FORWARD ERROR-CORRECTING (FEC) CODING AND STREAMING

摘要

PROBLEM TO BE SOLVED: To provide a method of generating encoded data comprising source symbols which are data to be encoded and repair symbols which can be used for reproducing information about missing source symbols in a data encoder.

SOLUTION: The method comprises: obtaining a generator matrix which represents encoding of the repair symbols from the source symbols; reading at least some of the source symbols; including the at least some of the source symbols as encoded symbols in an encoded set in an order in the encoded set corresponding to an order of the source symbols in the ordered plurality of source symbols; reordering the source symbols according to a set of one or more reordering rules to form a reordered set of source symbols; applying the generator matrix to the reordered set of the source symbols to form a set of repair symbols; and outputting the encoded set as the encoded data and the set of repair symbols.
