    Abstract: The present invention provides a means and an apparatus for watermarking a digital signal. A particular content which is to be made available by a content provider to potential content users is prepared by encoding the content into a plurality of encoded streams, each encoded stream being encoded according to a different bit-rate. Each encoded stream comprises a plurality of chunks and each chunk is retrievable by a requestor of content. Upon request of said content by a user, the plurality of chunks making up the content are selected from the plurality of the different encoded streams and a subset from that plurality of chunks is watermarked using a unique identifying parameter associated with the requestor.

    Abstract: The present invention relates to a process for the distribution of video streams to a plurality of addressees, comprising a marking stage consisting in adding at least one visual element to this video stream, which marking stage is applied to an original video stream common to all the addressees and which is personalized for each addressee by the addition of a visual elements specific to the addressee that allows a rapid visual identification of this addressee, characterized in that this added visual element replaces part of the original video stream that is stored in the complementary information on the multimedia server. Another characteristic of the invention is that the reconstitution and the display of the original stream are carried out on the client equipment from the modified stream and from complementary information sent by the server after authentication of the client and as a function of his rights for being read and viewed without the display of the visual elements.
