Abstract

In display apparatuses, particularly television receivers and monitors, a video picture can be inserted into a main picture (HB) from a first video signal (VS1), in which a second picture (ZB) from a second video signal (VS2) has a first picture format and is composed of picture lines (BZ) and filling lines (FZ). The picture lines (BZ) forming a sub-picture (UB) with the second picture format is adjoined by the filling lines (FZ) in the vertical picture direction. The second picture format of the sub-picture (UB) is determined and the determined second picture format is used for determining the filling lines (FZ). The picture lines (BZ) and a portion of the filling lines (FZ) are inserted as an insertion picture into the main picture (HB). Additional insertions (OSD) from an additional signal, which at least partly lie within the filling lines (FZ), is displaced into the sub-picture (UB).
