  • Adaptive jitter buffering
    Patent number: 6452950
    Abstract: In a packet communication system, the delay time needed in a jitter buffer is determined, enabling a smooth data feed to an application without excessive delays, by methods and apparatus that vary the size of the jitter buffer based on an estimated variation of packet transmission delay derived from the times of arrival of stored packets. A variance buffer stores variances of the times of arrival of stored packets, and the estimated variation of packet transmission delay is derived from the stored variances. The size of the jitter buffer can be changed preferentially during periods of discontinuous packet transmission.
