In order to embed a watermark in the original video, a preprocessing operation is required in the content encoding process. A watermarked value (0 and 1) is inserted in the original uncompressed video frame to generate a watermarked frame and output as two sets of encoded video.
The inserted watermark value is encrypted using a secret key unique to each content service provider, and can not be extracted from the outside arbitrarily.
