ABSTRACT
Distributed Video Coding (DVC) is a coding paradigm that
gives the decoder the task to exploit the source statistics to
achieve efficient compression. Many approaches to the
DVC problem have recently appeared in the literature,
including the PRISM codec. Instead of encoding the
deterministic quantized prediction error residual, PRISM
partitions the quantization lattice into cosets and sends the
