Fun with Component video

Posted by DavidLD on February 23, 2008 at 14:01:18:
I wanted to hook my old DVD player (Toshiba 3950) to the new Panasonic 32 inch flat panel via component video. All I had was a standard red/white/yello audio/ composite video cable I had picked up at the dollar store. So, I decided to make Py = Yellow, Pr = Red and Pb=white. I plugged it in.
Oddly, the DVD picture appears to be absolutely perfect using this cheap cable. I can see no artifacts whatsoever. I wouldnâ€™t do this for a longer run but I did think that this was interesting. If there are any artifacts I should be looking for let me know.

Fun with Component video.
Component video separates the color signal into the three component colors (chroma) as well as the brightness (luma)
Py contains the brightness information and also the information needed to do the green component. If Py is disconnected, the screen will be entirely black. Interestingly, with only Py, the result is a black & white not a green and white picture.
Pb contains the information needed for the blue component. If Py and Pr are connected but Pb is disconnected, flesh tones turn magenta, and the blue sky turns cyan (blue-green) Tan colors will tend toward magenta.
Pr contains the information for the red component. If Py and Pb are connected, but Pr is disconnected, the sky turns purple and faces take on a sickly greenish cast
Swapping Pb and Pr leads to a really strange situation. Faces and flesh tones turn blue, and the sky turns a Martian orange-red
