Strong Successive Refinability and Rate-Distortion-Complexity Tradeoff

We investigate the second order asymptotics (source dispersion) of the successive refinement problem. Similar to the classical definition of a successively refinable source, we say that a source is strongly successively refinable if successive refinement coding can achieve the second order optimum rate (including the dispersion terms) at both decoders. We establish a sufficient condition for stron...
