  • Pulldown field detector
    Patent number: 8035751
    Abstract: A system and method for detecting the presence and location of pull-down fields in a video field stream. Various aspects of the present invention may comprise method steps and circuit structure for generating an array of variance indications, each of which represents a degree of variance between two video fields in the video field stream. Various aspects may comprise comparing the array of variance indications to a pattern to detect a pull-down field in the video field stream. Various aspects may comprise comparing corresponding portions of video fields and generating a histogram of differences between the corresponding portions. Various aspects may comprise generating an indication of variance of the histogram and analyzing the indication of variance. Various aspects may comprise analyzing an array of such indications of variance and may comprise comparing the array of such indications to a pattern or plurality of patterns.
