<p>Packets received through a network interface 104 is stored into a receiving buffer 108. A reproduction controller 106 checks the current state of receiving buffer 108 and performs a reproduction process mentioned below. The data in receiving buffer 108 is transferred to a decoder 109 in accordance with instruction from reproduction controller 106 and decoded as voice sound, D/A converted by a D/A converter 110 and then output as voice sound from a speaker 102. The clock for D/A conversion is supplied from a reproduction clock CLK 107. This configuration is free from overflow and underflow of the receiving buffer due to difference in clocks between the transmitting and receiving ends, and prevents the occurrence of packet jitter so as to avoid voice sound breaks. <IMAGE></p> |
