1. A video display system comprising:

  • a cathode-ray tube having a light-emitting screen which is capable of emitting light representing two or more colors of the visible spectrum;

    a plurality of electron guns disposed in the cathode ray tube for emitting a corresponding plurality of electron beams which impinge upon a corresponding plurality of portions of the light-emitting screen so as to cause the plurality of portions to emit light;

    means for horizontally deflecting the plurality of electron beams across the entire width of the light-emitting screen for repetitively tracing a corresponding plurality of generally straight lines across the entire width of the light-emitting screen;

    means for vertically deflecting the plurality of electron beams at approximately the time that the means for horizontally deflecting completes the tracing of the plurality of lines across the entire width of the light-emitting screen so as to substantially eliminate tilting of the plurality of lines on the light-emitting screen;

    input means for receiving a plurality of parallel video signals each representing a different one of two or more colors of the visible spectrum; and

    reformatting means, connected to the input means, for storing the video signals.
