Patent ID: 7012982

Claim:
A method of compensating for non-constant delay times of a network transmitting MPEG-2 and MPEG-4 data packets, comprising the steps of: estimating a network system jitter associated with reference data packets carrying clock-stamped reference values, including calculating a mean jitter value associated with arrival times of a sample of data packets; adjusting said clock-stamped reference values based on said estimated network system jitter; wherein said adjusting step comprises the substeps of calculating an estimated jitter value associated with a subsequent reference data packet based on said mean jitter value; adjusting said clock-stamped reference value of said subsequent reference data packet based on said estimated jitter value associated with said subsequent reference data packet; wherein said substeps of calculating an estimated jitter value associated with a subsequent reference data packet comprises the substep of calculating a corrected theoretical arrival time of a subsequent reference data packet based on said calculated mean jitter value; wherein said adjusting step further comprises the substeps of calculating an estimated jitter value associated with a subsequent reference data packet; and adjusting said clock-stamped reference value of said subsequent reference data packet based on said estimated jitter value associated with said subsequent reference data packet.
