摘要

在深海采样中,实时远程视频传输系统对采样设备的活动进行实时监控是十分必要的。为了克服光纤的脆弱性和其他有线无中继视频传输技术视频传输质量不高的问题,本文提出了一种基于SHDSL的10公里以上同轴拖缆的深海无中继视频传输系统。该系统由视频服务器、SHDSL调制解调器和传输介质组成。现场测试结果表明,本文系统的视频传输速率可达1590kbps,系统传输的视频质量良好,视频输出无明显的色彩和细节损失。

Deep-sea unrepeatered video transmission system over 10 km coaxial tow cable based on SHDSL
A real-time long distance video transmission system to keep a close watch on sampling devices' activities is very necessary to the deep-sea area sampling. To overcome the vulnerability of the optic fiber and the low-quality of the video transmission of the other wired unrepeatered video transmission technology, a deep-sea unrepeatered video transmission system over 10 km coaxial tow cable based on SHDSL is presented in this paper. The system is composed of video server, SHDSL modem and transmission medium. The results of the field tests show that the video transmission rate of the system in this paper can achieve up to 1590 kbps, the quality of the video transmitted by the system is good and there is no obvious color or detail loss in the video output.
