摘　　要：提出了一种新的嵌入式视频监控解决方案,其通过硬件实现对模拟视频信号的视频解码、图像处理,完成后直接在LCD显示屏或CRT显示器上显示。XScale嵌入式处理器负责网络通信、无线通信和人机交互。本系统功能全面,并有很好的扩展性,比如可扩展实现网络远程监控或者监控视频的数字化存储。A new embedded video monitoring solution is proposed. In this approach, the tasks of decoding the analog video signal and processing the images are executed by the specific hardware, and then the processed signal is directly displayed on the LCD or CRT screen. XScale embedded processor is responsible for wire or wireless network communication and man - machine interaction. The solution is comprehensive in the functionality and of great ability of extension, for example, the function of digital storage for data in remote monitoring system or video surveillance system can be accomplished by the extension parts.
