A method and apparatus for providing interlaced video data on a progressive display is accomplished upon receiving interlaced image data that is temporally and spatially accurate and calculating, based on a first predetermined function, calculated image data. Next, the calculated image data is compared to a threshold. When the calculated image data exceeds the threshold, the received interlaced image data is adjusted to approximate the threshold. When the calculated image data does not exceed the threshold, the received interlaced image data is adjusted to equal the calculated interlaced data. Having done this, additional information is created and subsequently combined with the adjusted interlaced image data to produce a complete field for display on the progressive display. The additional image information is of a first value when the calculated image data does not exceed the threshold and is as functional value when the calculated image data exceeds the threshold.
