Static and Adaptive Jitter Buffer
9.5.5 Minimum Delay in Adaptive Jitter Buffers
In adaptive operating mode, the jitter buffer tries to keep the average delay as low as possible.
In a situation where no jitter occurs, the average delay falls to a minimum. This minimum can
be set on the HG board. The average delay that is adjusted on the basis of the current mea-
sured delay therefore fluctuates between two limits: the minimum delay set and the maximum
delay set. The following illustration shows this:
The minimum and maximum delay limits are even maintained in the event of packet loss.
