Driver for picture in picture display using beagle bone

Hello,
Do anyone know about
how to generate picture in picture display using beagle bone black & display it on HDMI?
From where to get drivers?

Please help.

The driver controls the screen. The application controls what goes on the screen. So, what application do you plan top use? Maybe running two instances of the same application, running at the same time in two different windows?
