Design And Implementation Of Real-time Audio And Video Recording And Streaming Publishing System

In recent years,the rapid development and popularity of the Internet provide a powerful market motivity for the streaming media business development.The improvement of network bandwidth provides a stable high-speed channel for real-time video transmission.Streaming services are becoming increasingly popular.Online video on demand and live video make people's life more colorful.Multimedia news conference makes people access to news faster and more conveniently.Especially,distance education is popular in recent years.Large opening online courses help those who can't realize the dream of learning in the classroom,so that children in remote areas can also enjoy high-quality education;telemedicine allows patients living in remote areas and do not have good medical condition to get a good diagnosis and treatment.Application of streaming media technology will not only bring revolutionary changes in information exchange network and bring great convenience for people's life but also have a profound impact.This article comes from a research project of their actual software development project.The goal is to design a kind of video recording and streaming media system that can be implied to the programs directed Taichung live audio.The main features of this system are showed as follows:according to the network conditions and dynamic change,it can adjust the video compression parameters and be controlled by remoting command.Good interface and remote control module can be easily integrated into other systems.Architecture of the system learns MVC hierarchical model in the overall module division.It divided the system of service,the logical of control and the data processing that reducing the coupling of the system.The data processing,drawing on ideas DirectShow multimedia framework,packages the individual processing unit as separate components so that it facilitates the simultaneous development of each module and contributes to the effective positioning problems.From the final results,the system has completed the functions about real-time capture high-definition audio,video signals in real-time audio and video compression,audio and video files locally synthesis,streaming audio and video distribution and so on.It achieves the desired effect of the product.It has a certain significance for real-time audio and video recording and streaming media distribution system.
