Research And Realization Of Real-Time Streaming Media Acquisition And Recording System

With the development of Internet, digital video recorder in distributive environment has gradually developed into network video recorder. Based on principles of streaming media receiving and related key technique, this paper presents a streaming media delivery method which can improve transmittion quality of streaming media, meanwhile designs and realizes a real_time high definition streaming media acquisition and recording System in IP network.By combining multi-threaded programming techniques and Live555project, the system solves the problem of multi-streaming media transmission. This method not only improves the utilization of resources, but also enhances the functionality of the network recorder. It can handle streaming media transmission better.This paper designs acquisition and recording module of streaming media, implements interaction of RTSP protocol and solves some+unusual problems such as dropped calls and timeout of network connection. In addition, it enables real-time transmission of H.264video data, and solves the problem of streaming media transmission jitter.
