Abstract
A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) determining a protection condition by performing a static check on the picture in a region around a location interlaced with a first field of the picture, (B) calculating an interpolated sample at the location by temporal averaging the first field with a second field in response to the protection condition indicating significant vertical activity and (C) calculating the interpolated sample at the location by spatial filtering the first field in response to the protection condition indicating insignificant vertical activity.
