Abstract:
A method of distributing digital video sequences in the form of a stream including sequences of data containing digital images, including a modification stage of an original stream by modifying at least a part of the sequences, the modification producing a modified stream of the same nominal format as the original stream, transmitting the modified stream, and a reconstruction stage implemented with a decoder, wherein the reconstruction is adaptive and progressive in function of information coming from a digital profile of the recipient.
