i did work with the AD725 at some points in time , but i still cant quite grasp how it exactly works .
the signal i use often shows up differently of different TVs , though what is the brute signal form exptected by chips like the AD725 ? or does it work with that signal no matter how corrupted it is ? then get the same output i would have on that monitor on grayscale but with color ?
i did read some of the datasheet btw , it says "chip will assert the color burst at the time of the back-porch after the sync" so no matter how crappy the signal is , the chip always inserts a color burst ? how ?.
