    A new video watermarking scheme resistant to synchronization attacks is presented. We propose to embed only a few copies of the watermark along the temporal axis into frames, which are located at the borders of each two different scenes of the video. As a result, each change of the video scenes is transformed into synchronization pulse, which is used for watermark embedding and extraction. For resisting to rotation and scaling attacks we proposed to present a watermark in a form of the ring area. Such representation gives an opportunity to convert the ring area rotation to its shift, which is compensated by using a phase-frequency spectrum corresponding to the original angular position of the watermark. Experimental results show the robustness of the proposed scheme.
