摘要

PPROBLEM TO BE SOLVED: To prevent sound breaks caused by a processing delay for coding in a transmitting device of a packet signal. PSOLUTION: It is estimated whether the loss of a packet occurring in packetized voice communication in an IP network is caused by the convergence of a network or the processing delay of a terminal from a packet loss rate and the value of a packet arrival jitter. When the packet loss rate is high, and the value of the packet arrival jitter is small, it is determined that the loss of the packet caused by the processing delay of the terminal has been generated, and a low-load voice coding system is selected.
