摘要
在分析远程监控系统中图像传输特点的基础上,对图像远程实时传输中传输协议、传输方式的选择进行讨论,并针对图像实时传输中存在的延时、抖动、失真等问题,详细论述了采用多缓冲区循环、多线程及双缓冲技术实现图像实时、平稳传输的方法,并给出了基于UDP的实时图像多目传输的Java实现方法.实践证明,文中介绍的技术能有效地实现远程监控系统中图像的实时、高质量传输.
Based on analysing the features of image transmission in the remote supervisory system, discusses the selection of transmission protocol and transmission mode in the course of remote image real-time transmission, and specially focuses on the problems, such as delay, jitter and distortion occur in the course of image real-time transmission. It specifies techniques including multi-buffer circulating, multi-thread and double buffering to provide stable image real-time transmission, presents the implementation of image multicast based on UDP in Java. Experiments prove that the techniques introduced can provide high quality real-time image transmission for remote supervisory system effectively.
