Abstract :
We present a novel fine granular scalability (FGS)-based statistical multiplexing scheme for video broadcasting. In the light of our statistical study on intra- and inter-layer correlation, we develop a simple but efficient statistical multiplexing algorithm based on the proposed fairness criterion and smoothness constraint. Simulation results show effectiveness of the proposed statistical multiplexer in terms of high multiplexing efficiency, high bandwidth utilization, fairness and smoothness.
