摘要： PROBLEM TO BE SOLVED: To obtain sufficient burst loss resistance without increasing delay even in a low data rate. SOLUTION: This data transmitter packetizes transmission data (encoded data) by a packetizing part 112, performs redundancy coding by an FEC (Forward Error Correction) coding part 113 and subsequently transmits the resultant data to a network 130 from an RTP (Realtime Transport Protocol) transmitting part.
