Rate-distortion optimized packet scheduling and routing for media streaming with path diversity

The diversity for media streaming in a rate-distortion optimization framework was considered. A sender-driven transmission scenario was also investigated. Diversity was achieved by using multiple transmission paths over the network. The proposed framework enables the sender to decide at every instant which packets, if any, to transmit and over which transmission paths in order to meet a rate constraint while minimizing the end-to-end distortion. Experimental results demonstrate the benefit of exploiting packet diversity in rate-distortion optimized sender-driven streaming of packetized media.
