IMPROVED RESILIENCE FOR VIDEO OVER PACKET LOSS NETWORKS WITH MDC AND OPTIMIZED PACKETIZATION

We investigate the problem of robust video transmission over packet loss networks. A resilient video coding framework is important to ensure quality video over these networks. We propose a combination of multiple description coding and an optimized packetization method to constitute the error resilient codec. Multiple description coding technique utilizes path-diversity (multiple paths between sender and receiver) in networks by sending the descriptions along different paths. An optimized strategy for packetizing the descriptions is also proposed which guarantees that each packet is self-contained and efficient. Experimental results show that the proposed method achieves improved video quality over lossy networks.
