基于改进UDT协议的实时视频传输

Real-time Video Transmission Based on Improved UDT Protocol

提出了一种基于改进UDT协议实时视频传输的协议算法,研究了使用该种改进协议进行实时视频传输的效果及性能,并与使用UDP协议和UDT协议进行实时视频传输进行了对比,发现使用UDP协议传输视频质量较差,会出现花屏的现象,使用UDT协议传输延时较大,对实时视频传输来说是不可接受的。因此需要对UDT协议做出改进,使得其在传输实时视频的时候可以有一个较好的表现。

This paper presens a method of real-time video transmission based on improved UDT protocol and studied its effect and performance. And compared with transmitting real-time video by UDP protocol,the quality of video by using UDP protocol to transmit real-time video was a little bad,it may appear blurred screen.And compared with UDT protocol itself,the delay of transmission was too large.In order to adjust to transmitting real-time video,the UDT protocol should be improved.
