3. What is WebRTC?
4. Characters of WebRTC 1. Plugin Free
 Many web services already use RTC, but need downloads, native apps or plugins.
 Skype, Facebook, Google Hangouts 2. Fast 3. Convenient
 No download, no install, no update. 4. Easy Maintaining
 No need to deploy, debug, test and maintain plugins
5. WebRTC Architecture
6. Main 3 categories of APIs provided by WebRTC MediaStream (aka getUserMedia)
 get access to data streams, such as from the user's camera and microphone. RTCPeerConnection
 audio or video calling, with facilities for encryption and bandwidth management. RTCDataChannel
 peer-to-peer communication of generic data.
7. MediaStream: getUserMedia
8. RTCPeerConnection 1. creates an RTCPeerConnection object with an onicecandidate handler 2. sends serialized candidate data through signalling channel 3. exchange session description(SDP, JSEP)
9. Signalling channel and WebRTC
10. RTCDataChannel General Data Communication Act like WebSocket Use Cases Gaming Remote desktop applications Real-time text chat File transfer
11. Compatibility Currently supported by Chrome, Firefox and Opera Browser supports WebRTC only means that it at least implements MediaStream Apple Will Soon Support WebRTC 
 The team is merging WebRTC related code from Blink to WebKit Microsoft Internet Explorer is a tough nut to crack
12. Cases Tokbox (aka OpenTok, https://tokbox.com/)
 Real-Time video communication service provider InstaEDU (https://instaedu.com/)
 Based on OpenTok, provided online classrooms with video chat capacity Ericsson Researches (http://www.ericsson.com/research- blog/) Experimental WebRTC mobile browser Field Service Support with Google Glass and WebRTC Limitless Imaginations
