I have been looking for a simple adapter to convert
a 480i component YPbPr signal to a 480i composite
or S-Video signal. No other formats are involved,
Composite is a black and white signal with sync, plus the color information modulated on top of it at 4.58 mHz.
If I understand correctly, an oversimplification (which means this task is harder than it looks) is that Analog Component video is
(Y) the instantaneous green signal level plus the sync signals;
(Pb) a signal that is the instantaneous blue signal level minus the instantaneous green level; and
(Pr) the instantaneous red level minus the instantaneous green level.
These signals are processed to extract the green, blue, and red signals.
To begin with, that color information in a composite video signal is a combination of all three colors. That just does not exist anywhere in the component signal.
No, there's no simple way to do what you ask.
Since there is no simple way to change a signal from component to composite, maybe you should back up one step.
Why do you want to do this? What are you trying to accomplish? What components are involved? Model numbers and such will sometimes suggest answers to some of us much better than the generic question.
