摘要:
A method and apparatus for transmitting a Forward Error Correction (FEC) packet block including a plurality of FEC packets in a multimedia system are provided. The method includes generating a plurality of first FEC packet blocks by performing a first FEC encoding on a plurality of source symbols, each of the plurality of first FEC packet blocks including at least one source packet and at least one repair packet for repair of each of the at least one source packet, generating a second FEC packet block by performing a second FEC encoding on the plurality of first FEC packet blocks, the second FEC packet block including at least one repair packet for the plurality of first FEC packet blocks, and transmitting the second FEC packet block that includes, in header information of each of the at least one source packet and the at least one repair packet.
