Abstract

An arrangement for the display of individually selectable map background pictures combined with an overlay of selectable predefined or operator generated symbols. The arrangement comprises a video disc player with a video disc carrying the map pictures and a computer in which symbol generative data of the predefined symbols are stored. A picture generator transforms the symbol generated data into a video signal and a video mixer combines the video signals of a map picture and symbol generative data such that the symbol picture non-transparently covers the map picture. The combined signal is displayed on a color monitor. The video disc allows for rapid access to a large number of maps and the generation of the overlay information requires only a limited computer capacity. The arrangement is specifically useful for rapid and flexible indications of military operations.
