ORTC (Object Real-Time Communications)
[Some information relates to pre-released product which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.]
ORTC (Object Real-Time Communications) enables media (audio and/or video) to be streamed (sent and received) in real-time directly between web browsers, mobile devices, and servers via native Javascript APIs.
Note Microsoft Edge now implements ORTC for Windows 10 devices. However, this implementation differs from the most recent version of the ORTC API. ORTC has continued to evolve since the development and release of Microsoft Edge -- the browser does not implement every object or method within the ORTC API, and includes extensions not currently incorporated within the specification. Further development will continue with the goal to enable developers around the world to build experiences that include the ability to talk to Skype users and other WebRTC compatible communication services.
ORTC uses "sender", "receiver" and "transport" objects, which have "capabilities" describing what they are capable of doing, as well as "parameters" which define what they are configured to do. "Tracks" capture and encode media streams by senders, traveling over transports, then decoded by receivers that render the media stream tracks to video/audio tags.
