A method for deinterlacing a video signal is disclosed. Frame differences are calculated, a scene change threshold is determined based on the frame differences, a scene change is detected based on the frame differences and the scene change threshold, a stationary motion threshold is determined based on the frame differences, stationary motion is detected based on the frame differences and the stationary motion threshold, a mode of the video signal is detected based on the frame differences, and a deinterlacing algorithm is selected based on the mode of the video signal, the scene change, and the stationary motion.
