A wavelet based algorithm for scalable video compression is described, with the main focus put on memory bandwidth reduction and efficient VLSI implementation. To achieve this goal, the proposed algorithm adopts a modified 2-D subband decomposition scheme in conjunction with a parallelized block-based EZW (embedded zerotree wavelet) coder. Experimental results are also shown in comparison with motion JPEG and MPEG2 so as to demonstrate the viability of the proposed algorithm
