A pixel‐domain Wyner‐Ziv residual video coding scheme is presented. In this scheme, based on the statistical distribution characteristics of the residual signal, an adaptive binary‐to‐Gray code converting process is designed so that virtual channel noises can be lowered over bit‐planes. Through simulations, it is shown that the best case performs better than the DISCOVER scheme as well as the worst case.
