嵌入式数字视频监控系统的实现

Implementation of Embedded Digital Video Monitor and Control System

该文提出了ARM7为内核的数字视频监控系统的设计与实现方法,其特点是在该系统中实现MPEG 2图像压缩标准及相应的控制功能.文中简述了系统的组成、结构与功能,并重点研究了如何在低速的ARM7上实现高速以太网传输与控制.该系统在实验室局域网上通过测试,图像质量良好,系统运行稳定.

Design and implementation of a digital video monitor system based on ARM7 are presented in this paper. The MPEG-2 compression standard and corresponding control functions are the main characteristics of the system. The structure, composition and function are briefly introduced. (Emphases) are laid on the implementation of fast network transmission on a low performance ARM7. This system has been tested in the laboratory LAN with good image quality and stable system (performance.)
