| 摘 要： | 设计了一种基DSP和CPLD的视频叠加系统，利用视频解编码芯片、DSP和CPLD对视频数据进行采集、处理，构成可以脱离计算机的视频叠加系统，同时它还可以根据需要叠加任意字符和图像。系统主要特点是并非基于通常所采用的专用的视频叠加芯片，而是通过DSP和CPLD来实现视频叠加的功能。

Design and Implementation of Video Overlap System Based on DSP/CPLD |
| |
| Abstract: | A video overlap system is designed based on DSP and CPLD, which grabs and composes data by using video decoder, video encoder, DSP and CPLD to compose overlap system without assistant computer. It can overlap any character or graph. A distinguishing feature of the system is that it is not based on special video overlap chip that is common in this field, but uses DSP and CPLD to finish overlap functions. |
