The Research And Implementation Of Synchronization Technology For The Capture Platform Of Video Information

In this paper, the platform of interception of computer video leaking information is discussed, the character of video horizontal and vertical synchronous signals are analyzed in time and frequency domain, and the design and implementation of synchronous signal generator is completed.At first, the meaning, application and development of the interception and reduction of computer video leaking information is discussed.The second, the structure of the platform for interception and reduction of computer video leaking information is introduced.And the key technologies are discussed,including the interception of computer video leaking information,the analysis of video information and the generation of horizontal and vertical synchronous signals also included.The third, the design and implementation of the hardware and software of synchronous signal generator are completed based on DDS technology through two means,one is based on FPGA and the other is based on SCM and DDS chip.At last,a experiment is designed and tested,using the generator designed above.
