2.12.4. Acquisition and Display Window
The acquisition window defines the picture area of the
input active video to be displayed as a inset picture on
the screen.
The display window defines the display position of the
inset picture(s) on the screen.
The acquisition and display windows are controlled by
I
2
C parameters HSTR, VSTR, NPIX and NLIN (see
Fig. 2–25 and 2–26). They indicate the coordinate of
the upper-left corner and the horizontal and vertical
size of the active video area. In VPC
pip
or VPC
single
mode, these four parameters define the acquisition
window in the decimated pixel grid, while in VPC
main
mode they define the display window.

2.12.5. Frame and Background Color
Two programmable frame colors COLFR1 and
COLFR2 are available to high-light a particular inset
picture.
Instead of displaying the main picture it is possible to
fill the background with a programmable color COL-
BGD (set SHOWBGD=1 in the register PIPMODE),
e. g. for multi PIP displays on the full screen (see mode
6 and 10).
COLFR1, COLFR2 and COLBGD are 16 bits wide
each. Therefore 65536 colors are programmable.
2.12.6. Vertical Shift of the Main Picture
The VPC
main
mode supports vertical up-shifting of the
main picture (e. g. letterbox format) to enable bottom
insets (see mode 11). The vertical shift is programma-
ble by VOFFSET.
2.12.7. Free Running Display Mode
In this mode a free running sync raster is generated to
guarantee a stable display in critical cases like tuner
scan. Therefore the LLC should be disabled (see
Table 2–12).
2.12.8. Frame and Field Display Mode
In frame display mode, every field is written into the
field memory. In the field display mode every second
field is written into the field memory. This configuration
is suitable for multi picture insets and freeze mode,
since it avoids motion artifacts. On the other hand, the
frame display mode guarantees maximum vertical and
temporal resolution for animated insets.
In the predefined mode the setting of frame/field mode
is done automatically to achieve the best performance.
