Michael J Fischer, H Lewis Wolfgang, Weimin Fang: System, method and apparatus for FEC encoding and decoding. Kencast, Fitzpatrick Cella Harper & Scinto, May 12, 2009: US07533324 (8 worldwide citation)

A system, method and apparatus are provided for encoding and decoding a source file. The source file is encoded by dividing it into a plurality of shares comprised of a plurality of packets. A bit vector is generated. For at least one share, an FEC packet is generated by XOR'ing a subset of packets ...
