    Abstract: A method by which a signal transmission device transmits packets in a communication system is provided. The method includes the operations of, generating a source symbol block including one or more source symbols having the same length by using a source packet block including one or more source packets; generating a restoration symbol block generated using one or more restoration symbols by performing a forward error correction (FEC) coding operation on the source symbol block; generating an FEC source packet including the source packets and an FEC payload identifier (ID) and transmitting the FEC source packet to a lower protocol; generating an FEC restoration packet including one or more of the restoration symbols and the FEC payload ID and transmitting the FEC restoration packet to the lower protocol; and transmitting FEC configuration information including information on the source symbol block generation operation to a receiver.

    Abstract: A method and apparatus for decoding received packets in a broadcasting and communication system is provided. The method includes reconstructing a source block by arranging source packets received from a sender on a two-dimensional array having a width of a given symbol size, and determining at least one Erased Subdivided Encoding Symbol Index (E-SESI) corresponding to at least one source packet which is not successfully received in the reconstructed source block, determining a symbol unit for Forward Error Correction (FEC) decoding based on the at least one E-SESI, and performing FEC decoding on the reconstructed source block depending on the determined symbol unit.
