Abstract: The invention relates to the generation of an on-screen display and a control system for the same which allows the known problems in display which can occur to be avoided. Upon change of at least part of an OSD, the system continues until a request to redraw the display is received. At this stage, if the Vsync signal of the display screen has occurred since the change the redraw occurs immediately, thereby avoiding unnecessary delay.
