PTV Landscape • Capital Needs • Interconnection • Infrastructure
![Page 9: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/9.jpg)
Capital Needs Current State
![Page 10: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/10.jpg)
PTV Capital Needs Assessment • Comprehensive survey of stations in 1Q2013
• Landscape:
– Reduction & elimination of PTFP, CPB Digital and RUS capital funding
– Aging infrastructure – Deferred maintenance – Shortening equipment lifespan – 10 year-old DTV infrastructure
![Page 11: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/11.jpg)
Capital Needs Today • > $600 million in backlogged projects
– $200 million in towers, many > 40 years old – $200 million in studio & production gear – $200 million in other infrastructure
![Page 12: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/12.jpg)
5-year Capital Needs • Essentially every station is facing at least $1
million need in next 5 years • 50% of stations are facing at least $3 million
in next 5 years • 42 rural analog translators need conversion
![Page 13: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/13.jpg)
And the spectrum repack? • Lots of unknowns • Will the repack funding be sufficient? • Will we do this with ATSC 1.0? • What are the tower implications?

Infrastructure Current State
![Page 23: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/23.jpg)
Infrastructure - Historical • Hardware-centric:
– “Rack and stack” – Highly specialized / customized – Tightly coupled – Narrow standards – Relatively long life cycles
![Page 24: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/24.jpg)
Infrastructure - Today • Becoming software-centric
– Rapid blending of IT and Internet technology – Shifting toward commodity, multi-vendor,
virtualized and software-based systems • Shortening life cycles • Mostly separate broadcast, IT and non-
broadcast systems
![Page 25: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/25.jpg)

![Page 28: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/28.jpg)
Journey to the Future • Standardize • Commoditize • Virtualize • Automate • Consolidate • “Pull” content model • Cloud
![Page 29: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/29.jpg)
A new era of Interconnection:
IXCv6
![Page 30: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/30.jpg)
IXCv6
• Starts October 1, 2016
• Following PTV history and legacy it should be: – Transformative – Innovative – Industry Leading – Efficient
![Page 31: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/31.jpg)
IXCv6 Plan • Approach validation FY13 • Technology validation / lab FY13/14 • Station validation FY14 • Capitol Hill FY14/15/16
![Page 32: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/32.jpg)
IXCv6 initial analysis / lab work • Assumptions:
– Serve all stations – Terrestrial MPLS networking – 100 Mbps objective, 45Mbps in hardest cases – Linear “Push” feeds – NRT and soft-feed “Pull” content – RT linear satellite feed for DR and reach
![Page 33: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/33.jpg)
What size pipes are required?
100 Mbps
![Page 34: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/34.jpg)
What is the reach to stations? • Fiber connectivity today:
OnNet, 12
NearNet, 102
Offnet, 57
Station Connectivity
100 Mbps Ethernet, 122
DS3 (45Mbps) Affordable, 41
DS3(45 Mbps) Expensive, 9
Connectivity Type
![Page 35: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/35.jpg)
Is it affordable? • VERY Preliminary, but:
– Initial answer is YES – Lower cost than a straight NGIS replacement – Joint master controls also reduce cost (but
shift some connectivity costs to stations) – Offers significant station opportunities for cost
reduction through opt-in cloud services
![Page 36: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/36.jpg)
What about Ultra-HD? • We assume the likelihood of Ultra-HD / 4K
in a ten year window for IXCv6 • Also assume 2x compression technology
advances, HD and SD will still exist
![Page 37: John McCoskey - PBSbento.cdn.pbs.org/hostedbento-prod/filer_public/2013/04/...“a point on a curve at which the curvature or concavity changes sign” I talked a lot last year about](https://reader033.vdocuments.us/reader033/viewer/2022041605/5e338e23f83b322a112d7de5/html5/thumbnails/37.jpg)
