    Proposes a lossless video coding scheme based on a reversible wavelet packet, and subband domain motion estimation. In lossless transforms, integer input signals are transformed into integer transform coefficients and losslessly reconstructed. Our method permits both intra- and inter-frame coding to proceed in the wavelet transform domain. The subband divisions by wavelet packet are varied effectively. And the motions between two successive frames are described as the translation of subband blocks. Each frame is referred to the next frame. The prediction differences are encoded by a zero tree coding scheme to provide some desirable features including exact bit-rate control, quality and resolution scalability, progressive transmission, good compression performance and possibility of lossless coding. This paper offers the availability of our strategy in lossless video coding.
