Allowed Values: 0 to 200 milliseconds
Default Value = 200 milliseconds
INI File Parameter Name = dspJbDelayMaxMs
3.10.2.18 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
3.10.2.19 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
3.10.2.20 Jitter-Buffer Deletion Threshold (DMG2000 Only)
Description: When the jitter-buffer grows past this value, frames exceeding the threshold are
deleted immediately.
Allowed Values: 0 to 500 milliseconds
Default Value = 500 milliseconds
INI File Parameter Name = dspJbDeletionThresholdMs
3.10.2.21 Jitter-Buffer Frame Deletion Mode (DMG2000 Only)
Description: Determines how frames are deleted when the jitter-buffer adapts downward.
Allowed Values:
Soft = More emphasis on audio quality, but maximum delay may be exceeded.
•
• Hard = Hard cap on the maximum delay, which may negatively impact audio quality.
