This paper studies the temporal error propagation of small errors in a single frame for H.264 video. Such small errors can arise due to imperfect recovery from loss, e.g., through error concealment. The key contribution of this paper include demonstrating empirically that small errors tend to amplify over time, and is primarily caused by rounding errors in motion compensation and selective application of deblocking filter based on thresholding. Some methods of reducing error amplification is also presented. |
