Abstract
We introduce the DCT pyramid as a layered video coding technique. For efficiency of coding, we propose an optimum bit allocation method for the layers of the DCT pyramid. The proposed method is based on minimization of the overall reconstructed error with the Lagrangian multiplier and distribution of the bit budget among the layers. Experimental results on the improvement due to optimum bit allocation are also presented.
