Title: Method and apparatus for de-interlacing video fields to progressive scan video frames

Abstract: A method and apparatus are provided for converting interlaced video fields of arbitrary size to progressive scan format video frames of arbitrary size. The method and apparatus of the invention provide consistent conversion quality even while output video dimensions are scaled in real-time. According to a first aspect of the invention the space between output lines is calculated with respect to the input fields. According to a second aspect, the output line spacing information is used to calculate the final line positions in a progressive scan output frame.
