Digital watermarking has become very important for protecting the authenticity of multimedia objects as they become easier to copy, exchange, and modify due to the large diffusion of powerful personal computers. The video has been utilized in a variety of applications such as video editing, Internet video distribution, wireless video communications etc. Some of these applications are likely to get great benefit from video watermarking technology. Main objective of this research is to design robust perceptual video watermarking targeted at achieving better performance and reliability. Due to its robust nature, Discrete Cosine Transform (DCT) watermarking was chosen in this work to accomplish video copyright protection. The watermark is inserted in the video stream during compression, resulting in an optimized compression/watermarking algorithm and system.
