Abstract
For correction coding of a source file for transmission, the source file is divided into a plurality of groups each having a plurality of source packets. Each group is arranged into a matrix format, and braided forward error correction (FEC) packets are generated for each column, row and diagonal of a respective group by XOR'ing the source packets from the corresponding column, row and diagonal. Then, low density parity check (LDPC) FEC packets are generated for the respective group of source packets and corresponding braided FEC packets. The FEC packets generated in this manner, which are referred to as continuous FEC packets, are transmitted to a receiver component, and upon reception, an iteration of braided FEC decoding and LDPC FEC decoding is applied to the received continuous FEC packets, until all the source packets are recovered and the source file is reconstructed or until there is no more incoming packets.
