Abstract
A method for a 3:2 pull-down film source detection. First, a source is received. Then, field differences of two fields of the same type in the source and an average field difference according to the field difference corresponding to at least one prior field in the source are calculated. The source is established as a 3:2 pull-down film source by checking whether a 3:2 pull-down signature is in the source according to the field difference and the average field difference, and a bad editing point is detected according to an interlaced frame information of the source.
