IP in Broadcast Production
IMPACT OF IP BROADCAST INFRASTRUCTURE
Felix Krückels, Director of Business Development
Broadcast changes dramatically
Content distribution has moved from
linear model to non-linear consumption
Delivery to one platform has changed
to delivery to many platforms
The growth in the amount of content and methods
of delivery has diluted the economics available in
local markets
More demand for content on more platforms
but less money to produce that content
Everything is becoming smart
Everything is becoming smart
IP technology has become standard
in the office and private life
IT industry is a strong driver behind
“smart”
Broadcast equipment has been trad
itionally expensive IT Industry

SDI does not scale, massive special cabling is used
Scalability Video Router: Challenge to scale?
512*512 512*512
512*512 512*512
Scaling with IP?
Router
Switch capacity: 1152 X 10GE in 11RU
Approx. 7,000 X 7,000 uncompressed HD Signals
Approx. 50,000 X 50,000 lightly compressed HD
signals
Approx. 1000 X 1000 UHD/4K Signals
SDI does not scale!
IP is not deterministic
IP is not deterministic. There is currently no network platform available that can guarantee
100% delivery of content and control data in a shared environment.
IT storage and network technology is designed to be shared environments and
therefore default to best effort as load increases.
Quality of service protocols still fail in video environments under certain load conditions.
The wrong device activated in the wrong network port can impact all traffic flows
in infrastructure.
Tools needed
Network control that manages addition of devices and data flows by checking and confirming th
eir network activity before allowing them to participate in the network
Network devices must be flow aware and provide bandwidth management and guarantee
Control systems must be fully redundant
Evolution from SDI to IP; orchestrate both with one system

Reliability
Broadcast orchestration needs to guarantee the same robustness and stability of the Video and Audio Flow which is known from SDI and MADI Routers!
Where is IP used in production today?
• OB Van for Stagebox Connectivity
• Commentary since 2014
• Remote Production
Remote Production, Worldcup Brazil
ZDF REMOTE PRODUCTION
PCR IBC Remote Studio
• IFBs in the studio are remotely mixed from the mixing console in the PCR.
• Direct access to all Signals of the remote Studio.
• 1 RU for 4 compressed Video Signals and 128 Audio Channels • 1 or 3 RU for AUDIO IO

Summary
• Market dynamics demand a new approach, and the benefits we get from IT are compelling
enough to undertake the challenges introduced with IP Routing.
• The four main drivers are:
1. The broadcast industry will benefit from the drivers behind IP technology. The relatively
small media industry can take advantage of the gains that are created from mega IT,
internet, smart phones and other industries.
2. Flexibility. Apply the same benefits that IP has provided in every day life to the broadcast in
dustry.
3. Capacity will continue to increase with Moore’s Law
4. The coexistence of various formats such as HD Video, 3G, 4K/UHD, 24/32bit Audio in
stereo, 5.1, 9.1 22.2 with any sample frequency and Control Data can be switched with the
same Router/Core Switch.
Summary
• IP Switch will be more and more main Backbone
• Technology is ready for Broadcast use today
• Tight integration in existing broadcast infrastructure will be
necessary
Thank you very much!
