ABSTRACT:
A highly reliable display control apparatus and method suitable for use in a computer control system which is required to have high degree of reliability, such as control systems for railroad traffic or a nuclear power station. A meaningful symbol is divided into a plurality of sections and these sections are independently input to either one of the inputs of an interactive man-machine system through different systems so that these sections of the meaningful symbol are displayed in the same frame of the man-machine system, thus enabling the operator to visually detect any abnormality as to whether the displayed meaningful symbol is complete or not, whereby a high degree of reliability of the display is obtained.
