摘要
水体污染的控制与治理是我国的重要课题,为弥补水域远程监控功能的缺失,提出基于3G网络的船载视频传输及保障系统,阐述了系统构成与层次结构,分析了3G网络视频传输的特点,并提出了简单的可靠用户数据报协议,实现了基于3G信道、H.264视频编解码、QoS控制的视频传输。实验结果表明系统可行,视频流畅,可应用于水域远程的实时视频监控。
The control and treatment of water pollution is an important issue in China.To meet the lack of remote monitoring of water,the ship video transmission and protection system based on 3G network was proposed.The structure of the system was described,and the characteristics of the 3G network video transmission were analyzed.The achievement of smooth real-time video transmission was based on 3G network,simple reliable user datagram protocol,H.264 video codec,and Quality of Service（QoS） control.The results show that the system is effective,and it can be applied to real-time video surveillance of water.
