The traditional error resilience technique has been widely used in video coding. Many literatures have shown that with
the technique's help, the video coding bitstream can been protected and the reconstructed image will get high
improvement. In traditional techniques, the bitstream is segmented to packets and the encoder is reset at the beginning of
each packet. The initialization will significantly reduce the coding efficiency. In this paper, we propose a new technique
to improve the error resilience using concept of disharmony degree in both spatial and temporal domain. This new
concept compares the pixels' difference in the spatial filed and temporal field, which helps retain the correctly decoder
within the bitstream improving the quality of the reconstructed image. Experimental results show that with the new
resilience technique help, the efficiency of error resilience improves the quality of reconstructed image and the detection
ratio of error blocks.
The traditional error resilience technique has been widely used in video coding. Many literatures have shown that with
the technique's help, the video coding bit stream can been protected and the reconstructed image will get high
improvement. In this paper, we review the error resilience for video coding and give the experiment of this new
technology. These techniques are based on coding simultaneously for synchronization and error protection or detection.
We apply the techniques to improve the performance of the multiplexing protocol and also to improve the robustness of
the coded video. The techniques proposed for the video also have the advantage of simple trans-coding with bit streams
complying in H.263.
