Abstract

In order to promote the automatic operation of Steel Works, the image of important production process should be monitored. The paper presents an entire remote image surveillance system based on multicast technology of network and image compression technology, describes the network construction of the system, and introduces the functions of system software. The local picture is compressed instantaneously by MPEG-4, and decompressed by client software, which is developed by Visual C++ on Windows 2000 platform, and multicast distribution of image is carried out by using IP multicast technology. The paper also discusses the realization of IP multicasting flow based on Winsock. The practical application shows that the system meets the needs of production process monitoring with higher compression ratio and wider bandwidth.
