Abstract: A method and devices for dynamically embedding watermark and/or end-user access information into multimedia content. The method includes providing multimedia content transformed into blocks that each include an array of pixel blocks, and dynamically embedding portions of watermark and/or end-user access information into selected pixel blocks based on the values of the coefficients within the pixel blocks. For multimedia content encoded using discrete cosine transform (DCT) or other block-based encoding, the transform coefficients to include embedded information are chosen based on analysis of the coefficient values, rather than in a fixed or predetermined manner. Also, embedding watermark and/or end-user access information can occur across different pixel blocks within a given image to reduce the number of embedded coefficients per block, within the peripheral pixel blocks within a given image, and/or in different areas across images to reduce the duration of embedded information in any one area.

Abstract: A system, method and devices for embedding end-user access information, such as digital rights management (DRM) information and/or conditional access (CA) information, in multimedia content, such as broadcast video content, and transmitting or distributing the multimedia content, including the end-user access information, to one or more end user devices, such as multimedia content processing (set-top) devices and mobile devices. The methods, systems and devices also involve receiving and decoding the transmitted multimedia content, including extracting end-user access information from the multimedia content and using the end-user access information to allow or deny access to the multimedia content by the end user device. The end-user access information is embedded in the multimedia content in a manner that reduces or even eliminates the need to also transmit end-user access information separately or along with the associated multimedia content.
