Abstract
A receiver device having a processor, memories, descrambler and decoders modules configured to produce a sequence of elementary media content packets. The receiver device further comprises a marker unit configured to mark data in the sequence of elementary media content packets according to a pattern defined by an internal parameter associated to the receiving device. The marker unit is configured to determine, in the sequence of elementary media content packets at least one segment of a predetermined length and starting at a predetermined position in the sequence, to divide the segment into a predetermined number of contiguous windows including data of all or part of at least one elementary media content packet. Each window in the segment defined in the sequence of elementary media content packets is indexed by an index defining a position of a window in the segment. The marker unit codes the internal parameter by applying a mathematical transformation function, obtaining a resulting bits string, calculates position indices of a predetermined number of windows on the basis of all or a portion of the resulting bits string, said predetermined number of windows being lower than the number of windows in the segment, and modifies data in the windows designated by the calculated position indices. The windows including modified data and the windows including original data from within the segment of elementary media content packets a unique pattern representing the internal parameter associated to the receiving device.
