Bandwidth Management:

A Conundrum

Bandwidth Management Systems

September 2010

competitive environment
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

competitive environment1
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

153 QAMs

135 QAMs

<-860MHz

1GHz->

Unless you make the spectrum more efficient there is little room to add services

bandwidth needed where to get it
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!!!!

  • 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.

bandwidth levers
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

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

end point 2018
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

conclusion
Conclusion

No matter how big the pipe, new services will grow to oversubscribe it:

Bandwidth Management has no end…
