Editor's Notes
- #3: With the advent of unlimited channels, unlimited applications, unlimited news, unlimited information and unlimited entertainment — why are we feeling more isolated? Has the technology of connecting human beings and ideas only begun to tap into fulfilling the most fundamental human needs? Even as we are living through a transitional period where we are now able to instantly “attach” to other people and ideas, why are we longing less for “instant messaging” and more for “meaningful messaging?”
- #7: If you're not familiar with WebRTC, it's the technology which will cause the next drive towards mass adoption of voice, video and file collaboration. In essence, it will enable high quality video and audio in your web browser, which is one of the most deployed applications in the world. It has been drafted by W3C (World Wide Web Consortium) with protocol work done by IETF (Internet Engineering Task Force). WebRTC ultimately simplifies the incorporation of real-time communications into a web browser. The objective of WebRTC is to trigger a real-time session in your browser, without having to download anything, simply functioning as part of the normal operation of browser. Everything required to deliver a high quality experience at the endpoint is supported natively within a WebRTC-capable web browser.
- #9: WebRTC defines several APIs together with a collection of communication processes and protocols. From a development perspective, core functions are encapsulated into three main JavaScript APIs: getUserMedia, RTCPeerConnection and RTCDataChannel. These APIs are incorporated into browsers that support WebRTC, hence a web developer who has JavaScript programming experience can bring an interactive video collaboration experience to the web. WebRTC allows a mesh-based technology to enable users to send and receive streams to and from each other.
- #10: Although WebRTC isn't confined solely to web applications, embedding real-time communications directly into web browsers has been the focus for most of the industry. With WebRTC it becomes possible to embed real-time video into a range of vertical applications, including for business, medical and education purposes.
