Telestream's Inspect2110 carefully
monitors IP stransport streams

The Artel SMART
Media Delivery Platform providing compression where needed

purpose-built hardware. We think
early adopters and fast followers
migrating their workflows to cloud
will see a greater return on their
investments. "
At Telestream, Dan Murray circles
the conversation back to the transition
that is still underway from SDI to video
over IP. " Broadcast video engineers
are typically SDI experts, " he says.
" The transition to video production
over IP transport represents new
challenges for production teams,
needing solutions that help them
transition video to IP network design,
provide visibility and diagnostics. SDI
included video, audio and metadata
in a point to point cable. IP Video

transport has separate video, audio(s)
and metadata that needs to streamed
together across the IP transport
network. "
He sees PTP synchronization as
critical for video over IP transport,
not only ensuring video and audio are
synchronized, but that IP transport
has consistent performance including
latency, jitter and consistent nonbursty traffic. Which is where the
Telestream Inspect 2110 comes in.
" It provides broadcast operations
teams the visibility needed to
operate video over IP transport

involved in the solution to re-create
deployment environments, " states
Rafael Fonseca, Artel's VP of Product
Management.
" We are seeing two pain points in our
deployments, " he elaborates. " The first
is ensuring interoperability between
vendors at the IT network level, where
we find deviations in implementation
of protocols and standards. The
second is a need for greater awareness
of
bandwidth
restrictions
and
availability in the core network so that
implementers can leverage the proper
technology, e.g. compression methods,
to address these limitations.

" The transition to video

Dan Murray, Telestream

also investing heavily in the
SMPTE ST 2110 video-over-IP
format - which is positioned to replace
SDI as an uncompressed transport
medium, " he says, as well as paying
close attention to the industry's move
toward compressed IP technology with
ST 2110-22. "
The positivity of the 2110 message
is echoed by the company's Marwan
Al-Habbal, but he points out that it's
not without its issues, which is why the
company has launched the VERO ST
2110 signal generator and diagnostic
appliance to deal with them. " A rogue
ST 2110 device may not deliver as
expected, or worse, could adversely
affect other functioning devices and
lead to unpredictable general failure, "
he says. " Due to a number of variables,
a simple pass-fail test may not be
sufficient to make informed decisions
on choice of equipment. For example,
network packet timing is very different
when several transmitters are sending
to one receiver compared to a single

Close to the EDGE - Matrox's EDGE
encoder and decoder pair

at scale, to ensure video/audio/
metadata are correct, synchronized
and operating as expected, " he
says. " Video over IP transport at
large scale requires automation, to
simplify implementation and network
management. Inspect 2110 provides
automated video over IP transport
monitoring, to help operations
implement ST 2110 with confidence. "
Artel's efforts when it comes to
IP are split into two. On the product
side it is offering a software-defined
module, the Artel SMART Media
Delivery Platform, that provides
compression for those applications
where bandwidth restrictions exist.
Then at the service level the company
provides support, and IP, IT, and PTP
networking expertise to guarantee
proper operation of the solution at
hand.
" To avoid interoperability issues,
we also collaborate with the vendors

At Matrox, Daniel Maloney, Technical
Marketing Manager, talks of the
challenges of using public networks
for IP transport and the difficulties
of balancing quality, latency, and
reliability together. " If you add multistream synchronicity as a requirement
to the mix, there will be plenty of
potential pitfalls, " he says.
Hence the company's Matrox
Monarch EDGE encoder and decoder
pair, which combines high-quality,
high-density 4:2:2 10-bit H.264
encoding with low-latency glass-toglass transport of native interlaced
or progressive content. The decoder
also provides multi-channel SDI
output alignment based on encoder
timestamps and genlock input to a
house sync. Reliability is provided via
the SRT streaming protocol.
As to the future: " Matrox Video is

transmitter sending to a receiver. The
timing of a sender is also different if
it sends a single ST 2110 flow versus
several flows. A receiver might
work well with a narrow gapped
transmitter - like an SDI-to-IP gateway
- but not work well with a wide linear
transmitter. "
