A novel interleaving algorithm for robust video transmission

In this paper, we propose a novel interleaving scheme for robust transmission of video sequences. By optimally grouping macroblocks (MB) into slices, robustness can be achieved with negligible reduction in coding efficiency. We group MB into slices considering the maximal minimal distance of these MB. Since every lost MB has as many as possible spatial neighbors that belong to other correctly received slices, an error-concealment mechanism has a lot of information it can employ for efficient concealment. Experimental results demonstrate the robustness of the proposed scheme.
