Richard B Kline, Dennis Ng: Method and apparatus for adaptive smoothing delay for packet voice applications. Motorola, J Ray Wood, John Powell, Joanne N Pappas, December 5, 2000: US06157653 (71 worldwide citation)

A communication system transmits packetized voice data from a voice source to a voice destination. At the voice destination, the packets are accumulated in a buffer, sequentially played out and the time the packet waits in the buffer is monitored. The time future voice packets are played out is acco ...
