Motivations for the All-IT Media Facility Al Kovalick Media Systems Consulting Feb 20, 2014 Migration Patterns Traditional AV Cloud-grade Traditional IT private/public Six Undeniable Technical Trends Moore’s Observation 4TB Transistor on Chip Density Growth 2x/2Yr ❶ Wikipedia ❷ Disc Storage Capacity Growth ~60%/Yr ❹ • • • • • • ❸ Metcalf’s Law - Connectivity (160K) Everything is virtualized On-demand resources Scale, agility Persistent storage Speed of deployment Proven ROI in the enterprise SaaS, Web Apps ❺ “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) ❻ Leveraging the Trends Facility Core and Edge Views Core IT Infrastructure Core Facility IT Edge becomes smaller and more IT friendly over time. Hybrid AV+IT for many years. Cloud resources 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. A→B A→B Video at C To all nodes A A→B B A→B A X B Source Timed; - UDP Port ID - Multicast Groups - Other ways C Destination Timed; Switch Timed; - VBI line switch (~SDI) - Controller or switch timed - SDN methods 1. 2. 3. 4.

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.
