To support these interactive use cases, Real-Time Communication (RTC) solutions, as the open-source WebRTC framework, are generally used. ...
Particularly, we demonstrate how our framework can improve the received video quality up to 15% compared to an approach where the encoding bitrates are static and do not change over time. ...
In order to reduce the scalability issue of such a peer-to-peer architecture, we propose a WebRTC-compliant framework to support the delivery of real-time communication streams. ...
