With a new lattice structure which uses fewer parameters, M channel filter banks are designed. Aimed to the orthogonal and bi orthogonal system, different parameterizations are proposed to structurally impose the regularization. Based on these filter banks, the video coding scheme is developed. Using explicit quantization and priority search zerotree algorithm, the zerotrees can be found quickly and efficiently. Great improvement over the H.263 is convinced.
