流媒体技术在西气东输二线工业电视监控系统中的应用

Application of Streaming Media Technique in Industrial TV Supervisory Control System

流媒体技术是一种在数据网络上传递多媒体信息的技术,已被成功应用到工业电视监控系统中。西气东输二线工程的工业电视监控系统采用流媒体技术,大幅缩短了启动延时,当不同速率下的终端连入时,可以得到相应质量的播放效果。另外,流媒体技术中的数据缓冲技术,可以保持流媒体不间断,并保证数据传输的可靠性。特别是将P2P网络结构运用到流媒体技术中,有效地解决了带宽资源和网络拥堵问题,在使视频图像传输更畅通的同时能最大限度地节约带宽。

Streaming media technique is a kind of technology for transmitting multimedia information in digital network, which has been applied in industrial TV supervising control system successfully. The industrial TV supervisory control system of Second West to East Gas Pipeline Project uses streaming media technique that decreases greatly the start delay. As terminals with different speed rates are linked in, the corresponding display quality reaches. In addition, the data buffering of the streaming media technique can keep streaming media continuity and data transmitting reliability. In particular, the use of P2P network structure in streaming media technique solves effectively the problems of band width resource and network jam and achieves fluent video image transmission and maximum band width saving.
