Patent ID: 7369179

Claim:
A method of detecting a telecine pattern embedded within a first sequence of video frames, the method comprising: receiving at least a portion of the frames from the first sequence of video frames; measuring a plurality of differences between frames and their adjacent frames in the sequence and storing the measure differences; arranging the measured differences into a plurality of data groups for analysis wherein each data group of the plurality comprises an “in-group” and one or more “out-groups,” wherein each in-group comprises two or more selected measured differences between adjacent frames that are spaced 5 frame intervals apart, wherein each corresponding out-group comprises other measured differences between adjacent frames; performing a statistical analysis of the in-groups and the out-groups of the plurality of data groups to determine which data group has the in-group that corresponds to duplicate frames of the telecine pattern; and generating a second sequence of video frames from the first sequence by removing one or more duplicate frames from the first sequence.
