Abstract [en]

This report gives an overview of how to achieve robust transport of real-time audio streams over lossy Internet connections. Due to congestion and jitter, packet delay and loss are incurred on these audio streams, resulting in distortion. The losses can be repaired using receiver-only, sender-initiated or receiver-initiated techniques. Depending on the actual network condition, an optimal technique can be selected using adaptive behavior in the applications. Studies have shown that losses up to 20% can be effectively repaired using fairly simple techniques. The report also gives initial results from subjectively evaluating audio quality and presents an research prototype called mAudio that has been used to experiment with many of the loss recovery techniques mentioned in this report.
