The video watermarking scheme based on H.264 coding standard

In this paper, a better video watermarking scheme based on H.264 coding standard is presented. Embed the watermark into high frequency coefficients of luminance component “Y” from the “I” frame of the video data in the DCT domain. Due to avoid participating the quantification process which may damage the watermark and it makes the scheme have a better capacity of adapting the lossy compression coding. Meanwhile, the invisibility and robustness can both be better performance. The simulation results show that the scheme avoids the influence of quantification effectively. Many kinds of influences on embedded watermark can be controlled, thus, the security is improved and it can prove the effectiveness of the scheme. The results show that this scheme has a good performance in compression attack.
