摘要

本文研究了H.264中传输误差的影响。由于运动预测，传输错误会传播到后续帧中，导致视频质量下降。仿真结果表明，H.264具有非衰落特性。我们提出了一种引入衰落特性的方法，可以消除几帧后的误差传播。基于与MPEG-4和每帧剩余能量的比较，我们对我们的结果进行了详细的分析。

Exponential Decay of Transmission Distortion in H.264

In this paper we investigate the impact of transmission errors in H.264. Transmission errors propagate into subsequent frames due to motion prediction and result in degraded video quality. Our simulations show that H.264 exhibits non-fading behaviour. We propose a method that introduces a fading characteristic and can eliminate the error propagation after a few frames. We provide a detailed analysis of our results based on a comparison with MPEG-4 and the residual energy per frame.
