Everything is virtualized
On-demand resources
Scale, agility
Persistent storage

Proven ROI in the enterprise
SaaS, Web Apps

“Software is dead” – Marc Benioff
Web Apps (SaaS or captive) are the future of the UI.
Any location, browser based, not installed; Gmail…
Desktop Virtualization has a share too.
Ethernet Celebrated its 40th anniversary in May of 2013
@2017 – 400 Gb/s Ethernet,
1Tb/s in 2024
~300 3G SDI links will
fit into one 1 Tb link
Switches/Routers

Edge becomes smaller
and more IT friendly
over time.
Hybrid AV+IT
for many years.

S/M/L/XL, fixed, mobile
Edge; AV consoles, capture/display devices, I/O legacy, SDI
But, is Ethernet/IP up to the streaming challenge?
Packetized AV Streaming ?

Lossless QoS, low delay
Mammoth rates (HD, UHD, 4K, 8K)
Point to multipoint
Sync’d
Frame switched …?
Three Methods to Packet Stitch AV Streams
1. Source Timed control method
• Not as SDI switching. Frame accurate effect
2. Switched Timed control method
• As SDI switching, stream switch during VBI. Frame accurate
3. Destination Timed control method
• Not as SDI switching. Destination assists in “splicing” two streams.
Frame accurate effect.

Progress from JTF-Networked Media
• JTF received 136 User Stories
• I want to losslessly stream AV using Ethernet…because…
• Distilled to ~16 Super User Stories
• Received technology from 27 companies/groups (RFT)
• Published Final Summary Report in December 2013 (117 pages)
Path to the Interoperable All-IT Facility
•
•
•
•
•
•
Demand “no proprietary, no closed solutions”; IT COTS
Standardize “SDI Payload over L2/L3” (2022-6)
Standardize frame accurate switch method(s)
Select audio over L2/L3 method (AES 67, AVB?)
Define best practices for network path QoS (loss, delay)
Leverage all things IT/Cloud; cloud first, ask why not.
