Parameter Reference
3.19.1.15 Jitter-Buffer Minimum Delay (DMG2000 Only)
Description: Specifies the minimum jitter-buffer delay. The smaller the delay, the smaller the
jitter-buffer. It is recommended that this value be at least the duration of one RTP packet interval. If
the minimum, maximum, and initial jitter-buffer delays are set to the same value, the jitter-buffer
will operate in the non-adaptive mode.
Allowed Values: 0 to 200 milliseconds
Default Value = 20 milliseconds
INI File Parameter Name = dspJbDelayMinMs
3.19.1.16 Jitter-Buffer Maximum Delay (DMG2000 Only)
Description: Specifies the maximum jitter-buffer delay. A larger delay provides protection against
larger network jitter, but increases audio delay. It is recommended that this value be set to at least
four times the duration of one RTP packet interval. If the minimum, maximum, and initial jitter-
buffer delays are set to the same value, the jitter-buffer will operate in the non-adaptive mode.
Allowed Values: 0 to 200 milliseconds
Default Value = 200 milliseconds
INI File Parameter Name = dspJbDelayMaxMs
3.19.1.17 Jitter-Buffer Initial Delay (DMG2000 Only)
Description: Specifies the starting jitter-buffer delay. It is recommended that this value be set to at
least two times the duration of one RTP packet interval. If the minimum, maximum, and initial
jitter-buffer delays are set to the same value, the jitter-buffer will operate in the non-adaptive mode.
Allowed Values: 0 to 200 milliseconds
Default Value = 20 milliseconds
INI File Parameter Name = dspJbDelayInitMs
3.19.1.18 Jitter-Buffer Adaptation Period (DMG2000 Only)
Description: Controls the speed at which the jitter-buffer adapts downward when network
conditions allow. The larger the value, the slower the jitter-buffer adapts downward when jitter
decreases.
Allowed Values: 1000 to 65535 milliseconds
Default Value = 10000 milliseconds
INI File Parameter Name = dspJbAdaptationPeriodMs
