Abstract
A method for inverse telecine. The method generally includes the steps of (A) checking if a current field of a plurality of fields in a video sequence repeats in the video sequence according to a pattern-based approach where the current field fits a telecine pattern, (B) checking if the current field repeats according to a first pattern-less approach where the current field complies with at least one of a plurality of rules and (C) generating a signal for an encoder in (i) an asserted state if the current field repeats and (ii) a deasserted state if the current field does not repeat.
