An improved motion picture coding scheme is described which provides the benefits of both sub-band coding and motion compensation thereby providing greater degrees of compression than would be obtained using either of these techniques separately. The system generates high and low frequency frames from...http://www.google.fr/patents/US5272530?utm_source=gb-gplus-shareBrevet US5272530 - Method and apparatus for coding motion pictures utilizing motion compensation
