ABSTRACT:
A system and a method are provided for conversion of a display of a computer monitor from VGA signals to NTSC signals for display on a television screen. The system implements a circuit which reduces flicker in the output of the NTSC screen. The system includes an input device for inputting a signal in an identifiable mode to stored non-interlaced data relating to the VGA image signals in field memory areas. The VGA image signals are converted in the field memory areas stored to interlaced NTSC image signals. A controller controls the storage and conversion of the VGA signals to NTSC image signals in field memory areas to produce an output.
