压缩技术在实时信息系统中的应用

Application of compression technology in real-time information system

采用SVG网络实时发布信息,不仅能节省网络传输带宽、减少传输时延,而且能使图像随着实时数据的变化而变化。但是,当SVG图形复杂时,实时数据的网络传输量依然较大。文章介绍了实时信息系统的模型及几种压缩技术,提出利用压缩技术来减少网络数据的传输量。实验结果表明,与未进行压缩相比,压缩后实时信息的传输效率和性能明显提高。

Real-time information distribution system based on SVG not only reduces the transmission bandwidth and delay but also realizes the images change with real-time data. However, if graphic is complex, the volume of real-time data is still large. This paper introduces the models of real-time information system and some compression technologies, and puts forward the suggestion that reduces the amount of network data by using compression technology. The results show that the efficiency and performance of real-time system are improved significantly.
