<p>A method and a system for embedding a watermark in a multimedia SOC(System-On-Chip) are provided to prevent non-authorized media or a pirated version of media from being used. A cable input(101) communicates multimedia signals including audio, video data and voice. An STB(Set Top Box)(103) includes a logical algorithm, a circuitry and a command language code for receiving multimedia input signals and generating output signals to be displayed on a television(109). A storage unit(107) stores multimedia data that may have been received from the cable input and processed by a watermark SoC(105). The watermark SoC receives multimedia data from the cable input, generates a digital watermark, and inserts it into the data. The digital watermark includes a source of the multimedia data and encrypted data related to recording privileges regarding the STB.</p> |
