A technique that provides smoother, less jagged edges for interlaced video playback. Interlaced video consists of alternating odd and even numbered scan lines, which are then mapped to an equivalent pixel-by-pixel display on a CRT or Flat Panel Display. Without correction, jagged lines appear in a video image either as doubled scan lines or lines that are improperly interpolated. With vector adaptive deinterlacing, the difference in pixel values is considered across multiple lines and alternating frames (using 3:2 pulldown on the interlaced video source), and then intelligently re-interpreted to produce smoother edges in interlaced video images.
