Abstract
In a method for picture-in-picture insertion, successive frames of a small picture to be inserted into a main picture having successive frames are alternatingly written frame-wise into a memory region of a memory device. A decision signal is generated at a beginning of a display of the main picture, for deciding from which of the two memory regions a stored frame of the small picture is to be read out. Frames of the small picture are read out from whichever memory region enables joint-line-free insertion of the small picture into the main picture.
