Abstract (en)
[origin: WO9426063A1] A subliminal message display system is disclosed which permits the display of a "subliminal message". The display occurs by switching a programme input video signal (91) during a single field of its display to display a subliminal message (92). A retrace (93) of the rasterised display occurs and an erasure signal (94) is used to erase the subliminal message from display. A downward advance (95) of the rasterised display is forced so as to compensate for display time lost in rendering the erasure signal (94). The programme image signal (96) is then re-enabled. A variety of embodiments are described which permit both the rendering and erasure of a subliminal message within a single display field of a rasterised display.
