Get local stream
using
getUserMedia()
Set LocalStream using:
Element autoplay=true;
Element.src=webkitURL.creat
eObjectURL(stream);
webkitRTCPeerConnection
Set remote Description by using:
peerConnection.setRemoteDescri
ptionremoteDescription);
Create offer using:
peerConnection.cre
ateOffer();
Conversation object
Create answer using:
peerConnection.createAnswer()

Challenges Faced
• Interoperability issues with the web browsers
• It leaves many details of session establishment to the end points to work
out on their own.
• Complexity in initiating Peer Connection
• Generating and Processing signaling messages
• Receiving the remote media stream
11
SUMMARY
• Developed web- based application for universities enabling real time communication
between students and professors
• Teaching cloud.com only involves web bowsers with Real-Time Communication
capabilities via simple JavaScript APIs and HTML5
• Group chat rooms.
• No Native Application downloads and Plugins.
Future Scope
• Setting up a data channel
• Integrating teachingcloud.com with existing applications
