基于WebRTC技术的诊后医疗系统实时通信研究

摘要

WebRTC技术的出现提出了实时音视频处理的解决方案, 所具有的开放标准为研究实时音视频的处理流程提供了技术依据. 通过对WebRTC的核心音视频操作库进行研究, 将WebRTC的技术方案应用于诊后医疗系统的在线问诊模块, 用以提升线上问诊服务的音视频质量. 通过对实时通信进行研究并依托WebRTC协议的通信体系结构, 设计了信令和媒体代理方案并最终实现了诊后医疗系统的实时通信.%With the advent of WebRTC technology, the solution of real-time audio and video processing was provided. Its open standards provide a technical basis for the further research of real-time audio and video processing. Through the research of the core audio and video operation library of the WebRTC, we apply the technical solutions of WebRTC in the online interrogation module of the post-diagnosis medical service system, to improve the quality of the audio and video of online consultation service. Through analyzing the communication of the core audio and video of the WebRTC and depending on the real-time communication architecture of WebRTC protocol, we design the scheme of signaling agent and media agent, and finally realize the real-time communication of the post-diagnosis medical service system.
