  2. Objective • Use existing infrastructure/technology for • Access • Transport • Video encoding • Authentication • Billing To provide Television services (Live & VoD) to consumers. Rajesh J. Vale Department of Computer Science 2009

  3. Access • Wireless feasible? • xDSL • 512kbps, 768kbps etc is inadequate • Solution? • Fiber to home • Fiber to neighborhood • Mobility Vs Nomadicity • Mobility: Point of attachment changes in-session Rajesh J. Vale Department of Computer Science 2009

  4. Transport • Efficient way of transporting in IP layer • Broadcast TV (bTV) • VoD • Live-Pause TV or Network PVR • bTV natural candidate for Multicast • VoD for Unicast • Live-pause TV? Rajesh J. Vale Department of Computer Science 2009

  5. bTV: Multicast Issues • What about lost packets? • Retransmission • FEC • Interpolation • Is there such a thing as ‘reliable multicast’? • Multicast tree administration? Rajesh J. Vale Department of Computer Science 2009

  6. Video Encoding • Group of Pictures (GOP) • GoP size varies over time • Average with variance bounds exists • I/P/B frames • Transmission sequence : IBBPBBPBBPBB • CBR Vs VBR • CBR is preferred for predictability and efficient network engineering Rajesh J. Vale Department of Computer Science 2009

  7. bTV: QoE • Channel surfer experience • Load on network • Immediate channel change • How to overcome wait for I-Frame? • Smaller GoP encoding • Start from previous I-Frame • Catchup? • Create I-frame on request • How network knows I-frame carrying IP packet? Rajesh J. Vale Department of Computer Science 2009

  8. VoD • Buy now, watch anytime in next 30 days • Trick mode operations • Pause/FF/Rew • Content theft prevention • DRM system on top of every content flow Rajesh J. Vale Department of Computer Science 2009

  9. Authentication • Identity levels • Household • Individual • Avatar • How to use existing AAA infrastructure? • Limitations • 802.1X, SIM card, PKI certificate… Rajesh J. Vale Department of Computer Science 2009

  10. Billing • Online billing • Non-IPTV services • Offline billing • Traditional billing Rajesh J. Vale Department of Computer Science 2009

  11. Future IS/IT IP address is associated with viewer. Leverage it for unique services • Websurfing/shopping • Targeted Advertisements • Interactive TV • Blended services • Caller ID on TV • E-mail alerts WEBSERVICES Rajesh J. Vale Department of Computer Science 2009
