To enable robust multiview video streaming over current wireless broadcast infrastructures, this paper proposes a joint source and channel coding optimization framework for video streaming based upon multiview video coding technique. It utilizes random linear coding (RLC) with ladder-shaped global coding coefficient matrix (GCM) for unequal erasure protection. An accurate expression of the decoding probability for RLC with ladder-shaped GCM is derived. A fast two-layer local search algorithm is developed to solve the source and channel coding rate allocation problem, where the source and channel rate of each layer can be adjusted independently for the overall video quality. Simulation results demonstrate significant video quality improvement to existing rate allocation schemes.
