FACILITY NETWORK DESIGN TO
HANDLE ALL THAT INCOMING
DIGITAL MATERIAL
Rick Stora
Director of Broadcast Operations
Sundance Digital
TWO DISTINCT NETWORKS:
A Video Network
And
An Operations Network
THE VIDEO NETWORK:
•Digital
Satellite Receivers
•Broadband IP
•Transcode devices
•Server Interconnections
Goal: Move large quantities of data around at Real Time or F.T.R.T speeds
Physical connections: Fiber, Fibre, GigE
THE OPERATIONS NETWORK:
•Traffic
•Automation
(On Air, Prep, Recording & Digital Ingest)
•Streaming
•Machine
Control
Goal: Support database communication for metadata sharing and consolidation
Support deterministic control of broadcast devices
INTERNETWORK COMMUNICATIONS:
•Essence
Connections
•Metadata Connections
•Control Connections
“I.T. DOES TV”
Essence
A recently coined phrase to
depict actual media:
Film

EVENT: Schedule Change
1) Traffic system requests a current
copy of the playlist
2) Automation returns the list in
XML format
The Traffic Office
determines that a
schedule change to
the running list is
required.
3) Traffic Operator makes the
adjustment
4) Just before submission, Traffic
makes a second request for the
list and checks to see if the
changes are still valid
Traffic
Automation
5) If so, the changes are passed to
Automation
6) Automation inserts the changes
to the list and confirms back to
Traffic

REAL SYSTEM DESIGN
You wouldn’t ask an Electrician to design your video networks.
I advise that you all consider utilizing the services of a
professional I.T. design engineer as you embark on your I.T.
build outs.
There is plenty for you to contribute to the process as most I.T.
designers have never had to wrestle with the performance
loads and requirements that we are asking our systems to do.
Thank You
