Abstract :
In this paper, we introduce a new methodology for SNR video scalability which is based on the partitioning of the DCT coefficients. The partitioning is done in a way that is optimal in the rate-distortion sense. The optimization is performed using Lagrangian relaxation and dynamic programming (DP). Experimental results are presented and conclusions are drawn
