Patent ID: 7554915

Claim:
A method for regulating a jitter buffer for buffering a data packet stream comprising: registering a transmission delay due to buffering for the data packets of the data packet stream; continuously deriving weighted mean delay values from registered transmission delays, wherein a shorter transmission delay is weighted higher than a longer transmission delay; and regulating a read-out speed of the jitter buffer as a function of the continuously derived weighted mean delay values so that said values are adjusted as a regulating variable to a predefined desired delay; comparing a currently registered transmission delay with a previously derived weighted mean delay value; determining a weighting of the currently registered transmission delay as a function of a result of the comparing, wherein the currently registered transmission delay is weighted with a first predefined weight value if the currently registered transmission delay is shorter than the previously derived weighted mean delay value and is weighted with a second predefined weight value if the currently registered transmission delay is longer than the previously derived weighted mean delay value, with the first weight value being larger than the second weight value, and further selecting a quotient of the first predefined weight value and the second predefined weight value to define a tradeoff between a delay introduced by the jitter buffer and a data packet loss rate.
