    Abstract: The aim of the present invention is to enforce the watermarking on a content received by a client device, in particular to uncompressed video content. The present invention concerns a method to watermark an uncompressed content received at a client device in a compressed form and encrypted by at least one content key (CW), said content key (CW) as well as watermark instruction forming CAS data, said CAS Data being encrypted by a transmission key and comprising at least one signature to authenticate the CAS Data, said client device comprising A Conditional Access Module (CAS) in charge of the CAS Data, a Descrambler (DSC) having an input to receive the encrypted compressed content and an output to produce an compressed content, a decoder to convert the compressed content into uncompressed content, a Watermark inserter (201) connected to the output of the Decoder, a Secure Activation module (202) connected with the Watermark inserter (201), a Secure Element (SE 200) connected with the Watermark inserter (201) and the Secure Activation module (202), said method comprising the following steps : - receiving the CAS Data, - decrypting by the Conditional Access Module (CAS) the CAS Data with the transmission key, - verifying the signature of the CAS Data, and if the signature is valid, - transferring the content key (CW) to the descrambler (103) and the watermark instruction to the Secure Activation module (202), - transferring the watermark instruction and the unique identifier to the Watermark inserter (201), - enabling or disabling watermarking by the Watermark inserter (201), the uncompressed content received from the Decoder by watermarking data initialized by the unique identifier.

    Abstract: Methods, devices, systems and computer program products utilized watermarks that are embedded in a content to facilitate content access, and to enhance a user's experience by allowing the user to explore additional options for obtaining the desired content and related items of interest, in one method, an indication for an access to a content is received that includes one or more copy management watermarks and one or more enhanced payload watermarks. At least one copy management watermark and at least one enhanced payload watermark are extracted from the content. Upon a determination, based on the at least one copy management watermark, that access rights to the content is restricted, the enhanced payload watermark is used to present one or more alternative options.
