The document discusses WebRTC and its advantages for real-time communication over the web. WebRTC allows web browsers to communicate in real-time through simple JavaScript APIs without requiring plugins. It has a simple architecture using APIs for accessing cameras, connecting to other users, and transferring data like files. WebRTC provides an easy way to build video chat and other real-time applications using only a few lines of code. However, some browsers have not fully implemented WebRTC APIs yet.

1. HAPPY NEW YEAR
May this year bring a new
change in your life that you
always wished to have.

2. Why ,are we here ?

3. Web real time communication

4. Why Webrtc ?
 Webrtc is a free, open project that enables web browsers with real-time





communication(RTC) capabilities via simple javascript APIS
No plugin required
(i,e need not install and configure software everytime)
Platform and system independent
Just need to have the latest version of chrome / mozilla
(i,e clients are our web browser.)
User and developer friendly , video chat experience can be built
using 100 lines of JS code

5. Architecture & Working
 Simple architecture ready to use APIs
1. getUserMediaStream API
- for accessing webcam and microphone
2. PeerConnection API
-connecting to other end user(remote peer)
3. Datachannel API
- screen sharing , gaming , text chat ,file transfer

8. Working

 Diagramatic explanation

9. keywords used in slide
 SIP: Session Initiation protocol
 SDP : Session description protocol
 ICE : Interactive connectivity establishment
 NAT : Network address Translation
 TURN : Traversal using relay around NAT
 STUN : Session Traversal utilities for NAT
 SRTP : Secure real time transport protocol
 Codec: compressing and decompressing data for effective utilization of
bandwidth


Need to implement signalling for connecting 2 browser
Apple web-browser Safari yet to support webrtc APIs . We might
need a native app on IOS platforms
Internet Explorer (IE) is building its own Webrtc APIs named
CU-RTC-Web
Various browsers use different APIs for WEBRTC implementation

19. browsers supported at present
