In this paper, we will propose a fast video watermarking technology to hide copyright information by a least modification of the motion vectors in compressed video bitstream. During the process of watermark embedding and detecting, we must estimate the motion vector first. In order to reduce the computational burden, we present a novel fast estimation algorithm based on the block sum pyramid. Simulation results indicate that our method is effective and practical.
