•We must start by recapping the obvious! •2 main drivers for switching to IP Infrastructure: ‒FlexibilitX •Reconfigurable & infrastructure not limited by resolution/formats •Operational functions easier to relocate and evolve over time •More efficient architectures (don’t simply think about replacing SDI) •Software on generic IT servers rather than vendor -badged systems •may have to accept some compromises to change workflow ‒Costs > Use of more COTS hardware/software •minimise custom development and branched code makes systems easier to support •Up -front cost may not be lower (overall lifecycle costs may be lower) •Move to software -as-a-service (SaaS) – pay only for what you use when you need it! 4 AIMS IP Showcase IBC 2019 Curated by Video Services Forum vsf.tv September 2019 Copyright 2019 - No part of this presentation my be reproduced or repurposed without permission of the authors: telecompro.tv / Q3 Media Ltd. 3 I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 © 2019 telecompro.tv & Q3 Media Training – no part of this presentation can be reproduced or repurposed without permission of th e authors telecom pro .tv IP Video Training and Consulting Tailored Technology Training Q3MediaTraining.co.uk COTS Confusion However: •Not all IP hardware is equal •Networking for broadcast media production is specialist •Good system architecture & workflow planning is essential 5 • Defined Costs • Standards based • Choice (interoperable) • Generic Features • Stable • Supported • Upgradable • Variable Costs • Vendor lock -in • Interfacing/Conversion • Custom Features • Higher risk of issues • Fixed function • Limited/Costly to evolve COTS: Commercial Off -The -Shelf Proprietary / Bespoke System I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 © 2019 telecompro.tv & Q3 Media Training – no part of this presentation can be reproduced or repurposed without permission of th e authors telecom pro .tv IP Video Training and Consulting Tailored Technology Training Q3MediaTraining.co.uk The Rise of Software 6 •Dedicated Hardware still strong in production or wherever real -time processing with low -latencies are important •Media processing with Software is growing in capability •Software enables new architectures that don’t have equivalents in SDI •Motivation for vendors is changing to create products which can be sold in scale •IP Media Standards need to work for both software & hardware AIMS IP Showcase IBC 2019 Curated by Video Services Forum vsf.tv September 2019 Copyright 2019 - No part of this presentation my be reproduced or repurposed without permission of the authors: telecompro.tv / Q3 Media Ltd. 4 I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 © 2019 telecompro.tv & Q3 Media Training – no part of this presentation can be reproduced or repurposed without permission of th e authors telecom pro .tv IP Video Training and Consulting Tailored Technology Training Q3MediaTraining.co.uk IP is all about Packets! 7 SDI Signal Routing •Dedicated wire per signal •Routed via crosspoint switching IP Signal Routing •Multiple signals per wire •Packet -level switching •Full -Duplex (bi -directional) I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 © 2019 telecompro.tv & Q3 Media Training – no part of this presentation can be reproduced or repurposed without permission of th e authors telecom pro .tv IP Video Training and Consulting Tailored Technology Training Q3MediaTraining.co.uk IP is all about Packets! 8 SDI is a dedicated link with constant data rate SD -SDI: 270Mb/s HD -SDI: 1.5Gb/s 3G -SDI: 3Gb/s Ethernet links can have higher data rate so more data can be carried in the same time 10GE: 10Gb/s 25GE: 25Gb/s 40GE = 4x10GE 100GE = 4x25GE Data is sent in packets.
