A content-based adaptive real-time video watermarking algorithm is designed. The Arnold transform is employed to scramble the original watermark image. The algorithm embeds the watermark image into each frame of the original video adaptively based on the video content and realizes the blind extraction. The experimental results show that the proposed algorithm meets the demand of real-time and invisibility,and strong robustness is achieved under various traditional attacks,such as Gaussian noise,Speckle and frame cropping. The algorithm can be applied as one of anti-spotstamper-proofing techniques in the field of digital broadcast television.
