We describe a scheme for rate-distortion with distributed encoding in which the sources to be compressed contain a common component. We show that this scheme is optimal in some situations and that it strictly improves upon existing schemes, which do not make full use of common components. This resolves in the negative an open question regarding whether independent quantization followed by independent...
We propose a new coding scheme for the symmetric K-channel multiple description problem based on the quantization splitting technique, which was previously successfully applied to the Gaussian CEO problem. Unlike a coding scheme we discovered earlier, the scheme proposed here can provide performance better than the one by Pradhan, Puri and Ramchandran in a component-wise manner. Though the method...
