Making Your SDI-IP Investment
Work for Your Business
By Dan Murray, Director of Product Marketing, at Telestream...

O

ne of the big technology trends in
the broadcast and media markets
today is the transition from SDI to IPbased production and distribution
workflows. While the advantages of IP
are many, there needs to be a clear ROI
before organisations can see the clear
pathway to making this transition. One
of the key enablers of this evolution is
Telestream.
This summer saw Telestream
announce major new functionality
and software-based feature sets for
its PRISM waveform monitor. The
company has developed its marketleading PRISM Waveform Monitor
into a single next-generation solution
that is equally well suited to SDI and
IP workflow applications. With this
major new version, PRISM can be
optioned for all the traditional SDI
waveform monitoring tools required in
operations, compliance, quality control
and post production workflows up to
8K resolution. Simultaneously, the
same product offers a comprehensive
suite of IP-based Waveform Monitoring
tools up to 4K resolution on 25G
Ethernet. PRISM includes enhanced
High Dynamic Range (HDR) and Wide
Colour Gamut (WCG) reports and tools
to increase efficiency in both SDI and
IP environments.
Initially we launched PRISM to
support early adopters of SDI over
IP technologies and deployments.
We found people mostly using wireshark, an off-line tool, and wanted
to give people a real-time view they
were accustomed to in SDI. Although
we knew that the IP transition would
be difficult, we wanted to be part
of the first systems and among the
group of leading-edge suppliers who
were implementing and learning. All
along we knew that we would need to
provide both IP and SDI connectivity
because it became clear early on that
SDI would need to exist for a long
time. The approach to evolve as the
market evolved... which meant that
most of the capability would need
to be defined by software. Although
more expensive and time consuming to
develop, we felt strongly that given the
uncertainty about how things would
unfold this was the best way to support

our customers. Early on we sold a few
units to POCs and manufacturers, but
this last year the IP portion of our
portfolio outsold the SDI portion and
continues to grow.
Developed with IP in mind
If you go back 20 years, there
was SD-SDI in PAL and NTSC and
that was it in terms of the formats.
Later this evolved into HD-SDI and
we had to contend with progressive
and interlaced and film-style frame
rates Then you move to 4K and you
introduce dual-link, quad-link and
single link formats in quadrature and
interleave. Now, you take all this and
you map it into the different flavours
of IP: ASPEN, NDI, ST2022-6, and
ST2110-20/30/40 and so on. Any
one format and any one standard
is straightforward, but the overall

complexity is enormous. One overriding theme, as we mentioned above
was that even though customers were
transitioning to IP, all of the jobs they
were doing in SDI would remain the
same: establishing timing, confirming
ancillary data, decoding Dolby audio,
measuring guardbands, looking at
gamut violations, etc. Consequently,
at every step we need to build
capability that enables these jobs to be
performed in both IP and SDI for all of
the formats. Again, an expensive and
time-consuming job but one we were
convinced needed to be done. There
would be no IP-only installations,
nor would everyone move to IP
unilaterally. We had to support both.
At Telestream, we built our system
from the ground up to be both IP and

SDI. When you buy PRISM there is
no additional charge or option card
for IP or SDI - it's part of the base
configuration. What we felt was the
wrong way to go, long-term, was to
simply build an IP converter on the
front end of a traditional waveform
monitor. While there's an easy
transition from ST2022-6 (which is an
IP encapsulation of SDI) we knew that
long term these two formats would
diverge and we needed to be dealing
natively with each of them. We didn't
want to figure out how to convert 32
separate audio flows (a real case) and
try to be jamming this through an SDIbased system that couldn't deal with
that many audio tracks. It has been a
big investment, but one we now look
at and feel this sets us up well for the
future. In this regard, I think PRISM is
unique.

Telestream PRISM SDI-IP

New Standards Monitoring
As IP networks grow, scalable
visibility and test become important
for network operation. Another
strategic milestone was passed this
summer with the introduction of
our Inspect 2110 Quality Assurance
(QA) probe. Designed to seamlessly
integrate alongside the PRISM
waveform monitor, Inspect 2110
monitors ST 2110 video streams
including PTP synchronisation at
broadcast production facilities and
contribution streams to TV service
providers.
Inspect 2110 enables automated
monitoring of ST 2110 video
networking, providing operations
teams with visibility and alert

by exception of their entire
video networks. It provides high
performance
software-based
monitoring up to 100Gbps of ST 2110
video, audio, and data across dual
100GE interfaces. SDP file comparison
confirm that video streams are
working as expected at the same time
as providing automated confirmation
and comparison of redundant streams.
The PRISM SDI/IP waveform monitor
is the market leading deployment of
ST 2110 and PTP deep analysis, trusted
by broadcasters, operators and most
vendors. Now, Inspect 2110 provides
automated direct click connectivity
to PRISM for deep analysis, providing
an industry leading combination of
ST 2110 monitoring and deep analysis
solution.
Users
report
that
PTP
synchronisation is a top challenge for
ST 2110 migration. Now, Inspect 2110
monitors PTP behaviour and status
while the PRISM waveform monitor
enables deep analysis. Throughout
its development, Telestream has
future-proofed Inspect 2110's design
at every stage. It features an APIfirst container-based microservice
architecture for automation, which is
ready for cloud-centric architectures.
As ST 2110 networks grow,
operations staff lose visibility and
require scalable automated monitoring
to provide visibility and alert on
exceptions. With Inspect 2110 and
PRISM operating in combination
we have developed the first ST 2110
Monitoring & Waveform Monitor single
vendor solution.
Using the development resources
of Telestream's IQ and Tek Video
business units, we have developed
Inspect 2110 to provide scalable
monitoring for simplified management
of growing video networks. It provides
single click automated connection of
any ST 2110 video stream to PRISM for
deep analysis, offering a single vendor
monitoring & deep analysis solution.
We are taking orders for Inspect
2110 globally and will start shipments
this Fall. For more information, and
