Among bit plane coding field, coding of significance layer is an important topic. According to the advantage of quad-tree representation on codeword reduction for large zero blocks, zero block coding is a potential method in significance coding. However, traditional embedded zero block coding method exhibits repeated node visits in recursive procedure calling. In this paper, a top-to-button significance coding methodology is proposed to reduce the repeated node visiting. On the other hand, the produced coefficients are reduced at the same time. According to the experiment results, the visited node count and transmitted codeword of proposed work is smaller than original embedded zero block coding and the significance layer in Wavelet transformed coefficients of JPEG 2000. Besides, the reduction of node visiting count increases the significant bit updating efficiency. The results prove the efficiency and the effectiveness of codeword reduction of proposed work.
