Rate-distortion with a limited-rate helper to the encoder and decoder Academic Article uri icon


  • Abstract Consider the rate-distortion problem, in which a helper sends a common limited- rate message both to the encoder and decoder based on side information at its disposal. We characterize the region of achievable rates and distortions for this problem. We derive these regions explicitly for binary doubly symmetric sources with Hamming distortion, and for Gaussian sources with square error distortion. We also consider the more general problem where additional side information is available at the decoder and provide a single letter …
