Large capacity data processing is the focus of research and development in the field of military communications at present. Video data is a typical representative of large capacity data processing, and it is becoming more and more widely used. In this paper, The system using the OMAP3530 chip can not only improve the data processing capacity, but also meet the real-time transmission of video data. We can have a real-time and directly understanding of the current situation changes in the battlefield by the video data, and enhance the ability of coordination combat of various parties concerned and the whole fighting efficiency.
