摘要
介绍了一种网络监控设备的设计方法.采用ADI公司ADSP-BF533嵌入式处理器,通过并行外围接口(Parallel Peripheral Interface,PPI)控制视频信号数据流的高速传输,编程对信号进行MPEG-4压缩.实现了数字视频图像的采集、压缩及网络传输.实际应用证明,该系统数据传输可靠,图像清晰.
A design method of supervisory equipment based on network was introduced. Using ADSP- BF533 embedded CPU produced by ADI Co. , the high speed transmission of video-signal data flow via Parallel Peripheral Interface (PPI) was controlled and the signals were compressed in MPEG-4 mode. Digital video capture, data compression and network transmission were realized. Data transmission is reliable and image is clear in practical applications.
