Recent advances in forward error correction and scalable video coding enable new approaches for robust, distributed streaming in Mobile Ad Hoc Networks (MANETs). This paper presents an approach for distribution of real time video by uncoordinated peer-to-peer relay or source nodes in an overlay network on top of a MANET. The approach proposed here allows for distributed, rate-distortion optimiz...

A method to construct nonasymmetric distributed source coding (DSC) scheme using polar codes which can achieve any point on the dominant face of the Slepian–Wolf (SW) rate region for sources with uniform marginals is considered. In addition to nonasymmetric case, we also discuss and show explicitly how asymmetric and single source compression is done using successive cancellation (SC) polar dec...

The study of distributed coding system design for correlated sources has largely focused on the basic problem, with the implicit assumption that practically motivated extensions involving scalable or predictive coding may be obtained in a straightforward manner. In this paper, we show that naively extended approaches yield poor ratedistortion performance. In fact, inherent conflicts arise betwe...

The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sumrate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of the RD...

Group-theoretic construction and analysis of generalized coset codes for symmetric/asymmetric distributed source coding. Abstract | In this paper we consider the problem of distributed source coding with symmetric and asym-metric rates of transmission with a constructive and practical approach, referred to as DIstributed Source Coding Using Syndromes (DISCUS). We employ generalized coset codes ...

In recent years, distributed video coding emerged as an alternative to conventional video coding. While conventional video coding is based on motion estimation and compensation, distributed video coding makes use of the principles of distributed source coding developed by Wyner and Ziv. In this paper, we investigate the rate distortion tradeoffs in distributed video coding. We present a model f...
