摘要
为了给用户提供良好的界面与检索的方便，有必要在监控系统中当屏显示信息（如时间、路号等）。该文介绍了两种实现ＯＳＤ的方法。结合本人的实际经验，详细介绍了采用专用集成芯片实现ＯＳＤ功能的软硬件系统设计方法。
In order to provide a friendly interface and convenience for indexing, it is necessary to display characters such as the time of day, channal numbers etc. on a TV screen in a surveillance system. The paper discusses two methods to implement OSD function, accord- ing to author's experience, and gives a detail introduction to the method using ASIC.
