“…Inserting the watermark in the compressed domain is an alternating for low-complexity video watermarking techniques. The video compression standard, H.264 with better feature at very low bit rates and high compression ratio [3] is employed in an expansive series of relevance. Seeing that an upshot, scheming a robust watermarking method, which is apt for this standard, is extremely attractive.…”

In this paper, a pristine method of tough digital video watermarking algorithm in H.264 compressed domain is articulated. Most of the video watermarking techniques interleave the watermark in Iframes but in this paper a fabulous method of blind low complexity video watermarking in P-frames for H.264 video is proposed. Our algorithm decides which 4x4 block within the macro-block of P-frame will be set in based on the covert key. The proposed method restricts embedding by selecting only the nonzero quantized ACresiduals of P-frames, thus escalating the watermark robustness. Simulation outcome illustrate that there is decrease in bit rate and at the same time it is robust to quite a few diverse attacks. Keywords-Digital video watermarking, AC Coefficient, P-frame, bit rate, H.264.
