Trishool, thanks for the information.
I will modify the unviversal de*scram*bler into simple video inversion function. I found this circuit before, but want more simple circuit for only video inversion. Anyway, Thank you.

Pharaoh of Egypt, Thank you for the great link. I think the video inverter from Electronics Now is most simple circuit. I will try it.
