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 $21B in 2013 (IDC, 2013)

Leveraging the Trends

Facility Core and Edge Views
Core Facility IT
Edge; AV consoles, capture/display devices, I/O legacy, SDI
Edge becomes smaller and more IT friendlyover time.
Hybrid AV+ITfor many years.
S/M/L/XL, fixed, mobile
Cloudresources
Core IT Infrastructure

But, is Ethernet/IP up to the streaming challenge?
![Page 11: Motivations for the All-IT Media Facility Al Kovalick Media Systems Consulting Feb 20, 2014](https://reader030.vdocuments.site/reader030/viewer/2022032516/56649c785503460f9492dc38/html5/thumbnails/11.jpg)
Lossless QoS, low delay Mammoth rates (HD, UHD, 4K, 8K) Point to multipoint Sync’d Frame switched …?
Packetized AV Streaming ?

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.

Codecs Reduce the 4K/8K Burden
• Visually lossless (6:1)• Very low latency; few lines• “cheap and simple”• Frame switchable

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.
