  • Abstract
    This paper proposes a simple multiple description video coding approach based on zero padding theory. It is completely based on pre- and post-processing, which require no modifications to the source codec. Redundancy is added by padding zeros in the DCT domain, which results in interpolation of the original frame and increases correlations between pixels. Methods based on 1D and 2D DCT are presented. We also investigate two sub-sampling methods, which are interleaved and quincunx, to generate multiple descriptions. Results are presented for two zero padding approaches using H.264, which shows that the 1D approach performs much better than 2D padding techniques, at a much lower computational complexity. For 1D zero padding, results show that interleaved sub-sampling is better than quincunx.
