  1. A Service Oriented Architecture for a Multi Channel Internet TV System Md. Tanvir Al Amin tanviralamin@gmail.com (Presenter) Imranul Hoque imranulhoque@cse.buet.ac.bd, Md. Yusuf Sarwar Uddin yusufsarwar@cse.buet.ac.bd Department of Computer Science and Engineering, Bangladesh University of Engineering and Technology, Dhaka, Bangladesh.

  2. 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 3Objectives • Robust • Inter - Operable • scalable

  5. Proposed Architecture 3 System Components 1 TV Broker Server (TBS) 2 TV Program Server (TPS) 3 Internet TV Client (ITC)

  6. TV Broker Server (TBS) TPS ITC TBS Service Tree (Local) Fig : Work Load of the Broker Server

  7. TV Program Server (TPS) Architecture of TV Program Server

  8. Internet TV Client (ITC) Query Multicast in LAN Message TBS 1:1 Share Feedback Transmission ITC TPS Fig : Work Load for an ITC

  9. Communication Setup Blue : Channel 1 Green: Channel 2 Magenta: Channel 3 Red : Control Between TBS and TPS Black: Control between TBS and ITC

  10. Legend B,G,M TPS a,b,c,d,… ITC Service Tree Management A Hypothetical Service Tree at a moment

  11. Legend B,G,M TPS a,b,c,d,… ITC Service Tree Management Some new node arrives into scenario

  12. Legend B,G,M TPS a,b,c,d,… ITC Service Tree Management Some node changes service status

  13. Legend B,G,M TPS a,b,c,d,… ITC Service Tree Management After a network Reorganization (Periodical)

  14. Sequence of Action Get TV Program Get Service Node Authenticate Get Service Nodes Service Request Compute Cost Get Service Param Adjust Service Tree Select Service Node Provide Node List ITC Self TBS Self Self STM TPS

  15. Success of Our Architecture • Web Service dependent. • Easily Deployable • Dynamic Quality Management • Hassle free Client side

  16. Transmission Not Optimal Security Not Considered Propagation Delay Limitations
