Abstract:
1. A receiver for smoothing jitter experienced by data packets in transmission from a transmitter to said receiver, comprising: a counter for determining delays experienced by data packets in transmission from said transmitter to said receiver, a delay estimator adapted to estimate data indicative of an adaptive packet delay histogram, having a mean, wherein said data indicative of the packet delay histogram is a function of the delays experienced by said data packets in transmission from said transmitter to said receiver and the number of data packets received at the receiver; a playout delay evaluator in data communication with the delay estimator and adapted to receive data from said delay estimator, wherein the playout delay evaluator calculates a playout time, and wherein the calculation of said playout time utilizes said mean and a first variance derived from a portion of said data indicative of the packet delay histogram; and a playout buffer monitor adapted to receive said playout time from said playout delay evaluator, buffer the data packets for a delay amount determined by the playout delay evaluator and then output the delayed data packets.
