摘要
根据视频信号字符叠加原理 ,针对现有设计不能图文并茂且叠加字符有限的不足 ,基于MB 90 0 92芯片提出一种同时实现两路字符叠加的设计方案 对该方案进行理论分析 ,并设计电路 通过实验 。
Based on principle of on screen display, aim at the insufficiency of limited characters display on the screen and text and graphics don′t display on the same screen,a project was proposed which could realize double on screen display based on MB90092 chip.The theory of the on screen displaying and design circuit were demonstrated. This method is verified using experiments.
