Huffman codes used in JPEG coding are replaced with reversible variable-length codes (RVLCs) with larger free distance. The extra redundancy is used in a joint source-channel codec based on the state transition probabilities of the RVLC. After accounting for the penalty due to increased average codeword length, the RVLC scheme achieves a 4 dB gain over an equivalent turbo coded JPEG transmission system.
