13 Picture-in-Picture Plus (PIP
+
)
13.1 Concept
Picture-in-Picture Plus enables a secondary window (or PIP
+
window) within the main
display window. The PIP
+
window may be positioned anywhere within the virtual display
and is controlled through the PIP
+
Window control registers (REG[7Ch] through
REG[91h]). The PIP
+
window retains the same color depth and SwivelView orientation as
the main window.
The following diagram shows an example of a PIP
+
window within a main window and the
registers used to position it.
