The invention relates to monitoring a content diffusion in a telecommunications network (R). Said media content contains data which is specific for a given content acquisition rights and is recorded in a form of a digital watermark (WM). During the transmission through an access network (RA), the content is analysed in order to detect the presence of a digital watermark. The specific acquisition data is, afterwards, extracted from the watermark and transmitted, together with data specific for a current transmission, to a central device (300) monitoring the telecommunications network (R) in order to determine the legality of the current transmission. |
