PROBLEM TO BE SOLVED: To enhance transmission efficiency of music data. SOLUTION: In the case that a transmitter 1 transmits music data read from an audio reproducing device 4 that cannot access an optional address of music data to a receiver 2 via a general public network 3, a data storage section 7 stores the music data in a random access enabled way in a prescribed unit, and when an error detection section 13 of the receiver 2 detects that an error takes place in part of the music data that are transmitted, the transmitter 1 reads only the part having the error among the music data stored in the data storage section 7 and retransmits the read data. |
