Source coding with a side information ‘vending machine’at the decoder Conference Paper uri icon


  • The role and potential benefit of Side Information (SI) in lossless and lossy data compression is a central theme in information theory. In ways that are well understood for various source coding systems, S.1.can be a valuable resource, resulting in significant performance boosts relative to the case where it is absent. In the problems studied thus far, the lack or availability ofthe SI, and its quality, are a given. But what if the system can take actions that affect the availability, quality, or nature of the SI? For example, consider a source coding system …
