Bandwidth Management:

A Conundrum

Bandwidth Management Systems

September 2010

• 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

• 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

• 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.

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

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

153 QAMs

• 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

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

Bandwidth Management has no end…

• Any Questions?
