  4. Agenda • Introduction • Scenario • Requirements • IPTV Architecture • IPTV over Internet2 • Final Considerations • Acknowledgments Fall 2006 Internet 2 Member Meeting

  5. Introduction • What is IPTV? • TV Channels over the Internet ? • Video streams encapsulated in IP packets over a “service provider” network ? • Will Internet support a High Definition IPTV Service? “Internet no ready for its future roles” (Bill St. Arnaud) Fall 2006 Internet 2 Member Meeting

  6. Scenario • High Definition Streamings (HDTV) • Typically, 25 Mbps per TV Channel for MPEG2 encoding. • Multiple channels sent simultaneously to multiple receivers at a same location. • A home with three TV sets would require at least 3 x 25 Mbps. Fall 2006 Internet 2 Member Meeting

  7. Scenario • IPTV requires high levels of: • Quality of Service (QoS) • Quality of Experience (QoE) … at least on par with analog or digital TV broadcast system. • Access networks technologies like xDSL do not support high definition IPTV services: • VDSL has bandwidth and distance limitations. It achieves 50Mbps at 300m. Fall 2006 Internet 2 Member Meeting

  8. Scenario • Currently, FTTH (Fiber-To-The-Home) services seems to be the only one alternative for the fulfillment of IPTV (HDTV) needs • PON (Passive Optical Network) presents itself as the most viable FTTH technology, both from economical and operational standpoint • WDM-PON can provide 100Mbps fiber connection far beyond 300m – around tens of kilometers) Fall 2006 Internet 2 Member Meeting

  9. Requirements • Security • Content protection: protection of the intellectual property of the content owner, while allowing fair use for the final user. • Service protection: authentication, confidentiality and access control. Fall 2006 Internet 2 Member Meeting

  10. Requirements • Quality of Experience (simple and convenient handling): • Multi-channel. • Zapping. • Infrastructure: • Availability (at least on par with analog or digital TV broadcast system). • Accessibility (diversity of devices – e.g. PCs, Set-Top-Boxes). • Network/Application scalability. Fall 2006 Internet 2 Member Meeting

  11. IPTV Architecture Fall 2006 Internet 2 Member Meeting

  12. Architecture Entities • Head-End: provides IPTV services (Broadcast TV and VoD). • Transport Network: delivers video streams to the customers. • Customer Premises: broadband network termination. Fall 2006 Internet 2 Member Meeting

  13. IPTV Architecture: Head-End • Broadcast TV Head-End system: • Receives an analog or digital signal via satellite or other mean, typically with multiple transport streams. • Converts it to a series of single program streams. • Encodes or transcodes the signals (e.g. to MPEG-4 format). • Encapsulates streams in IP packets for transmission. • Sends streams to a specific IP multicast group Fall 2006 Internet 2 Member Meeting

  14. IPTV Architecture: Head-End • VoD (Video-On-Demand) Head-End System: • Encapsulates video streams in IP packets. • Sends streams to the users. Fall 2006 Internet 2 Member Meeting

  15. IPTV Architecture: Transport Network • Core Network: • High capacity optical network with technologies such as IP over DWDM and MPLS/GMPLS. • Edge Network: • Multicast enabled network that connects the core network to the access network. • Access Network: • It is a FTTH-PON (Fiber-To-The-Home Passive Optical Network). Fall 2006 Internet 2 Member Meeting

  16. IPTV Architecture: Customer Premise • Provides broadband network termination functionalities. • It is the IPTV service client. • The heterogeneous technologies existing in a home network devices lead to the need for a robust Home Gateway to connect it, providing the necessary services. Fall 2006 Internet 2 Member Meeting

  17. Multicast X Overlay • Overlay tries to provide multicast functionalities at the application layer: • It is still a immature solution to provide a reliable and QoE enabled service for High-definition content with scalability. • Multicast is proven to be a more efficient distribution scheme with scalability. • This work proposes an auto-contained, controlled private network: • Internet does (still) not provide the required levels of availability, scalability, QoE and QoS. Fall 2006 Internet 2 Member Meeting

  18. IPTV over Internet 2 Demonstration • Creation of an infrastructure for High Definition Streamings (HDTV) support • Specification and performance evaluation of high definition video distribution experiments Fall 2006 Internet 2 Member Meeting

  19. IPTV over Internet 2 Demonstration Fall 2006 Internet 2 Member Meeting

  20. Infrastructure • Comprised of three sites: • LARC – Ericsson IPTV Infrastructure • Content generation • Multicast distribution • III Workshop TIDIA – KyaTera • Content consumption • International partners • Content generation, • Multicast distribution • And/Or Content consumption Fall 2006 Internet 2 Member Meeting

  21. Content Distribution Fall 2006 Internet 2 Member Meeting

  22. Content Distribution • A hybrid topology • Physical routers • 2 Juniper routers with 2 x 1Gbps interfaces • Emulated routers • 6 emulated routers with XORP (eXtensible Open Router Platform – http://www.xorp.org) • This topology will be set up in a server with Linux virtual machines (VMWare) and XORP • All routers will be multicast enabled (PIM-SM – Protocol Independent Multicast – Sparse Mode) • Minimal of 100 – 200 Mbps bandwidth links interconnecting the three sites • Minimal of 1 Gbps bandwidth links interconnecting the routers in the multicast network Fall 2006 Internet 2 Member Meeting

  23. Content Consumption Fall 2006 Internet 2 Member Meeting

  24. Content Consumption • Three clients with a Front End application over a VLC Client • Two clients connected to TVs • One client with a Media Player (though EPG – Electronic Program Guide) • Basic functionality of the Front End application: zapping among multicast groups • A supervisor station that monitors the network to demonstrate some behaviors (link bandwidth, routing tables, multicast protocols, and so on) Fall 2006 Internet 2 Member Meeting

  25. EPG (Electronic Program Guide) Fall 2006 Internet 2 Member Meeting

  26. IPTV over Internet 2 Demonstration: EPG (Electronic Program Guide) Fall 2006 Internet 2 Member Meeting

  27. Final Considerations • IPTV over Internet2 • HDTV over Internet with stringent QoS and QoE requirements it is not possible in the current infrastructure. • Due to QoE requirements (e.g. zapping), a bandwidth of hundreds of Mbps per service user (per subscriber) is required.
