Digital video watermarking algorithm robust against video container format changes

A digital watermark embedding algorithm robust against any changes of a video container format with the use of a three-dimensional (3D) discrete cosine transform is proposed. For embedding the three-dimensional (3D) method based on Koch and Zhao's two-dimensional (2D) method is applied. The image of a digital watermark and its digital hologram as embedded information are used. Embedding is carried out in a YUV color scheme. Computer-simulation experiments are made. The proposed method proved to be robust against attacks of video container format changes.
