Table 4-17 Coarse Positioning
There are 256 horizontal locations (4 pixel increments) and 256 vertical locations (2 line
increments). The pixel width on the screen depends on the selected HZOOM factor.
Even POP-positions (Picture Outside Picture) in 16:9 applications are possible.

Wipe In / Wipe Out
With the wipe in / wipe out function it is possible to let appear or disappear the complete
inset picture starting or ending at the corner of the inset picture position defined by
CPOS. Thereby the size of the visible picture-part is continuously increased and
decreased respectively. During this procedure the frame is shown with its chosen widths.
3 different wipe in / out time periods or ’no wipe’ are programmable via WIPESPD. The
wipe algorithm always works in horizontal and vertical direction.
