Studies on multiple description coding based on lower-tree wavelet

Multiple description coding (MDC) algorithms based on the lower-tree wavelet (LTW) are presented and studied, suitable for real-time applications of video delivery. One is based on different quantizers to the wavelet coefficients according to the quardtrees. And the other is based on the structure unanimity of the two descriptions generated from wavelet coefficients according to the bit plane. Experimental results for the transmission of image demonstrate the efficiency of the proposed method.
