METHOD FOR INSERTING WATERCARE ASSISTANCE DATA IN A CODED DATA BIT FLOW REPRESENTING A DIGITAL CONTENT AND BIT FLOW CONTAINING THE WATERCARE ASSISTANCE DATA

摘要

method for entering watermark assistance data into a bit stream and a bit stream containing watermark assistance data. the invention relates to a method for introducing assistance data with watermark (wsm) in a bit stream (f) of encoded data, comprising the insertion step (12), in the bit stream, of identification data identifying the coded data to be replaced and, for each coded data to be replaced, at least one replacement data. the method further comprises an insertion step (14) in the bit stream of a format data defining a way of replacing the encoded data to be replaced by the replacement data.
