摘　　要：视频字符发生器是一种在视频电子信号中叠加字符信息的系统,即把字符或时间信号加入到视频信号中,使之在屏幕的特定位置上,以特定的模式显示出来。如:显示日期、时间、图片等有关数据。本系统的视频输入信号接VCD/DVD,视频输出信号接电视机,可以通过按键实现内同步或外同步功能,在视频上显示指定的字符和图片,通过添加少量的外接电路来实现温度采集以及实时显示的功能。Video character generator is one kind of information system overlapping character or time into video signal which can be displayed in a specific pattern at a specific location on the screen, such as the date, time, pictures and other relevant data. The video input signal is connected with the VCD / DVD, the video output signal is connected with the television. Internal synchronization or external synchronization function can be achieved only by press- ing the key, so that specific characters and pictures can be displayed on the screen. Besides, temperature acquisition and real time display Iunctioncan he achieved only by adding a small amount of external circuit.
