In this paper, we propose an efficient watermarking scheme for H.264/SVC, where the watermarking is performed by using a block-based approach. The embedding process of watermark in the proposed scheme is performed in the encoder of H.264/SVC. The blocks for watermarking embedding are selected by considering both the length of the watermark signal and the size of the input video frame. The water...

In scalable image/video coding, high resolution content is encoded to the highest visual quality and the bit-streams are adapted to cater various communication channels, display devices and usage requirements. These content adaptations, which include quality, resolution and frame rate scaling may also affect the content protection data, such as, watermarks and are considered as a potential wate...

Nowadays, digital data is easily tampered. Therefore the need of digital data protection has been increased with the advancement in the technology. Watermarking is a technique used to protect the digital data. Embedding watermark in a video is what called as video watermarking. Digital video watermarking is a technique by using which user can get the copyright of its product which prevents the ...

Watermarking is known to be a very difficult task. Robustness, Distortion, Payload, Security, Complexity are many constraints to deal with. When applied to a video stream, the difficulty seems to be growing in comparison to image watermarking. Many classical non malicious manipulations of a compressed stream may suppress the embedded information. For example, a simple re-compression of a DVD mo...

In this work we apply a direct sequence spread spectrum model to the watermarking of digital video First, video signal is modeled as a sequence of bit planes arranged along the time axis. Watermarking of this sequence is a two layer operation. A controlling m-sequence first establishes a pseudorandom order in the bitplane stream for later watermarking. Watermarks, defined as m-frames, supplant ...

In today’s life need of security is require in digital media due to the extensive use of digital media applications, multimedia security and copyright protection has gained tremendous importance. Digital watermarking is technology used for various applications. In field of digital media like copyright protection, Authentication etc. A lot of techniques are available for protecting the copyright...

Due to the extensive use of digital media applications, multimedia security and copyright protection has gained tremendous importance. Digital Watermarking is a technology used for the copyright protection of digital applications. In this paper, a comprehensive approach for watermarking digital video is introduced. We propose a hybrid digital video watermarking scheme based on Discrete Cosine T...
