A video compression algorithm, based on hierarchical wavelet coefficients coding and overlapped motion compensation, has been proposed. Within this algorithm framework, a three-layer coding scheme of the motion vectors has been implemented to provide the embedded bit stream generation and the flexible bit budget allocation between the motion and residual image coding.
