In this paper, a pseudo-bitrate mechanism to simulate the layer op- timization step in rate allocation is proposed. The simulation forces bit readjustments in the compressed bitstreams so that all significant bitstreams will be transferred to the first q − 1 output layers leaving more space in the last qth layer for hiding data. Experimental results showed that pseudo-bitrates can be used to manipulate the amounts of data-to-hide in the compressed bitstreams.
