Facility Core and Edge Views Core Facility IT Edge; AV consoles, capture/display devices, I/O legacy, SDI Edge becomes smaller and more IT friendly over time. Hybrid AV+IT for many years. S/M/L/XL, fixed, mobile Cloud resources Core IT Infrastructure
But, is Ethernet/IP up to the streaming challenge?
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.
A B X C Source Timed ; - UDP Port ID - Multicast Groups - Other ways Switch Timed; -VBI line switch (~SDI) -Controller or switch timed -SDN methods A →B To all nodes Destination Timed; 1.Receive A 2.Receive A + B (2x) 3.Switch A to B 4.Receive B A B A →B Video at C
Codecs Reduce the 4K/8K Burden Visually lossless (6:1) Very low latency; few lines “cheap and simple” Frame switchable Raw Video 10b 4:2:2 UHD/4K/8K Video Codec Ethernet 10G 1G Form SDI Rate w/codec UHD/60 12G 2G 8K/60 48G 8G Form SDI Rate w/codec HD/60 3G.5G CHEAP!
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.
