摘要
随着数字视频压缩技术的不断发展,基于数字技术的多媒体监控系统开始逐步替代传统的图像监控系统。基于多媒体监控系统采用数字技术对信号进行采样和压缩,所以它可以实现网络传输,而不用采用传统的视频电缆或者光纤传输,大大节省了成本,同时更容易实现对图像的存储、处理和控制。论文采用嵌入式操作系统,在ARM7平台上实现多媒体的监控。
Along with the digital video compressed technology unceasingly developing, the system is substituting gradually digital technology multimedia supervision for traditional image supervision. The multimedia supervisory system that uses digital technology carry on the sampling and compression to the signal, therefore it can realize network transmission, however, it that does not need to use traditional video electric cable or fiber optic transmission, has saved the cost greatly, at the same time is easier to realize the image memory, processing and the control. This paper uses embedded system that realizes the multimedia monitoring in the ARM7 platform.
