Abstract
A method for detecting progressive material in a video sequence is disclosed. The method generally includes the steps of (A) calculating a plurality of block statistics for each of a plurality of blocks in a current field of the video sequence, (B) calculating a plurality of field statistics by summing the block statistics over all of the blocks in the current field, (C) calculating a noise level for the current field based on a subset of the block statistics from each of the blocks and (D) generating a mode flag for the current field based on both (i) the field statistics and (ii) the noise level, wherein the mode flag identifies if the current field is part of a 2:2 pull-down pattern.
