Efficient scalable motion coding for wide-range scalable video compression

For a scalable video coder to cover a wide range of bit-rates, e.g. from mobile video streaming applications to TV broadcasting, it is essential that motion information presents some form of scalability. In this paper we propose a new accuracy-scalable motion codec in a wavelet-based spatio-SNR-temporal-scalable framework. It allows to decode a reduced amount of motion information at sub-resolutions, taking advantage that motion compensation requires less and less accuracy at lower spatial resolutions. This new motion codec proves its efficiency in our full-scalable framework, by improving significantly video quality at sub-resolutions without inducing any noticeable penalty at high bit-rates.
