基于WebRTC应用层网关在iOS端的设计与实现

Design and Implementation of iOS Audio and Video Transmission Based on WebRTC

随着近年来新媒体技术的快速发展,用户对实时音视频通信的质量要求越来越高.WebRTC技术的出现,以其强大的音视频处理引擎迅速占领市场,对多媒体通信行业产生了巨大的影响.然而WebRTC提供的JSEP仅仅能完成简单的媒体链接功能,在企业级的通信中需要结合其他模块或者信令协议才能胜任完整的应用.本文着重研究了WebRTC与SIP的互通问题,并在iOS端基于WebRTC技术设计实现了一种应用层网关,通过实验验证了该网关的可行性与实用性.

With the development of multimedia technology, and the real-time communication technology, people＇s requirement for real-time audio and video communication is higher and higher. The WebRTC technology emerges and occupies the market quickly based on its powerful audio and video processing engine, which has a huge impact on multimedia communications industry. WebRTC JSEP provided, however, can only perform simple media link function. It is required to combine with other modules or signaling protocol to do a complete application in the communication of enterprise. This paper focuses on the WebRTC communication with the SIP, and in the iOS terminal it designs and implements a kind of application layer gateway based on WebRTC technology. Finally, the feasibility and practicability of the gateway is verified with experiments.
