Abstract :
We consider N-layer scalable source coding of a finite memoryless source X~px. We propose an iterative algorithm which is a generalization of the Blahut-Arimoto algorithm for rate-distortion computation. The algorithm is initialized with arbitrary nonzero reproduction probabilities, and monotonically approaches the optimal reproduction distribution
