  In this paper, we investigate an additive video watermarking method in H.264
standard in presence of the Laplacian noise. In some applications, due to the
loss of some pixels or a region of a frame, we resort to Laplacian noise rather
than Gaussian one. The embedding is performed in the transform domain; while an
optimum and a sub-optimum decoder are derived for the proposed Laplacian model.
Simulation results show that the proposed watermarking scheme has suitable
performance with enough transparency required for watermarking applications.
