FPGA based implementation of real-time watermarking for high definition video

In this paper, we propose a real-time video watermarking chip and system which is hardware based watermark embedding system of HD (high definition) video with STRATIX FPGA device from ALTERA. There was little visual artifact due to watermarking in subjective quality evaluation between the original video and the watermarked one. Embedded watermark was all extracted after a robustness test called format conversion video attacks such as HDMI (high definition multimedia interface) to HD-SDI (high definition serialized digital interface) conversion. Our implemented watermarking hardware system can be useful in movie production and broadcasting companies that requires real-time based copyright protection system.
