3G 带宽叠加技术在河口管理中的应用

摘要

On the basis of the public network, the practical speed of 3G network among the Zhangwei river south bayou area is about 400kbit/s. However, the traditional monitoring system that based upon the public 3G network is not able to afford transmission of high-definition (D1 and higher resolutions) videos. For the need of normative law enforcement for the water administration and supervision, it is necessary to uses 3G bandwidth fusion technology, combining the classic 3G network video structural frame. It expounds the working principle and realizes image collection and transmission of high-definition images.%受公网覆盖的影响，在漳卫南河口管理区域的3G实际速率在400 kbit/s左右，传统的基于3G网络的监控系统无法传输高清晰度（D1及以上分辨率）的视频。为满足河口水政监察规范执法的需要，结合典型的3G网络视频架构，采用了3G带宽叠加技术，阐述其工作原理，实现高清晰度的图像采集和传输。
