Digital Watermark is class of marker or symbol secretly embedded in a multimedia signal such as Audio, Image or Video. It is used to identify the ownership of the multimedia signal. Video watermarking is an emerging area for various applications like copy control broadcast monitoring, video authentication, copyright protection and enhanced video coding. The main objective of this paper is to present survey and comparisons of various available techniques on video watermarking based on copyright protection and identification. Comparative study of various technologies gives the significant information about the PSNR, payload, quality factor and also the various attacks used in video watermarking techniques. The best techniques in various scenarios are discussed in this paper which will help the research scholars in field of video watermarking.

“…PROPOSED SCHEME In this paper, we propose an effective video watermarking embedding method based on the DCT-CS domain. In MPEG coding, the video sequence is first divided into groups of pictures or frames (GOP) considered I-frame, B-frame, and P-frame [4]. According to the video sequence characteristics, the B-frame and P-frame are dependent on the I-frame.…”

“…Thereby, it is a great challenge to design a robust information hiding system where the hiding parameters scale properly with reduced bitrates and one has to trade-off data embedding capacity to obtain robustness at higher compression rates. For some video compression formats, such as MPEG-2 and MPEG-4, the number of variable parameters are many more (i.e., variation in bit-rate, Group of Pictures size, and so on) [4], [5]. Therefore, design of the video information hiding needs to be synthetically considered, in which video watermarking scheme is robust to variation in these parameters and achieves high compression ratios from both spatial and temporal domains [6], [7].…”

Abstract-Video watermark is an important tool using for protecting digital content in information security field. In video watermark achievement, the embedding method is an important technology. For protection fingerprint images by the video watermark, the paper proposes a novel 3-D bedding scheme which can hide digital fingerprint images in DCT-CS domain. The extensive experiments have shown that the proposed scheme can effectively obtain the better trade-off between robustness and statistical transparency.Index Terms-Digital watermark, discrete cosine transform, compressed sensing, robustness.
