Multiple description coding (MDC) is one of the promising solutions for live video delivery over lossy networks. In this paper, we present a review of MDC techniques based on their application domain and we explain their functionality, with the objective of giving enough insight to designers to decide which MDC scheme is best suited for their specific application based on requirements such as standard compatibility, redundancy tunability, complexity, and extendibility to n-description coding. The focus is mainly on video sources but imagebased algorithms applicable to video are considered as well. We also cover the well-known and important problem of drift and solutions to avoid it  

Multiple paths are mainly used in order to achieve higher throughput and reduce the end-to-end delivery latency as well. However, the overall network performance greatly suffers from the available interference between paths, even if node disjoint multipaths are used. This problem is highlighted more when dealing with transmission of the video data where the timeliness is of primary concern. In this paper, we propose a novel Interference-Aware Multipath routing for Video Delivery (IAMVD) in the realm of wireless multimedia sensor networks. It constructs multiple paths while considering the effect of different QoS requirements of multi-priority packets, without needing any hardware support for... 

Using Peer-to-Peer (P2P) overlay networks have become a progressively popular approach for streaming live media over the Internet due to their deployment simplicity and scalability. In this paper, we propose a new hybrid push-pull live P2P video streaming protocol called PPM that combines the benefits of pull and push mechanisms for video delivery. Our main goal is to minimize the network end-to-end delay compared to the pure mesh networks. The PPM consists of two phases; Pull-based and Push-based. In the first phase, a new peer joins to the network based on a pull-based mechanism. In the second phase, a parent node based on the peers' overlay hop count in the mesh topology is selected....
