The paper proposes that Embedded Zreotree Wavelet algorithm and the architecture of the modified EZW algorithm will have the property of regularity, modularity ,and scalablity, and also posses the function , which can allow a detected watermark to be embedded. The methods to realize the algorithm and the function of watermark are to analyze the theory of algorithm and the order of output and input data and then to use queue and stack, the unit of memory, and the control of circuit. The modified EZW architecture needs a half less memory units than the original one, and functions nearly as effective as the original architecture. Besides, this paper points out that the whole architecture of the transform CODEC system can be applied properly to HDTV, MPEG-4 system, or QoS network.
