Picture display arrangement
First Claim
1. An arrangement for the display of individually selectable map pictures as background information combined with overlay information comprising selectable predefined and/or operator generated symbols, characterized in that said arrangement comprise:
- a video disc player with a video disc carrying said map pictures and having means for repeated playback of a selected map picture;
a computer having a memory storing map access information of each map picture and storing symbol generative data of said predefined symbols, and an operator input means for the selection of a map picture and a defined symbol;
a picture generator for transforming into a video signal the symbol generative data which is supplied from said memory;
a video mixer having video signal inputs which are connected to outputs of the video disc player and the picture generator and having mixing means for overlaying RGB-components of symbol video signals with priority onto RGB-components of map video signals such that the symbol picture non-transparently covers the map picture; and
means for displaying the so combined video signal.

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.
