VERFAHREN UND VORRICHTUNG ZUR KODIERUNG MIT MINDESTENS ZWEI PARALLELEN KODIERERN

摘要

A scheme for coding digital source data, implementing, in parallel, at least two elementary coding steps each taking into account all of the source data, and including a permutation step modifying a sequence of consideration of the source data between the elementary coding steps. In one example, the source data is organized in sequences of non-binary symbols, each non-binary symbol including n binary source elements, n being greater than or equal to 2. The example permutation step includes reversibly modifying contents of at least some of the non-binary symbols, delivering modified non-binary symbols, and permutating the sequence of the source or modified non-binary symbols.
