Y/Cb/Cr = luminance and component blue and component red (being the difference, B-Y and R-Y) for digital video systems

Y/Pb/Pr = luminance and component blue & red (also B-Y and R-Y) for analog video systems

S-video is also known as YC, which is Y for luminance and C for chrominance (both red and blue combined together into one signal).
 
Sorry, I meant to ask why is Luminance "Y?" Why is it not "L?" (And the same question for "P")
