Position
The user can adjust the P-in-P window position by adjusting values of
X
,
Y
and
SIZE
, where X is the
horizontal position, Y is the vertical position and Size is the P-in-P window size.
X-Value
Positive value: position the P-in-P window to the right.
Negative value: position the P-in-P window to the left.
Zero value: Position the P-in-P window at the center.
Y-Value
Positive value: move the P-in-P window up.
Negative value: move the P-in-P window down.

Size
Ranges from 0 to 100 with 1% being the smallest and 100 being the largest. So 50% would
represent a P-in-P window which is half the size of the background image. 100% would see
the PIP image totally cover the background image unless offset to one side.
