摘要：
A new robust video watermarking method is presented. Its main idea consists in adding a temporal sinusoidal sequence with its individual phase to each pixel of the video signal. The two-dimensional field of these phases corresponds to the image of the embedded watermark. Simple and fast algorithms for embedding and extracting watermarks are described. The results of experimental studies demonstrate a high quality of watermark extraction at their visual indistinguishability, robustness to some attacks, including temporal desynchronization, and a high visual quality of the protected video.
