  1. Motivations for the All-IT Media Facility Al Kovalick Media Systems Consulting Feb 20, 2014

  2. Migration Patterns Traditional AV Cloud-grade private/public Traditional IT

  3. Six Undeniable Technical Trends

  4. Moore’s Observation 4TB Transistor on Chip Density Growth 2x/2Yr ❶ Wikipedia ❷ Disc Storage Capacity Growth ~60%/Yr

  5. ❹ • Everything is virtualized • On-demand resources • Scale, agility • Persistent storage • Speed of deployment • Proven ROI in the enterprise ❸ Metcalf’s Law - Connectivity (160K)

  6. ❺ 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 Virtualizationhas a share too.

  7. 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) ❻

  8. Leveraging the Trends

  9. Facility Core and Edge Views Core IT Infrastructure Edge becomes smaller and more IT friendly over time. Hybrid AV+IT for many years. S/M/L/XL, fixed, mobile Core Facility IT Cloud resources Edge; AV consoles, capture/display devices, I/O legacy, SDI

  10. But, is Ethernet/IP up to the streaming challenge?

  11. Packetized AV Streaming ? • Lossless QoS, low delay • Mammoth rates (HD, UHD, 4K, 8K) • Point to multipoint • Sync’d • Frame switched …?

  12. Three Methods to Packet Stitch AV Streams • Source Timed control method • Not as SDI switching. Frame accurate effect • Switched Timed control method • As SDI switching, stream switch during VBI. Frame accurate • Destination Timed control method • Not as SDI switching. Destination assists in “splicing” two streams. Frame accurate effect.

  13. A→B Video at C To all nodes A→B A B A→B A→B A X C B Destination Timed; Receive A Receive A + B (2x) Switch A to B Receive B • Switch Timed; • VBI line switch (~SDI) • Controller or switch timed • SDN methods Source Timed; - UDP Port ID - Multicast Groups - Other ways

  14. Codecs Reduce the 4K/8K Burden Form SDIRate w/codec UHD/60 12G 2G 8K/60 48G 8G 10G Video Codec • Visually lossless (6:1) • Very low latency; few lines • “cheap and simple” • Frame switchable Raw Video 10b 4:2:2 UHD/4K/8K Ethernet 1G Form SDIRate w/codec HD/60 3G .5G CHEAP!

  15. 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)

  16. 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.
