Digital video is very sensitive to bit errors which are injected especially in wireless transmission. Because the effects of errors in encoded digital video differ from analog video, traditional signal distortion measures, like peak signal-to-noise ratio (PSNR), do not correlate perfectly with the subjective quality of the video. In this paper, a novel method which does not need reference information about the original video is presented. It is assumed that MPEG-4 with video packets is used, and that error concealment is done by replacing the erroneous areas from the previous frame. The results obtained with the method are in line with PSNR.
