Abstract This paper researched an improved digital video watermarking
algorithm based on relationship. The algorithm combines the video
processing and video coding compression principle which adopts
improved Arnold algorithm as well as the technology of the block and
carries out a series of replacement process in the \textit{DCT}
coefficients of the video frame \textit{YCbCr} spatial luminance
$Y$ components. Meanwhile, we segment information watermark image,
aiming at the information watermark and mark watermark to be double
embedded to improve the watermark embedding capacity and computing
speed of the algorithm. Simulation results show that this algorithm
can keep good invisibility of watermark. It has good robustness to
video compression processing and special video attacks which can
realize the blind extraction and random watermark detection.
