....It compensates for the delay variation (jitter) using a playout delay adjustment algorithm [7, 16, 14, 3, 2] Simple algorithms use a xed playout delay, either static or determined at the start of a session. More advanced VoIP applications compute a di erent playout delay for each talk spurt [4] adaptively according to the current network condition. The quality of multimedia applications is primarily determined by packet loss and delay. First, if a packet is lost, the media quality degrades unless there is a recovery mechanism such as Forward Error Correction (FEC) 15] 18] or ....

....low bit rate redundancy FEC as mentioned in [9] A low bit rate redundancy FEC would serve as a type of loss concealment in Figure 1. 4.1 Simulation Setup of Spurt Gap Pattern, FEC, and Playout Control VoIP applications often use silence suppressions to transmit only talk spurts. Study of Brady [4] and Daigle [6] have found the spurt gap distributions to be approximately exponential. We use an exponential distribution (1.5 sec average) plus a bottom threshold (240 ms) to describe the length distribution of both talk spurts and silence gaps. The randomly generated spurts and gaps are then ....

....meaning is clear. Many techniques have been developed for controlling playout delay [13] 36] 28] 7] 6] etc. Simple ones use a xed playout delay, either static or determined at the start of a session. More advanced techniques exploit the existence of talk spurts (speech) and pauses (silence) [8] in human speech. The length distribution of talk spurts and pauses depends on silence detector settings and the speaker, but Brady [8] reported that the average length of spurts and pauses is on the order of 1 second. Since human perception is less sensitive to the length of silence, the ....

This way the ....
