A robust adaptive multiple video watermarking algorithm is proposed for some of the current lack of multi-watermarking algorithm.The algorithm combines the scrambling technology,color space conversion and visual system characteristics adaptively embedded the multiple binary image watermarking in the DCT middle-low-frequency coefficients of the original video frame's brightness component.The algorithm can achieve the multi-watermarking embedded in the video carrier and the blind extraction.The experimental results show that the algorithm can ensure the quality of the video,and the algorithm is robust against general attacks.
