In this work we evaluate the performance of MMSE estimation with a media-specific FEC based on VQ replicas in comparison with MAP estimation and interleaving, both operating in a DSR system over a loss-prone packet switched network. Both schemes combine a sender-driven with a receiver-based technique and, as we show, clearly outperform the standard Aurora mitigation. However, as independent techniques, interleaving and FEC codes could be jointly applied. Although this would provide better results, a direct combination of FECs and interleaving involves a sum of the delays of both operations. In this work, we introduce a double stream-based strategy that avoids this sum of delays.
