Exploration of Video Over IP: Niche player or a replacement for
SDI?
IP Revolution Reaches Playout
Sara Kudrle
Introduction • What is IP? • What are benefits? • Successful transitions? • Challenges for other areas
• IP – Internet Protocol • IP = 1 layer of the OSI model • OSI - Open Systems Interconnection • IP identifies the network address of
the device
IP = Packet Based Technology
What is IP?
IP is not really new in the context of a TV station
• IP networking is widely used in any enterprise today
• Broadcasters have been exchanging files over IP for many years, either between facilities or within the same facility (NLEs, servers etc…)
What are the benefits?
Popularity and lower cost of IP
Technical advantages: data capacity of Ethernet, easier implementation of
redundancy etc…
Availability of trained staff
Other benefits of using an IP infrastructure • Flexibility / routability: all sources are
wrapped up and compatible with all destinations
• Truly redundant architecture
• Uses generic IP switches that are already in use in many facilities
• Leverages availability of IP-based monitoring solutions

EXECUTIVE SUMMARY • Broadcasters today are looking for solutions to improve their Workflow
efficiencies; enabling their facilities to break away from proprietary or hardware-based systems which have become inefficient, outdated and expensive. Then there is also 4K …
• For Broadcasters, an IP based Ethernet infrastructure is becoming an increasingly popular replacement to the traditional SDI-based infrastructure. IP infrastructures permit video data to be transported over Ethernet networks rather than via SDI switches and cables, and offer numerous advantages to broadcasters.
• IP infrastructures are scalable, provide greater signal capacity, are more flexible and far less costly to build and maintain – but broadcasters need to be careful not to sacrifice any functionality they require in the change.
• This presentation highlights in detail how new, innovative and cost effective technologies used by world leading broadcasters remotely manage, monitor and adjust streams from satellites, camera feeds, playout devices and other sources with an IP based infrastructure.
GOAL
Lower Staff Costs • Simpler operations using ordinary IT eqipment • Higher reliability using IT fail-over scenarios • Staff cheaper and more easy available -> IT staff • Ability for remote and cloud operations
-> outsourcing operations and/or facilities • Much lower OPEX
GOAL
Lower Equipment Cost • Simpler operations using ordinary IT equipment • Signal transport via WAN / Internet • Smaller footprint installtion – less space, energy
and heat • Dynamically scalable operations • Lower Total Cost of Ownership (TCO)
GOAL
Remote Operations / Cloud Operations • Real-time remote IP-based signal monitoring • Notifications of incidents at the remote site • Remote intervention e.g. re-routing IP signals,
changing playlists, replacing / migrating resources etc.
• Automated failover / recovery
SOLUTION APPROACHES
ALL-IN-IP Approach • Build a completely IP-based broadcast facility • Replace SDI wherever possible with IP
HYBRID APPROACH • Replace SDI with IP only where necessary • Do a step-by-step migration towards IP

BENEFITS OF IP-BASED FACILITIES
1. Avoidance of recompression (if source is compressed) 2. Lower infrastructure cost 3. Highly and quickly scalable infrastructure 4. Higher density – much lower space requirements 5. Higher reliability 6. Easy to go lights-out / to do remotely manage 7. Pre-requisite for going virtual or cloud-based
WHAT’S WRONG WITH SDI?
Some of the Issues with SDI: • SDI is an artefact of the analog age – CVBS to SDI • One cable per signal – not scalable, expensive • Dumb half duplex serial interface – no return data • No ability to transmit compressed video
-> introducing recompression workflows • Limited metadata (VANC/VBI) • Not extensible, not future-proof • Timing / sync problems
SDI IS NOT FUTURE-PROOF
Lifecycle of Video Signal Types:
• CVBS (analog) coaxial – 40+ years
• SD (270M) SDI coaxial – 20+ years
• HD (1.5G) SDI coaxial – <10 years
• HD (3G) SDI coaxial/optical - <5 years
• 4k – (12G) SDI optical or 4x 3G? – never?
-> new router
-> new router
-> new router
???
SDI IS NOT NEEDED TO CONNECT CAMERAS
• Sony NXL-IP55 IP-based camera interconnect with <1 frame delay –> 4x HD via Gigabit Ethernet
• IP cameras are common in security environments
• 3G/LTE cameras • IP-based vision mixers are
coming this year • 4k links will be HDMI 2.0 and IP • SMPTE 2022-6 & AVB
SDI IS NOT MORE RELIABLE
• To have redundant signal paths with SDI is theoretically possible but most equipment only has no redundant interfaces so this means the entire equipment needs to be doubled.
• The price for redundant SDI signal paths doubles the amount of cables, routers and other equipment
• For most facilities the additional cost of total SDI redundancy is prohibitive
• Redundancy for IP-based signaling is comparatively cheaper and easy to implement.
SDI IS NOT MORE RELIABLE
• SDI is a “protected” point-to-point connection • IP connections are usually multicast but can also be unicast
which is point-to-point • IP networks segments can be “locked” off by creating VLANs • Software Defined Networks (SDN) offer a complete new level of
flexibility in terms of adhoc network configuration • IP can failover on packet level • IP connections can be actively multi-path • Equipment supporting IP usually has multiple Ethernet ports
SO WHY STILL USE SDI?
Common answers: • “it is the status quo” • “lowest common denominator” • “the boxes we need all have SDI” • “workflows without SDI are impossible!” • and so on …
