Abstract
Abstract A method and apparatus for coding video includes constructing motion-compensated extended base layer reference frames from base layer frames and at least portions of base layer residual image frames. The motion-compensated extended base layer reference frames are used for bi-directionally or uni-directionally predicting FGS motion-compensated residual image or temporal frames.
