Stream Circle Is
My IBC 'Must See'
"On all of my trips to the IBC since the early '90s, I have always prepared a last
minute list of must-sees. This year, I simply cannot omit the revolutionary, Game
Changer award-winning Stream Circle solution," writes Martin Junek from Provys.

T

wenty
years
ago,
digital
production workflows triggered a
transition from a precise synchronised
analogue signal to a digital domain
i.e. data and files. Around ten years
ago, most countries stopped analogue
broadcasting, sold some bandwidth
to telcos for better data services, and
television has not been real-time since
then.
Digital transmission allows more
channels, but it is still extremely
expensive if it is not watched by many
thousands of people. Broadcasters
need to deliver more channels for
less money, but DVB has a limited

bandwidth and is expensive. At the
same time, IP delivery is becoming
cheaper and allows the launch
of specialised channels targeting
smaller audience groups. At the same
time, most people still want to be
"entertained" and so require linear
type programming.
These are exactly the needs that
Stream Circle fulfils: a cost-effective
TV type of entertainment production,
extremely cheap for traditional
broadcasters and quite affordable
for newcomers as well. Bearing in
mind that today's digital transmission
is no longer real-time, investment
in complex equipment, in order to
achieve a real-time digital signal, isn't
really worth it. In broadcasting, this is
not evolution; it is a revolution.

Stream Circle claims that, in addition
to linear programme scheduling
and delivery through IP networks, it
also facilitates complete automation
workflows for playout, which include
live video, full-featured graphics
insertion, closed captioning, crawlers,
and multiple audio channels. All of
this is a cloud-based linear TV service
requiring no CAPEX. Technically,
the streamed channels can reach
their viewers in a number of ways -
standard delivery through available
CDNs, through a Smart TV application
or an HbbTV application.
As Josef Vasica, CEO of Stream Circle
points out: "If we turn our attention
to the workflows of the traditional
broadcaster, we may assume that
they run some standard traffic system,

specialists CLS Audiovisuais, who
started using Optocore devices soon
after setting out in 2004, have now
embraced technical partner, BroaMan's
versatile Mux22.
The company has purchased a
system from the company's territorial

CLS Wimbledon Drive Rack

dealer Garrett Audiovisuais, installing
the 1RU multi-format transmission
device in one of their full HD camera
and control OB's in time for the recent
Wimbledon Tennis Fortnight.
Mux22 series is ideal for OB truck
applications. In one rack space it
provides every type of signal which is

required between the truck and the
remote stagebox.
The device offers every signal
needed in 1RU, combining 3G/HD/SDSDI I/O with Optocore and SANE digital
audio networks - and can transport
video, as well as audio and data, on
a single duplex fibre. In this instance
CLS has constructed a point-to-point
system with 12-in/4-out at one end and
4-in/12-out at the other. Configured
with a master control room and two
galleries for beIN Sports (MENA)
in France, CLS' OB truck includes a
studio, two commentary positions for
each plus reporters and ENG crews.
For the past two years Wimbledon
has formed an essential part of their
busy international sports schedule and
the Mux22 enables them to uplink the
signal, elegantly and economically, to
the studios in Paris.

services. Certainly, they would prefer
not to build a new master control
for each internet TV channel. This is
precisely the open door for Stream
Circle to offer its internet linear
automation service purchased on a
monthly basis to maximise cashflow
efficiency. The only necessary step is
to integrate the traffic system and the
ad-sales platform with Stream Circle

the content metadata, schedules, adcampaign content and provide on-line

important part in their decision. "We
have been working with Optocore
since 2006, so we know their products
well," said CLS owner, André Senos.
In fact four X6R-FX AD-DA of their
network converters are incorporated
into the OB van signal chain.
"We had been seeking a solution and
once we had seen the product at IBC in
Amsterdam, and Garrett had arranged
a demo we knew this was the right
technical solution."
During Wimbledon Tennis Fortnight,
the OB van received 14 signal feeds
from host broadcaster, the BBC over
a distance of 250 metres from the
transmission centre; they were one
of 2,500 broadcasters providing an
HD experience from all nine courts to
viewers in more than 100 countries.
"Mux22 enabled us to take a lot of
HD signals and transmit down a single
fibre," concluded André. "Everything
worked extremely well."
As for Garrett Audiovisuais, set up
in 1978 they have been working with
Optocore virtually since its inception,
and with their impressive portfolio
of audio, lighting and video brands
are geared up to meet the ever more
demanding AV requirements from
customers in the so-called PALOP
countries.
