The use of watermarks to embed user information is expected to deter the unauthorized use of video content in VOD (Video On-Demand) streaming services. This requires that watermark embedding and video encoding for each video must be finished so rapidly as to not create excessive VOD delay between the user’s video request and video download to the user. This paper describes a watermark embedding and encoding process for a fast combined watermark embedding method, and proposes a new encoding technique that minimizes video quality degradation.
