摘　　要：随着计算机技术与视频图形图像技术的不断发展,机载航空电子系统中的综合显示处理技术也得以长足发展,需要处理和显示的视频信息量越来越大,格式越来越多。文章研究能够在机载综合显示系统中实现多种视频格式的选择和叠加功能。结合机载综合显示系统对视频技术的需求,研究了高性能多格式视频叠加模块的硬件设计和软件叠加算法。在机载综合显示系统液晶显示器上实现了叠加后的视频图像,满足了机载显示系统的要求。With the development of computer technique and video graphic technique, the integrated display techniques are also well developed in the avionics system. The video information and formats need to be displayed and processed are getting more and more. This paper studies the selection and overplays function of multi video formats that will be realized in the airborne integrated display system. And combined with the requirements of airborne integrated display system on video technique, the hardware design and software overplay algorithm of high-performance and multi formats video overplay module are studied. The overplayed video images are displayed on the LCD of the airborne integrated display system, and the requirements for avionic display system are met.
