1. A visual display system comprising: background image projection means for generating a background image having a predetermined size and resolution; inset image generation means for producing video signals representative of a plurality of inset images; inset image projection means, responsive to said inset image generation means, for generating a plurality of inset images, each having a smaller size and a higher resolution than the background image, in response to the video signals produced by said inset image generation means, said inset image projection means including: an inset image projector having a plurality of video lines; and dividing means for dividing the plurality of video lines into a plurality of subraster blocks wherein each subraster block can generate an inset image; and inset image processing means, responsive to said inset image generation means, for controlling the generation of inset images by said inset image projection means, said inset image processing means including: allocation means for assigning the video signals representative of each individual inset image to an individual subraster blocks of said inset image projector; and deflection means, responsive to said allocation means, for producing positioning signals corresponding to the individual positions of each of the subraster blocks to which an inset image is assigned by said allocation means relative to the background image.
