A NEW VoIP ADAPTIVE PLAYOUT ALGORITHM
A novel playout algorithm for VoIP applications is presented. The playout times of voice packets are calculated using adaptive estimation of network delays. In contrast to previous solutions, the weighting factor that controls the estimation process is dynamically adjusted according to the observed delay variations. This results in higher-quality estimates of network delays. With this algorithm...
متن کاملAn Adaptive Jitter Buffer Playout Algorithm for Enhanced VoIP Performance
The QoS standard of a VoIP session degrades if its stringent time requirements are not met. Low end-to-end delay of the voice packets and low packet loss must be maintained. Jitter between voice packets must also be within tolerable limits. Jitter hampers voice quality and makes the VoIP call uncomfortable to the user. Very often, buffers are used to store the received packets for a short time ...

متن کاملVoIP Playout Buffer Adjustment using Adaptive Estimation of Network Delays
The poor quality of Voice over IP can be improved by adaptive playout buffering at the receiver. This technique dynamically adapts the playout deadline to network conditions, thus minimizing both late packet loss and buffering time. A standard playout buffer strategy uses an estimate (Exponentially Weighted Moving Average) of the mean and variance of network delay to set the playout deadline. T...
متن کاملAn application of neural networks to adaptive playout delay in VoIP
IP networks are not designed for real-time voice data. The statistical nature of data traffic and the dynamic routing techniques employed in IP networks results in a varying network delay (jitter) experienced by IP packets. As a result voice packets generated at successive and periodic intervals at the source will typically be buffered at the receiver prior to playback in order to smooth out th...
