Navigating the Challenges of Bandwidth Management in a Competitive Landscape

As bandwidth demands soar due to the proliferation of high-definition content and competitive offerings from fiber and satellite operators, effective bandwidth management becomes crucial. This report explores the complexities of current bandwidth systems, the high occupancy of spectrum by video services, and the pressing need for greater efficiency in video delivery. With the shift towards digital and on-demand services, operators must implement strategies such as switched digital video and adaptive bitrate streaming to manage bandwidth effectively while enhancing user experience and service offerings.

  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…
