Patent ID: 6922731

Claim:
A gateway for interconnecting two networks, comprising: a receiver for receiving from a first network a plurality of data units in at least one form; a controller for temporarily storing in a buffer the data units received by the receiver and for outputting the data units stored in the buffer to a destination terminal served by a second network while reducing jitter of the data units output by the controller; and a transmitter for sending data units corresponding to the data units corresponding to the data units output by the controller to the destination terminal through the second network, wherein the controlled is adapted to reduce the jitter of the data units to within a permissible delay jitter limit which is determined on the basis of reducing jitter capability of the destination terminal, and wherein the controller includes: an output time detector for detecting a first time moment at which a first data unit in each form is output from the controller; and a delay calculator for calculating the delay time of each data unit based an the first time moment, wherein the controller determines the precedence, so as to transmit the data unit of which the determined delay time is longer than that of the other data unit, with priority over the other data unit.
