VIDEO ENCODING SYSTEM AND WATERMARKING MODULE FOR WATERMARKING A VIDEO SIGNAL AND METHOD FOR USE THEREWITH
A watermarking module can be used in a video encoding system that processes a video signal. A watermark data module generates original watermark data based on either non-watermark data that is based on the video signal and or that includes a codeword associated with a scrambling of content included in the video signal. A watermark generation module generates a watermarked video signal in accordance with the original watermark data.
