NGIS Ground Segment

• The SRO provided stations with large dishes, 4.6m
  and larger
• NGIS link margins will be calculated based on SRO
  dish size

9
Technology

• Real Time
• Installed base (Digital Vision IRDs)
• Non-Real-Time file transfer (NRT)
• DVB-S2

10
Non-Real-Time Transition

• Begin deployment in 2005
• Edge Systems
• Terrestrial network (VPN)
• File distribution application
• Subscription (NPS)
• Library Retrieval
• Peer to Peer

11
Bandwidth Acquisition

• NGIS is planned as a 10 year build
• Up to 4 Ku transponders
• 50 states plus P.R. and U.S.V.I.
• Terrestrial bandwidth for VPN
• DVDs to Guam and Am. Samoa

12
Station Equipment

• Station equipment (RT)
• IRDs
• Station equipment (NRT)
• IP Satellite Receivers
• WAN
• Edge Server
• SDI output ports
• HD-SDI input port
• 2 TB of local storage

13
Operational Interface

• Master Control
• Automation
• Archive
• Analog or digital

14
Programming Interface (Metadata)

• Traffic (PODSv4)
• Programming
• Asset Management
• Purge Schedules (Record Schedules)

15
PODSv4 Highlights

• Data stream ready for both RT and NRT operations
• Daily updated files available
• Library/Archive files available for data
  synchronization
• Frame accurate time code
• XML format compatible with Myers Protrack and
  Scouts ProgramPlus
• Release in mid March 05 coincides with PBS
  BroadView Implementation

16
NGIS Business Continuity Plans

• Disaster Recovery
• Service restoration
• Long-term archiving
• PBS will re-evaluate sites
• Location
• Climate/natural disasters
• Connectivity

17
Peer-to-Peer

• Exchange of program files among member stations
  and producers
• Three elements
• File standard (MXF)
• Bandwidth
• Small amount - PBS provided
• Stations can provide much more
• Common tools
• COTS ftp, Gnutella, Bittorrent
• Custom integrating PBS metadata
• Currently being evaluated

18
MXF What?

• Industry-wide initiative
• Material Exchange Format
• SMPTE Standard
• Provides standard wrapper around essence for
  interoperation
• Server vendors now supporting MXF
• IMX and DV essence today
• Long-GOP MPEG-2 essence in 05

19
MXF-AS/PBS

• MXF Application Specification for PBS
  distribution
• It isnt enough to just say MXF
• Long-GOP 420 MPEG-2
• Standard Audio VBI features
• Metadata scheme (PB Core?)
• Working with key PTV vendors
• Avid, Leitch, Omneon, Pinnacle, SeaChange, Sony,
  Grass Valley
• Patterned after MXF-AS/CNN

20
The Scale of NGIS NRT

• 10,000 Hours/year (APT, NETA, PBS)
• 28 hours of unique content/day
• Live and near-live 8 hours/day (average)
• NRT 20 hours/day
• NRT Distribution
• 4xRT 5 hours of transponder utilization

21
Satellite vs. Terrestrial Costs
22
What can you do?
