Abstract : A study was made of various techniques for a binary-to-video converter suitable for accepting binary information from a computer (or similar type of input) and producing a display on a TV raster. Information to be shown on the display included alpha-numerics, symbols, map data, and similar processed-data readout in the form used for command and control displays. It is concluded that a data converter system capable of storing a digital representation of entire TV rasters would provide the most satisfactory solution. Where a number of different display pictures are to be assembled for simultaneous viewing by different persons at different local areas, a common system with a magnetic drum which provides multiple outputs is recommended. Time sharing most of the common system elements will provide a substantial savings in overall cost. A feasibility model utilizing the data converter concept was built and delivered to Rome Air Development Center, Griffiss Air Force Base, Rome, New York. For economic reasons, a small size core memory was used in place of a full size magnetic drum for video data storage. (Author)
