Abstract Information technology equipment has found its wide applications in modern large-scale electronic systems such as new type of computers. Their security has increasingly become an important issue in computer application areas. With the enhancement in the resolution and the video bandwidth of monitors, the addition equipment ceaseless update, the radiation of new type of interfaces and associated video cables increases constantly. In addition, the high cost of project suffers from serious electromagnetic shielding issues. By taking the red signal in computer video systems as the mainline and based on the analysis of the digital signals and principles of video interception, I n view of the features of signal transmission of HDMI and LVDS, the time-domain and frequency-domain models of both systems are established. In addition, the transmission path of red signal of both systems is determined and the method of associated test is proposed. Through the experience the correctness and effectiveness of the proposed theory and methods are verified. The method based on FPGA information processing of anti-compromising emanations of digital video information system is researched in this paper. According to the spread spectrum communication and chaotic sequences , the anti- intercept arithmetic based on time-domain is proposed. In addition, the algorithm based on chaotic sequences and wavelet is researched, Simulation research and performance evaluation show that the proposed algorithm is both feasible and effective.
