  1. Bandwidth Management: A Conundrum Bandwidth Management Systems September 2010

  2. Competitive environment • Fiber service operators • Lots of Bandwidth • Lots of MPEG-4 HD • High data rates • VOD • Satellite service operators • MPEG-4 HD • Lots of HD • No data • Push VOD • Over the Top providers • use our infrastructure for free • LOTs of content • High speed data (ours) • Social networking 2

  3. Competitive environment • Bundles still the big draw • Video, Data and Home phone • And now Cell phone, PDA, etc • “Churn” Drivers • 150-200+ HDs Paramount (and starting to be 3D) • Guide, presentation and user friendliness • Multi-room DVR • Data, High speeds • VOD, number of hours, number of “free” and HD titles • Retention Drivers • Trusted provider, i.e. straight answers, customer service, reliability, LISTENs to what the customer wants • More and/or better of all of the above churn factors 3

  4. 153 QAMs 135 QAMs <-860MHz 1GHz-> Unless you make the spectrum more efficient there is little room to add services

  5. Bandwidth needed: Where to get it? • 90%+ of the Spectrum is occupied today by video • Less than 10% other services (DOCSIS, telephony, control, carousel, etc) • Where indeed??? • So how to do that…. Video must become MUCH more efficient!!!!

  6. Multiple Simulcasts (Plant Percentages) 6MHz slots (“QAMs”) Used 860MHz Plant 1GHz Plant • Analog 70-80 55% 49% • to Digital SD (MPEG-2) 7-8 6% 5% • to Digital HD (MPEG-2) 35-40 28%25% 89% 79% • to MPEG-4 AVC HD 16-20 13% 12% • Traditional to IP 10-11 8% 7% • Linear to Time shifted ? • Linear to Adaptive Bitrate ? 110% 98% • Assumes base formats without bandwidth levers, e.g. no statmux, no SDV, etc. 6

  7. Bandwidth Levers Switched Digital Video (SDV) 2.8:1 Just in Time Service Group Segmentation 3 QAMs/yr MPEG-4 AVC HD (1G & SDV markets) 4.6:1 3:1 Statmux 1.5:1 Recover unused QAM B/W (FM, Above 860, etc) 2-6 QAMs Analog Reclamation 2-3 QAMs/yr Just in time VOD & DOCSIS support Varies Future ideas QAM Sharing Video over IP 1024QAM Deep Digital or All Digital Reduce “legacy” multi-formatted channels: SD, Linear? Efficiency Increase 7

  8. Bandwidth Efficiency (Multiplier) MPEG-2 MPEG-4 AVC Frame Compatible Frame Packed 6MHz Broadcast Simulcast Statmux SDV Broadcast Simulcast Statmux SDV 1 -1 Analog 10 -.1 1.5 2.8 SD 2 -.5 1.5 2 2.5 -.2 4 9* HD 2 -.5 6** .8 5** 3D 4+ -.13 Video Over IP Assumes min. 4 Bonded channels; 300ms buffer in Settop * Due mostly to few settops able to receive MPEG-4 AVC **Assumes few 3D viewers as yet, when Frame Compatible that advantage is gone 8

  9. Bandwidth Efficiency (Channels) MPEG-2 MPEG-4 AVC Frame Compatible Frame Packed 6MHz Broadcast Simulcast Statmux SDV Broadcast Simulcast Statmux SDV 1 -1 Analog 10 -1 15 28 SD 2 -1 3 4 5 -1 8 18* HD 2 -1 12** 1.6 10** 3D 8+ -1 Video Over IP Assumes min. 4 channels bonded; 300ms buffer in Settop * Due mostly to few settops able to receive MPEG-4 AVC **Assumes few 3D viewers as yet, when Frame Compatible that advantage is gone 9

  10. Spectrum Usage (860MHz plant) 135 QAMs 10

  11. Spectrum Usage (1GHz plant) 153 QAMs

  12. End Point (2018+) • 9-11 Analog Broadcaster Channels->eventually no analog • Digital Content format • Linear Content: Live Sports only • Time shifted content: All other (Broadcast, Movies, etc.) • IP throughout the home (80% Video, 20% Data) • IP settop • Handheld (mobile, nomadic) • PCs • Video Gaming • Marriage of Wireless and HFC? • Possibly MicroCells using Cable distribution 12

  13. Conclusion No matter how big the pipe, new services will grow to oversubscribe it: Bandwidth Management has no end…

  14. Thank You • Any Questions?
