Which is better ,Component(Red Green Blue) or (Pr,Pc,Y) cables for connecting a DVD to an LCD TV?

I have a Sony LCD TV and DVD with both i/p's and O/p's at both ends.I know HDMI is best but my DVD has no HD O/p.

RGB and Y,Pr,Pb are both component video. Both can give equivalent quality. Neither is inherently better. Y,Pr,Pb is derived from RGB merely by adding and subtracting signals. Essentially Y = R+B+G, Pr = R-Y, Pb = B-Y. (I left out some coefficients for simplicity of explanation.) The tv set will take The Y,Pr,Pb signals and convert them to RGB internally merely by doing the proper summing. But all of the signals have the same information.

RGB is usually outputted on a 15-pin rectangular VGA-type connector, while the Y,Pr,Pb are on three separate cables. I have not yet seen a DVD player with RGB output, so I suspect the only choice you have is Y,Pr,Pb.

To add to the confusion, the cables for Y,Pr,Pb are colored Green Red and Blue, respectively, even thought they don't carry green red and blue signals as such Component RGB is best Pr,Pc,Y is much better For video, the best quality for highest to lowest is componet, s-video, and RFU. I always thought that s-video was better till i read otherwise in my A+ certified book. Supposedly componet is always the best way to go, and it works best going directly to tv, without also going through vcrs and recievers. component comes in different formats.

here's from crappy to best:

YUV 2 signal luminance and chrominance PAL

YIQ also luma chroma NTSC
