What is an Internet TV

• System for Real time transmission and Reception
  of TV Programs.
• Low Cost Approach, no external setup.
• Easy initiation of new Channels.
• Can Target Clients anywhere, all over the Globe.

3
Existing Solutions

• RTP / RTSP for Transmission
• MBone dependent Solutions
• Owned Solutions by some company
• But
• There is a lack of Robust, Scalable and
• Inter- Operable Architecture in this field.

4
Challenges for Our System

• 3 Objectives
• Robust
• Inter - Operable
• scalable
