Hardware realization of DC embedding video watermarking technique based on FPGA

Abstract

In this paper, a video watermark technique is proposed. The proposed technique depends on inserting invisible watermark in Low Frequency DCT domain using pseudo random number (PN) sequence generator for the video frames instead of high or mid band frequency components. This technique has been realized using Matlab and VHDL. The system has been implemented on Xilinx chip XC5VLX330T. The result of implementation shows that maximum frequency 13.61 MHZ. The experimental and implementation results has been demonstrated and discussed.
