Implementation of real-time watermarking scheme for high-quality video

ABSTRACT

Digital watermarking for video helps protect the copyright of the video content. In most watermark applications, an embedding procedure should be built at low costs and the embedded watermarks should have robustness against various unintentional or malicious attacks. This paper addresses implementation issues for real-time watermark embedding scheme of High Definition(HD) resolution video on a personal computer. This paper provides some performance optimization guidelines and a simplified Human Visual System (HVS) method for fast and robust watermark embedding. Demonstration shows a real-time watermark embedding process including HD MPEG-2 video decoding, watermark embedding and displaying on an Intel architecture personal computer. Experimental results show optimized embedding performances and robustness against several malicious attacks commonly happened to videos. From the results, our implementation solution improved the embedding performance suitable for real-time watermark embedding for HD video.
