摘　　要：基于网络的数字视频传输技术得到广泛的重视和应用。作者结合煤矿工业电视监视系统的实际,设计了一种基于RTP(real-timetransportprotocol)的煤矿数字视频监视系统模型,在文中介绍了该模型及其关键技术,并提出了一种具有自适应功能的丢包修复技术AFEC(adaptiveforwarderrorcorrection),测试结果验证了该技术的有效性。The digital video transmission technology based on network arouses people's attention widely.Aiming at the present status of TV-monitoring system for coal mine,a digital video monitoring system model over RTP is designed in this paper.The key technology is introduced in detail,and a new AFEC technology for recovery missing packets with self-adjustability is brought forward based on the analy-sis of the QoS technology.Testing results show the effectiveness and correctness of this approach.
