Error correction encoding method, decoding method and associated devices

摘要

An error correction encoding method is provided for encoding source digital data having the form of a frame, wherein the data can be classified into a plurality of classes. The present encoding method includes the following steps:
a first encoding step for encoding data to be encoded formed by the data of a first class, to obtain encoded data; andimplementing the following step successively for at least one other class:
mixing data of the other class and the data encoded or to be encoded from a preceding encoding step; andencoding data to be encoded formed by mixed data to obtain encoded data.;Related decoding methods, as well as encoding and decoding devices are also disclosed.

1. An error correction encoding method for encodings source digital data having the form of a frame, wherein said data can be classified into a plurality of classes, comprising the following steps:
a first encoding step for encoding data to be encoded, formed by the data of a first class, to obtain encoded data; and implementing the following steps, successively for at least one other class: mixing the data of said other class with data encoded or to be encoded from a preceding encoding step; and encoding data to be encoded formed by said mixed data, to obtain encoded data.
