Abstract:
In the last few years new research has demonstrated that distributed source coding (DSC) techniques can be applied to multiple media compression scenarios and have demonstrated that these techniques have potential benefits in terms of encoding complexity and error resilience. DSC originates in the information theoretical work of Slepian, Wolf, Wyner and Ziv in the 1970s. In this talk we first provide a short introduction to the key intuitions behind DSC. We then discuss several applications of these techniques: video compression with flexible playback, scalable video coding and compression of hyperspectral imagery. These applications help us illustrate the potential of these technques as well as the very significant remaining research challenges they pose.
