interlacing
     
        1.  A {video} display system which builds an {image}
        on the {VDU} in two phases, known as "fields", consisting of
        even and odd horizontal lines.
     
        The complete image (a "frame") is created by scanning an
        electron beam horizontally across the screen, starting at the
        top and moving down after each horizontal scan until the
        bottom of the screen is reached, at which point the scan
        starts again at the top.  On an interlaced display, even
        numbered {scan lines} are displayed in the first field and
        then odd numbered lines in the second field.
     
        For a given screen {resolution}, {refresh rate} (frames per
        second) and {phosphor} {persistence}, interlacing reduces
        flicker because the top and bottom of the screen are redrawn
        twice as often as if the scan simply proceded from top to
        bottom in a single vertical sweep.
     
        2.  {progressive coding}.
