Slepian and Wolf proposed and analyzed a ground-breaking paradigm of source coding for a source network in which a finite alphabet source X is to be encoded and transmitted to the decoder, and another finite alphabet source Y correlated with X is available only to the decoder as a helper, or in other words, the side information. In Slepian and Wolf's paradigm, which is now commonly referred to as Slepian-Wolf (SW) coding, information flow is one-way from the encoder to the decoder, and no interaction is allowed between them.In this paper, we consider a paradigm of source coding called interactive encoding and decoding (IED). The paper answers the question: what can be gained by IED over SW coding?
