When do we use channel prefixing in information theory problems and why ? for example Csiszar and Korner used it to characterize the rate-equivocation region for general, not necessarily degraded, wiretap channels. C=max_{p(x)}(I(V;Y)-I(V;Z)) when we have this markov chain : V-X-Y where the channel is Broadcast with the input X and output Y(legitimate) and Z (eavesdropper)
