<P>PROBLEM TO BE SOLVED: To reproduce a packet of received audio data so that a user does not feel uncomfortable even by deterioration or the like in the quality of a radio communication path caused by interference waves. <P>SOLUTION: A receiving side bluetooth(R) module 15 includes a buffer for sequentially storing packets received from a bluetooth(R) module 12 of an audio server 11. After received packets of a predetermined number are stored in the buffer, while storing packets received later in the buffer, the received packets in the buffer are read out and decoded in order, so that6 real-time data are reproduced to output audio to a headphone 14. If the number of packets in the buffer becomes zero, data reproduction is stopped, packets received later are discarded and a receive radio wave strength is monitored. If the radio wave strength exceeds a fixed level for a predetermined time, the operation of storing received data packets in the buffer is started again. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
