Abstract
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.
