For a better comprehension of this article, the first part of Section outlines a brief overview of the state of the art HEVC standard. The rest of the paper is organized as follows. In our approach, we adopt this later approach and embed the watermark message in the selected non-zero QTCs of all the frames of the video. in the quantized transform coefficients (QTCs). A better solution is to go for the frequency domain and better embed the watermark after the quantization step, i.e. But this may come at the cost of lower imperceptibility. One solution to this problem is to embed the watermark in such a way that it survives the quantization loss. With spatial domain video watermarking, the hidden data may be lost during the quantization step of the underlying video codec.

Normally, a watermark may either be embedded in the spatial domain or the frequency domain. Our strategy is to embed a watermark, during the encoding process, that can be completely extractable during the decoding process. Keeping these in view, we intend to propose an HEVC watermarking scheme that would have negligible effect on both the video quality and the final file size. Casual embedding of a watermark, thus, may escalate the final video file size or otherwise affect the quality of the video a carefully conceived embedding strategy is thus needed. ĭigital watermarking of HEVC encoded videos may be a difficult task, because the codec eliminates most of the redundancy that the watermarking process may exploit. Of special interest is the field of digital watermarking wherein the owner's/consumer's watermark is digitally embedded in the digital content, for protection against unauthorized copying as well as the ownership declaration and contents authorization. For this very reason, the integrity, verification and authentication of digital videos form an active research area today. The security of digital contents, therefore, constitutes a quintessential aspect of copyright protection in today's multimedia related industries.

One of the downside, of the ever-growing nature of Internet and multimedia technologies, is the high risk associated with the ease of manipulation, tampering and illegal copying of the digital contents, especially the multimedia. HEVC is suited for a variety of applications, such as broadcast of high definition (HD) TV signals over satellite, terrestrial transmission systems and cables, video content acquisition and editing systems, security applications, camcorders, Blue-ray discs, Internet and mobile network video and real-time conversational applications that include video conferencing, video chat, and tele-presence systems. The main goals of HEVC design include increased video resolutions and the exploitation of parallel processing architectures. High Efficiency Video Coding (HEVC) is a relatively new video compression standard, developed by the Joint Collaborative Team on Video Coding (JCT-VC), from ITU-T VCEG and ISO/IEC MPEG.
