数字视频系统接口应用

随着技术发展,数字视频接口逐步替代模拟视频接口,成为视频产生、传输、显示、存储的主要方式.列举了常用的模拟和数字接口,阐述了视频系统前端与后端数字视频接口的特点及应用情况.通过分析各个端口的性能和实际军事需要,得出Camera Link接口是现在军用光电产品中的主要发展和应用方向.并且从接口的发展趋势来看,未来的数字接口是向摄取速度更高、传输带宽更宽、分辨率更高的方向发展.

The application of interfaces in digital video system

With the development of technology, the digital video interface instead of the analog interface has become a main way in all kinds of video application. The common analog and digital interfaces are listed in this paper, and their characteristics and application in the front-end and back-end of video system are introduced. Based on the analysis of the performance of each interface and the needs of actual military, Camera Link is shown as the main development and application direction of military electro-optical device. In the view of the development trend, the future digital interface will be faster in acquisition, wider in transmission and higher in resolution.
