Abstract
An apparatus and method for transmitting and receiving an Application Layer-Forward Error Correction (AL-FEC) packet in a multimedia communication system are provided. In the AL-FEC packet transmission method, an AL-FEC packet transmission apparatus generates AL-FEC packets, and transmits the AL-FEC packets to an AL-FEC packet reception apparatus, wherein each of the AL-FEC packets includes an AL-FEC codeword symbol and an AL-FEC header, the AL-FEC codeword symbol is one of AL-FEC codeword symbols included in an AL-FEC codeword block, and the AL-FEC header includes order information indicating an order of an AL-FEC codeword symbol into which the AL-FEC header is inserted among the AL-FEC codeword symbols included in the AL-FEC codeword block.
