The success of video conferencing using WebRTC heavily relies on 3 exclusive HTML5 APIs – RTCPeerConnection, RTCDataChannel and getUserMedia-which combine to capture both audio and video information, trace other individuals to initiate communication with, and then transmit streaming content to another browser (peer).

These APIs are inbuilt and can be found in browsers such as Firefox, Opera, and Chrome. WebRTC makes use of audio codec Opus and video codec VP8 to provide industry-leading streaming abilities.

The VP8 (video codec) which is the key element in the video conferencing capacity of WebRTC comes with resolution limits and frame rates higher than typical monitors can attain. Users can even make use of this immediate streaming media without sacrificing on the all-important high-definition video. Moreover, VP8 is both open source and free which therefore means that there are no accompanying fees with WebRTC video conferencing.

Before delivery, all data transmitted through this video conferencing is comprehensively encrypted. This is performed through the use of Datagram Transport Layer Security (DTLS) - a characteristically standardized protocol. This encryption is common with every WebRTC supporting browser and is formulated to guarantee the secure transmission of data.

WebRTC provides complete encryption with message authentification, asymmetric cryptography systems, and data discretion to maintain the privacy of video data.
