摘要: Voice over Internet Protocol (VoIP) transmission quality predictor working in real-time provides feedback information regarding impairments, and end-user satisfaction to enhancement mechanisms along the path. Quality use this process of tuning their control parameters. The calculates rating factor R at each outputs based on voice codec, packet loss, mouth-to-ear delay. Information codec loss is determined from VoIP headers. delay an additional time stamp that inserted into RTP header by sender. Finally, play-out received packets for actual window set equal buffer output prior which gave highest R-factor value.
