The copyright protection of digital videos is becoming more important with the development of multimedia technology.A novel adaptive video watermarking scheme integrated of several techniques is proposed in this paper in order to obtain one practical watermarking.The scheme is robust against manifold attacks and the watermark can be retrieved blindly.First

the watermark was scrambled by Arnold scramble and Turbo coded to obtain the improved security.Secondly

the key frames were selected based on the video characteristics such as frequency sensitivity

chroma sensitivity

movement sensitivity

texture sensitivity and luminance sensitivity which were summarized in this paper.Then the key frames were segmented to three dimension blocks and the watermark was embedded into the middle-low frequency domain of the three dimension wavelet decomposed coefficients of the blocks.In addition

a new method was adopted which can extract the invariable information of rotated and zoomed videos by Zernike movement.The invariable information can be used to conquer rotating and zooming attacks.Finally

the watermark was retrieved blindly.The robustness was obtained with attacks and tests to the typical videos.Experimental results demonstrate that the scheme is accommodated to videos with various content characteristics and can conquer the present attacks.It has certain practical values.
