针对视频监控对多通道同时监控的应用需求，开发了多画面监视控制器，它可同时监视和控制4路模拟视频输入、并输出2路模拟视频, 还能将ATM机上的点钞数据同步叠加到视频画面.描述了该监视控制器的功能、硬件组成，并重点介绍了视频输入、视频控制和视频输出的软件实现方法.

According to the application demand for monitoring multi-channel synchronously, the multi-channel monitoring controller was designed. It can monitor 4 analog composite video inputs, and supports 2 analog video outputs. The data outputting by Currency counting Machine can also be displayed on video. The functions, hardware structure of multi-channel monitoring controller is described. The implementation methods of software for video inputs, video control and video outputs are mainly introduced.
