摘要

A method of encoding data for transmission from a source to a destination over a communications channel (145) is provided. The method operates on an ordered set of input symbols (205) and includes generating a plurality of redundant symbols from the input symbols (205). The method also includes generating a plurality of output symbols from a combined set of symbols including the input symbols and the redundant symbols, wherein the number of possible output symbols is much larger than the number of symbols in the combined set of symbols, wherein at least one output symbol is generated from more than one symbol in the combined set of symbols and from less than all of the symbols in the combined set of symbols, and such that the ordered set of input symbols (205) can be regenerated to a desired degree of accuracy from any predetermined number of the output symbols.
