Abstract :
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.
