Digitalvideoisone of the popular multimedia data exchanged in the internet. Due to their perfectly replicable nature many illegal copies of the original video can be made. Watermarking is relatively a new technology that has been proposed to solve the problem of illegal manipulation and distribution of digital video. It is the process of embedding copyright information in video bit streams. Our scheme embeds different parts of a single watermark into different scenes of a video under the Discrete wavelet domain. To increase robustness of the scheme, the watermark process is carried out in the video. Our video watermarking algorithm is robust against the attacks of frame dropping, averaging and statistical analysis, which were not solved effectively in the past. In video data embedding scheme the embedded secret data is randomly segmented and reconstructed without knowing the original host video. Secret data isembedded in individual video frames using the frequency domains of DWT. Finally the PSNR reading is compared for the Original Video & Watermarked Video.
