Abstract

PURPOSE:To decrease the required buffer length and delay time and to keep constant the overall transmission delay amount, by setting suitably the value of additional delay amount every section of tone. CONSTITUTION:An analog audio signal inputted from an audio input device 1 is coded at a coder 2. The 1st buffer 3 is a buffer for one audio packet, and if the discrimination by an audio detector 4 is within tone section, the ''PAD'' 6 assembles the audio packet by using the data in the 1st buffer 3, and the audio packet received through the network interface 9 from the exchanging network 8 transmitted to the packet exchange network 8 through the network interface 7 is divided into the header part and the information part at the ''PAD'' 10, and the information part is transmitted to the 2nd buffer for delay adjustment. Further, the counter 13 counts the normal nonaudio packet keeping time. Thus, based on the information of the counters 5, 13, the additional delay amount at the 2nd buffer 11 is suitably adjusted at the control section 12.
