Abstract
With the rapid development of multimedia technology, large amounts of digital information turn into easy storage and transmission, at the same time, copyright protection and authentication become a problem to be solved. Digital Video is composed of a series of continuous static images, because of its own characteristic, general image watermarking technology is difficult to direct extension to the video signal. In this paper, by using DCT transform and DWT transform, combined with the mean quantization algorithm, using three dimensional frequency domain transformation, introduces two kinds of transformation to the 3D video watermarking technology, utilize the quantitative test method to prove the existence of the watermark, and through the attacked experiments to verify the low complexity and well imperceptibility and robustness about the video watermarking algorithm.
