Abstract
A method and apparatus for scaling interlaced video data allows the video data to be scaled to any desired size, either larger or smaller than the original image. The method considers each line of input data in each field sequentially, and determines whether the line is to be saved and whether the data lines in each successive field will also be saved, discarded, or duplicated, saving space in the output buffer for the saved and duplicated data lines to come as necessary. The method can accommodate interlaced data with N field and a scaling factor M.
