    Abstract: A packet transmission/reception apparatus and method is provided. The packet transmission method of the present invention includes acquiring a source payload including partial source symbols from a source block, generating a source packet including the source payload and an identifier (ID) of the source payload, generating a repair packet including a repair payload corresponding to the source payload and an ID of the repair payload, generating a Forward Error Correction (FEC) packet block including the source and repair packets, and transmitting the FEC packet block. The source payload ID includes a source payload sequence number incrementing by 1 per source packet. The packet transmission/reception method of the present invention is advantageous in improving error correction capability and network resource utilization efficiency.

    Abstract: The present disclosure relates to a communication apparatus and method for supporting a forward error correction scheme in a communication system. To this end, by means of a generation mode among a plurality of generation modes (ssbg_mode #0, #1, #2), a source symbol block having a plurality of source symbols is generated by using a source packet block having a plurality of source packets, and a repair symbol block for the generated source symbol block is generated by means of a forward error correction (FEC) scheme among a plurality of FEC schemes (FEC payload ID mode 0, FEC payload ID mode 1). A first FEC scheme (FEC payload ID mode 1) is applied to generate the repair symbol block, and in response to an occurrence of a discontinuity in packet sequence numbers, a repair packet may be generated to include length repair data and a repair FEC payload identifier (ID).
