Background The Background bus indicates which current background picture is selected.
Pressing another key in this row performs a hard cut to another background picture.
The selected background picture can be checked on the program monitor.
Background Preset The Preset bus serves the preselection and indication of the background picture
involved in the next transition. The background picture and the selected modifica-
tions (e.g. key) can be previewed on the preset monitor.
Background and preset bus operate in the flipflop mode, i.e. after completion of the
running transition, the preset and background sources will change automatically.
Thus, it is clearly shown which signal contributes to the output picture.
The arrangement of background and preset bus can be changed from the interna-
tional mode (preset bus below) to the German mode (background bus below). See
the section Setup.
