Picture Positioning
The display position of the inset picture is programmable to the 4 corners of the parent
picture (CPOS). From there PIP can be moved to the middle of the TV Picture with
POSHOR and POSVER. The corner positions can be centered coarsely on the screen
with POSOFH and POSOFV. Depending on coarse position, one PIP corner remains
stable when changing the picture size.
