Abstract

According to the encoding characteristics of MPEG-4 video standard and the encoding principle of MPEG-4, this paper proposes a video watermarking algorithm based on MPEG-4, which is suitable for copyright protection. The basic idea of the algorithm is as follows: firstly, the watermark information is obtained from the middle and low frequency range of the DCT coefficients after the brightness component is quantified, and then the watermark information is embedded into the DCT coefficients of all the brightness components of the video sequence I frame. Finally, the simulation experiment and result analysis are given. Simulation results show that the algorithm has good invisibility.
