Abstract (en)
[origin: WO0059166A1] There is disclosed a voice data transmission system in which voice data is transmitted via a communication line in the form of data packets, which can reduce problems of interruption of the message transmittal and also of the communication delay. In this system, the data packets from the transmitting side are sent out onto a communication line at predetermined constant time intervals. At the receiving side, the data is retrieved at constant time intervals identical to the aforementioned predetermined constant intervals at which the data packets are sent out from the transmitting side. The data packet size is preferably smaller than that of a conventional system, and the time interval at which the data packet is sent out is preferably smaller corresponding to the data packet size. The preferable interval for sending out the data packets is not larger than approximately 60 ms, more preferably approximately 20 ms.
