• With the advent of digital video and digital broadcasting, copyright protection of video data has been one of the most important issues.We present in this paper a novel method of digital watermark for video data based on the discrete wavelet transform.In this method, we embed the watermark in the lowest frequency components of each frame in the uncoded video by using a controlled quantization process.The watermark can be extracted directly from the decoded video without access to the original video.Experimental results show that the proposed method gives the watermarked image of better quality and is robust against MPEG coding and re-encoding.Furthermore, we discuss multiple watermarking with regard to the generational copy control for video contents.
