System for highly reliable file delivery of using continuous fec encoding/decoding

A system for at least encoding a source file to be transmitted to a receiver, comprising:

• a packetizer configured to:
• divide the source file into a plurality of groups of source packets, each group comprised of a plurality of source packets;
• and
• for each respective group of source packets, arrange the source packets into a matrix format;
• and
• an encoder configured to:
• for each respective group of source packets in the matrix format, generate braided forward error correction (FEC) packets;
• select a polynomial and a pseudorandom generator, wherein coefficients of the polynomial are non-negative and the sum of all coefficients of the polynomial is one;
• generate, using a randomly selected number selected according to the coefficients of the polynomial, a low density parity-check forward error correction (LDPC FEC) packet for the respective group of source packets and the corresponding braided FEC packets generated for the respective group;
• generate a continuous FEC packet by adding corresponding header information to the LDPC FEC packet, wherein the header information comprises information regarding the components of the LDPC FEC packet from at least one of the source packets of the respective group and the corresponding braided FEC packets generated for the respective group;
• and
• repeat the steps of generating the LDPC FEC packet and the continuous FEC packet for at least one additional group of source packets in the matrix format.

A non-transitory, computer-readable medium storing a program having program codes which, when executed by a computer, perform a method for at least encoding a source file to be transmitted to a receiver, the method comprising the steps of:

• dividing the source file into a plurality of groups of source packets, each group comprised of a plurality of source packets;
• for each respective group of source packets, arranging the source packets into a matrix format;
• for each respective group of source packets in the matrix format, generating braided forward error correction (FEC) packets;
• selecting a polynomial and a pseudorandom generator, wherein coefficients of the polynomial are non-negative and the sum of all coefficients of the polynomial is one;
• generating, using a randomly selected number selected according to the coefficients of the polynomial, a low density parity-check forward error correction (LDPC FEC) packet for the respective group of source packets and the corresponding braided FEC packets generated for the respective group;
• generating a continuous FEC packet by adding corresponding header information to the LDPC FEC packet, wherein the header information comprises information regarding the components of the LDPC FEC packet from at least one of the source packets of the respective group and the braided FEC packets for the respective group;
• and
• repeating the steps of generating the LDPC FEC packet and the continuous FEC packet for at least one additional group of source packets in the matrix format.
