Recently, new challenges are imposed to secure video broadcasting and sharing, and to guarantee confidentiality, integrity, copyright and traceability. In addition, due to the social media development, several new problems have emerged in users' privacy and security policy as identity theft, copyright infringement and unauthorized content sharing. The watermarking is a crucial way to assure safety objectives as it allows embedding an imperceptible mark in the digital video data. In this paper, we integrate two robust watermark schemes in a high efficiency codec HEVC, which can be easily implemented in the codec since they require only little extra computation. Experimental results demonstrate that our proposed scheme (named XY method) does not affect the video quality, nor escalate bitrate. Our digital watermarking system presents a trade-off between capacity, fidelity, bitrate and robustness parameters.
