Microsoft PowerPoint - Fleig_IPTV_G2

  1. 1. Campus Perspectives on IPTV David W. Fleig, Computing & Information Technology Merit Annual Conference June 2007
  2. 2. Definitions • IPTV – Extension of cable or satellite system – Requires a carefully conditioned network • IP Video – Broader definition • Both – IP encapsulation and transport – May use multicast or unicast Merit Annual Conference June 2007
  3. 3. IPTV • IPTV is singular, unique • Extension of cable or satellite system – Traditional programming • TV’s, flat panels, etc. require set top box • Computers require desktop client (viewer) • Properly and carefully conditioned network – Especially in a multi-channel, multi-viewer environment Merit Annual Conference June 2007
  4. 4. IP Video • Different – May be a small or large system • % of network or netops utilization – Different things to different people • Broadcasters, Educators, Research, Corporate, Government, Defense, Finance, etc. – Teaching & learning, research, archiving or communications tool – Webcasting and distance learning special cases – VOD, entertainment – Coexistence on a LAN • Also requires carefully conditioned network – May include IPTV Merit Annual Conference June 2007
  5. 5. IPTV STB STB WAN WAN Programming IP Encoders Merit Annual Conference June 2007
  6. 6. IP Video VOD Server/Storage (Stored Programming) STB STB WAN WAN IP Encoders Variety of Programming Sources Video Portal Merit Annual Conference (Admin/Mgt) June 2007
  7. 7. Complex Reality Merit Annual Conference Source: Cisco Systems, Scientific Atlanta June 2007
  8. 8. Complex Reality Merit Annual Conference Source: Cisco Systems, Scientific Atlanta June 2007
  9. 9. Issues • Cost –IP vs. Legacy • Licensing and rights –Analog…Easy –Digital…Difficult Merit Annual Conference June 2007
  10. 10. Issues • Cost of IPTV ownership – 40 channels – $5K to $10K per channel / encoder – $200K to $400K – Computer-based • 5 year replacement cycle • Annual licensing fees – Network management • Real-time environment • Multicast • Test and measurement – Network Consumption Merit Annual Conference June 2007
  11. 11. Network Conditions Bandwidth Viewers Bandwidth Std Def Hi Def Merit Annual Conference Format June 2007
  12. 12. Multicast Bandwidth Viewers Bandwidth Std Def Hi Def Merit Annual Conference Format June 2007
  13. 13. Encoders • Appliance or Computer-based – MPEG 1, 2, 4, WM • MPEG 2 – 720 x 480 • MPEG 4 – 320 x 240 – Native to QT – WM • MPEG 2 or 4 • No Multicast – H.26x • H.264 – Very convenient and portable • Broadcasting • Proprietary Merit Annual Conference June 2007
  14. 14. H.264 • Universal player • Better quality, lower bitrates • aka MPEG 4 - Part 10 • ISO standard • SD and HD • Excellent for videoconferencing • Very promising Merit Annual Conference June 2007
  15. 15. H.264 • $30K+ per encoder – Broadcast quality – Constant frame rate – 30 fps + • 15+ DSP chips to encode • Evolving • Written for unlimited proc power • Modern, high speed computer to decode • Future – Video Furnace, Inc. • Custom silicon – VBrick, Inc. • $8K per encoder • 3 DSP chips – Others…probably the same Merit Annual Conference June 2007
  16. 16. Which way? • EchoStar (aka DISH Network) – Value proposal • Provide / Expand Headend – “No Charge” – Equipment and labor – Analog or QAM – Fiber transport – STB’s – Built to WSU specs • Tradeout - Multiyear contract – Educational rates – Negotiated ROI Merit Annual Conference June 2007
  17. 17. Digital Rights • Will you be classified as a cable operator? • Will you be fundamentally different than a cable company? • Concept and intent of the Franchise Agreement – Private for-profit company vs. public entity – Public interest test Merit Annual Conference June 2007
  18. 18. Digital Rights • IP Encoding – Programming from somewhere… – EchoStar • “…Can’t offer permission to IP encode DISH programming…” Merit Annual Conference June 2007
  19. 19. Digital Rights • So you want to build one… • Be careful what you carry and where you carry it… Merit Annual Conference June 2007
  20. 20. Copyright • Google buys YouTube • Viacom sues Google for “One Billion Dollars” Merit Annual Conference June 2007
  21. 21. Trends • K-16 – Would like more – Research, training, academic support • Broadcasters – Transport, switch and distribute – May not coexist well with others • Telepresence • Digital Cinema – 2K, 4K – 6 Gbps and up Merit Annual Conference June 2007
  22. 22. Camera • Network – attached • HD + • H.264? Future Lens Computer GigE+ CMoS Network Solid State Interface Merit Annual Conference Imager June 2007
  23. 23. Trends • Test and measurement – Real time, continuous QoS testing • Tektronix • Rohde & Schwarz • Harris – Multicast • Verification of on-time delivery • Verification of transport • Verification of quality – Transport and IP Merit Annual Conference June 2007
  24. 24. Trends • Ultra-HD – NHK Japan – Television to Telesense – 1 Million frames per second cameras – 7680 x 4320 – 32 million pixel imaging devices – 16x more detail – ITU-R BT.1769 Merit Annual Conference June 2007
  25. 25. The Game of the Century • IPTV • Triple Play – Video, Data, Voice • Recent Headlines – “Fiber Surges Worldwide” – “100 Megabit Nation” – “One Million Homes Connected” – “Slingbox - Consumers want technology that can turn a computer into a TV” – “Cable Giant Comcast Tries to Channel Web TV” – “AT&T, Verizon Deploy Broadband Fiber Locally” – “Subscription TV Providers Think Out of the (Set- Top) Box” Sources: The Wall Street Journal, Broadband Properties, National Association of Broadcasters Merit Annual Conference June 2007
  26. 26. What we’re doing • Wait on “locally-encoded” IPTV • Limited – OSTN • Student Channel – U of M IP HDTV MiLR Project – HDTV Videoconferencing – Legacy CATV system • IP-based tools • Drivers – Unique, specific applications • Foreign language, Medicine • More IP Video than IPTV Merit Annual Conference June 2007
  27. 27. OSTN IPTV Receiver Parts and Cost Sun x2100 Server $1,580 Matrox G550LP Video Card $183 Edirol UA25 Audio Interface $239 TurboLinux 10f Software $79 APC UPS $690 Total $2,771 Merit Annual Conference June 2007
