Abstract
The invention relates to a process for an improved video display. Depending on the amount of motion contained in the video data, either the bob or the weave method of de-interlacing is used. If video data is in the progressive format, then no de-interlacing is used. After initially determining which method of de-interlacing to use, the invention continues to monitor the amount of motion in the data and changes the de-interlacing method if the amount of motion in the video data changes.
