G. Feideropoulou, J. E. Fowler, B. Pesquet-Popescu, and J.-C. Belfiore, “Joint Source-Channel Coding of Scalable Video with Partially Coded Index Assignment Using Reed-Muller Codes,” in Proceedings of the International Conference on Image Processing, Genoa, Italy, September 2005, vol. 3, pp. 888-891.

• Abstract:
  Joint source-channel coding of scalable video using motion-compensated temporal filtering is considered. The proposed coding scheme consists of a structured vector quantizer based on lattice constellations and a linear index assignment which minimizes simultaneously the channel and source distortions. Both uncoded linear index assignment as well as partially coded linear index assignment via Reed-Muller codes are considered. The proposed system is compared to an unstructured quantizer with minimax index assignment. Simulation results indicate that, for a Gaussian channel, the structured-codebook scheme is very robust, maintaining near-noiseless performance even when the channel is very noisy. Additionally, the proposed structured-quantizer scheme outperforms its unstructured counterpart when channel noise levels are high.
