Abstract :
A method for creating two-layer video from a single-layer MPEG bit stream is presented. The main feature of this method is a continuous B frame stream enabling B frame cell loss to occur in preference to anchor frame cells. It is demonstrated that this method can protect anchor frame cells better than rate-averaging of each group of M frames when sources are strongly aligned
