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

Broadcast

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!
