| Abstract: | 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. |
