Abstract: With the development and popularization of the Internet, the protection the copyright of
digital media contents, especially the digital videos contents became a crucial research direction. In
order to improve the robustness of the watermark, this research proposed an energy difference method
to embed the digital watermark information into the video frames through DCT transformation of the
video frame information. The videos embedding the watermark can be released as MP4, AVI, and
WMV formats, and the analyzation of bit error rate and peak signal to noise ratio of the digital videos
showed that this algorithm can resist digital image processing, including strong compression and
various filtering. This study provides a new method for the copyright protection of digital videos.
