Abstract:
1. A delay jitter reducing device, comprising: a receiving unit sequentially receiving chronological data segments through a network; a time detecting unit for obtaining a reception time of each data segment received by said receiving unit; transmission time estimating means for estimating transmission time of each data segment received by said receiving unit; a delay time estimating unit for estimating a delay time required for transmitting each data segment based on said reception time and said transmission time of each data segment; a minimum delay time estimating unit for estimating a minimum delay time in transmitting a data segment through the network from the estimated values of delay time of a plurality of data segments obtained from said delay time estimating unit; relative delay time computing means for obtaining a relative delay time by subtracting said minimum delay time from the estimated value of delay time of a data segment estimated by said delay time estimating unit; and delay means for obtaining an amount of holding time corresponding to each data segment by subtracting the relative delay time of each data segment from a maximum delay time to be reduced, and outputting each data segment after delaying each data segment for the amount of holding time corresponding to each data segment.
