基于PSTN的视频传输技术研究

Study of Video Transmission Technology Based on PSTN

简单介绍了基于不同传输网络的视频编码系列及其符合ITU-TH.324协议在PSTN网上的实现比较。在PSTN网络上,提出一种中心基于PC,远端基于改进的H.263编码,采用通用数字信号处理DSP芯片的远程视频监控系统方案。

This paper briefly introduces video coding series based on various transmission networks and compares realization of protocol in accordance with ITU - T H. 324 base on PSTN. Moreover, a remote video monitor system is put forward, in which DSP base is adopted and the center of which is based on PC and the terminal is based on the improved H. 263 coding .
