Yong-Jae Jeong, Kwang-Seok Moon, Jong‐Nam Kim · 2008
In this paper, we propose an applicable technique in the real time applications using FPGA chip implementation technique which can be implemented by Haar wavelet based real time video watermarking for robust watermarking for copyright protection of video contents. Proposed method does algorithm design which can reduce computation complexity for hardware implantation and then implement hardware. In implementation result, we can confirm correct watermark inserting by FPGA simulation tool and cannot recognize concealed watermark in video sequence which insert watermark in original video sequence using implemented hardware watermark embedder system. Our implemented watermark embedding chipcan be useful in movie production and broadcasting companies that requires real-time based copyright protection system.
