Abstract:
This paper proposes an adaptive playout control and signal reconstruction method for speech-based audio convergence VoIP. In adaptive playout control, the buffering time is minimized by way of playing out normally or compressing each packet according to accurate network jitter estimation. Also, linear prediction-based signal reconstruction recovers lost packets and minimizes boundary discontinuities between the good packets and the reconstructed packets. The proposed receiver-based enhancing method delivers high-quality voice and music service over IP networks.
