A coded moving-picture signal is decoded by a resolution-converting motion compensation process and a resolution-converting inverse discrete cosine transform, both of which decrease the resolution of the picture, thereby reducing the amount of reference picture data that has to be stored and accessed....http://www.google.es/patents/US6584154?utm_source=gb-gplus-sharePatente US6584154 - Moving-picture coding and decoding method and apparatus with reduced computational cost
