Abstract: Adaptive playout algorithm is an important component of the Internet multiparty real-time communication system. The authors bring forward a new adaptive playout algorithm in the multiparty real-time communication fields based on the consideration of the impact of the packet loss dependency using E model tool. The aim of the algorithm is to give the best voice feeling to users as well as the best voice quality. The experiment results prove the validity of the algorithm. The algorithm can reduce the packet loss probability and delay significantly, and reduce the consecutive packet loss simultaneously.
