A system or a method that produces a similarity (or a differential) value that is used to indicate whether two video fields are either similar or not. The system or method assigns an index value to the current field based on the similarity (or a differential) value. The system or method determines how to process further the current field based on whether the assigned index value comprises an even or an odd number. The system or method processes the current field with the immediately preceding field if the current field's assigned index is an even number, and with the immediately following field if the current field's assigned index is an odd number. The system or method generates at least one output video frame that is at least twice the resolution of the current field being processed.
