The invention relates to a method of distributing digital audio sequences in the form of streams comprising sequences of data containing digital audio blocks. The inventive method comprises a step involving the modification of the original stream, whereby at least one part of the aforementioned data sequences is modified, said modification producing a modified stream with the same nominal format as the original stream. The method also comprises a modified stream distribution step and a reconstruction step using a decoder. The invention is characterised in that the reconstruction of the original stream is adaptive and progressive according to the information originating from a digital profile of the recipient. In one particular embodiment, the modification step produces a modified main stream and complementary information which enables the original stream to be reconstructed by a decoder, the method comprising a modified stream distribution step and, in addition, a step involving the transmission of a subpart of the above-mentioned complementary modification information to the destination equipment, whereby the subpart is determined according to the information originating from a digital profile of the recipient. The invention also relates to a system for implementing said method. |
