轻量级呼叫信号与点对点控制的WebRTC视频会议
Lightweight Call Signaling and Peer-to-Peer Control of WebRTC Video Conferencing
AI总结：
本研究提出了一种基于WebRTC的轻量级视频会议系统，通过点对点网络实现无需媒体服务器的多方视频通话功能。
摘要：
我们提出了一个基于网页的多方视频会议应用程序的软件架构和实现。它不使用媒体服务器。对于呼叫信号，它要么通过轻量级通知服务器利用现有的推送通知，要么利用电子邮件消息进一步消除该服务器的依赖。对于会议控制和数据存储，它在参与通话的客户端之间创建点对点网络。我们的原型客户端网页应用可以安装为浏览器扩展，或在桌面和移动设备上安装为渐进式网页应用。它使用WebRTC数据通道和媒体流，以实现具有音频、视频、文本和屏幕共享功能的完整视频会议。在创建我们的轻量级或无服务器系统过程中所面临的挑战以及所采用的技术，对其他希望在多方视频通话上节省服务器维护成本或付费订阅费用的低端WebRTC应用程序具有参考价值。
英文摘要：
We present the software architecture and implementation of our web-based multiparty video conference application. It does not use a media server. For call signaling, it either piggybacks on existing push notifications via a lightweight notification server, or utilizes email messages to further remove that server dependency. For conference control and data storage, it creates a peer-to-peer network of the clients participating in the call. Our prototype client web app can be installed as a browser extension, or a progressive web app on desktop and mobile. It uses WebRTC data channels and media streams for the control and media paths in implementing a full featured video conferencing with audio, video, text and screen sharing. The challenges faced and the techniques used in creating our lightweight or serverless system are useful to other low-end WebRTC applications that intend to save cost on server maintenance or paid subscriptions for multiparty video calls.
