Research And Implementation Of Video Communication System Based On WebRTC

In our daily life,the use of video communication technology has been very extensive.It not only provides us with great convenience in ordinary communication,but also applies in the fields of education,medical treatment,management and so on.Video communication technology is also varied,each has its own advantages and disadvantages.Video communication software and plug-ins are also multifarious.Although the development of video communication technology is very rapid,there are still many problems,such as the adoption of different intercommunication by private protocols,the penetration of internal networks and firewalls,and the incompatibility of multiple platforms.WebRTC real-time communication technology has been paid attention to since it was launched by Google Corporation as open source.It has become an important technical choice for many people to realize video communication products.Later,WebRTC technology has been incorporated into the W3C standard,and the use of this technology is more widely and highly favored.This article is based on WebRTC technology to realize the web version of the video communication function,and can provide real-time video communication services to other third party applications.In this paper,through a certain research and analysis of the architecture of WebRTC technology,we know how WebRTC is how to obtain and decode audio and video data,how to establish the network connection between video terminals and how to carry out the transmission of media data.On the basis of the JavaScript video communication interface and the signaling management mechanism provided by the WebRTC,a room model for real-time video communication is proposed.All the people in the room do not have equal status and authority,and control the audio and video data of some people through the authority of the room administrator to save the resources.The model has some limitations,but it has relatively good effect for a specific case.Finally,through the practical use of telemedicine system to the video service provided in this paper,the availability and practicability of the video service provided in this paper are verified to a certain extent,which basically meets the needs of the telemedicine system and achieves the expected effect.
