Don't want to get lost on a tangent here of asking if every cable on the Internet works but... it was only $4.86 on:
http://www.nugadgets.com/products/ProductDetails/4.1294.1.html The product description on Steren's site 'says' it will do SVGA RGB to (Y, Pr, Pb), (Y, Cr, Cb) standards and RGB high resolution standards. I opted for the RCA 5 connector model to connect to my Mitsubishi HD that has the RGBHV ports on it's DTV input. Avsforums said some people are using this cable but some users mentioned that the color is a little better with a different more expensive brand. http://200.78.227.133/ Steren 253-606IV 6´ Python HDTV SVGA to 5 RCA Python™ HDTV SVGA Component Video Cables Unparalleled Quality and Performance for High-Definition Video and Audio Equipment Fully support (Y, Pr, Pb), (Y, Cr, Cb) and RGB high resolution standards Precision 75˝ Impedance for Max.

That cable is no different from BNC breakout cables that provide RGBHV... just that it has RCA ends on it and relies on the Green signal to be the Y (and have composite sync on it). I did a little 'net research this morning and concluded the following: - EIA 770.1 and 770.2 define 480i and 480p analog component signals. I'm pretty sure that they allow unipolar sync signals like standard video. - EIA 770.3 (and SMPTE-274M) define HDTV analog component. Colorspace is *slightly* different, and the sync is definately defined to be bipolar. Basically, you could use one of those cables to get component out of RGB if it'll do sync on green. Most vid cards that do sync on green are unipolar, I think, so it'd be abusing the spec. It might work on some TV's and not others. What you really want is a vid card that is smart enough to tell the computer it's doing Xv colorspace transformation, to get the YUV data... then not actually do it and barf out the YPbPr the three DACs. The sync should also be correct. In other words... not likely. ************************************************************************* * Cory Papenfuss * * Electrical Engineering candidate Ph.D. graduate student * * Virginia Polytechnic Institute and State University * ************************************************************************* _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
