摘要：

In this paper, an efficient error resilience scheme aiming to give priority protection to certain area such as region of interest (ROI) In frame based on Wyner-Ziv(WZ) coding for wavelet based video transmission is proposed. By utilizing additional WZ coding, all the corresponding wavelet coefficients related to ROI will be specially protected during transmission on error prone channel and eventually ROI area can be better reconstructed. Comparing to FEC algorithm fully applied to all wavelet coefficients to realize protection, the proposed scheme has distinct advantages in saving bandwidth and robust transmission..
