实时视频网络传输系统实现技术

随着国际互联网的发展和信息化社会的不断进步,报纸作为一种传统的大众传播媒介,正经历着巨大的冲击与变革。因此,报纸行业纷纷与新兴的网络媒体相结合,组建自己的报纸网站,在其功能日臻完善的同时,逐渐占领并不断开拓更广阔的市场。作为一种新型的商业模式,报纸网站有着自己鲜明的特点,是一种正在对个人及社会影响越来越大的传媒形态。

Implementation of a Real-time Video Stream Transmission System

Research on the implementation methods of real-time video stream transmission systems is important for video application. In this paper,the block diagram of a real-time video network transmission system is provided.On this base,a detailed analysis of the key technology is made,which indudes video capturing, encoding and decoding system, network transmission control protocol (TCP).Especially, the emphasis is laid on video encoding technology for communication at the sending terminal, error concealment and error resilience at the receiving terminal, network transmission control protocol for providing QoS(Quality of Service). And then the embedded video transmission platform is designed by integrating the embedded operating system for providing a powerful, flexible and robust real-time video application.
