Embedding a digital watermark in an electronic document is proving to be a feasible solution for multimedia copyright protection and authentication purposes. In the present paper we propose a new digital video watermarking scheme based on Principal Component Analysis. We detect the video shots based on informational content, and color similarities; we extract the key frames of each shot and each keyframe is composed of three color channels, and our proposed algorithm allows us to embed a watermark in the three color channels RGB of an input video file. The preliminary results show a high robustness against most common video attacks, especially frame dropping, cropping and recalling for a good perceptual quality.
