Newtec Survey Reveals DVB Switch
S

40

atellite specialist Newtec
has carried out an extensive
industry survey to gauge the
temperature of the satellite sector
as DVB makes plans to roll-out
extensions to the existing DVB-S2
standard at the end of the summer.
The results come as a number
of new standards are entering the
market for quality (UHDTV 4K/8K),
compression (HEVC) and satellite
transmission (DVB-S2 Extensions).
Newtec carried out a survey, and
based on over 700 responses from
more than 400 satellite companies, it
is fair to say the results represent the
living pulse of the satellite industry.
One of the key ﬁndings of the survey
is that more than half of the industry
will switch to the new standards
within one year of release.
“The satellite world has changed a
lot since DVB-S2 was ﬁrst published
in 2005. Higher speeds, more
efﬁcient satellite communication
technology and wider transponders
are required to support the exchange
of large and increasing volumes of
data, video and voice over satellite,”
said Dirk Breynaert, Founder and
CTO of Newtec.
How do the S2 Extensions Work?
Just around the corner now,

the update to DVB-S2 is likely to
transform the sector. Newtec, along
with DVB, has been developing a
number of candidate technologies.
These extensions have the potential
for up to 37% improvements on
top of the current standards
and this jumps up to 64% or
more with 72MHz wideband
transponders. The new standard
has seven main improvements
compared with DVB-S2:

Lower Roll-Offs (RO): Reducing
RO to 5%, 10% and 15% results in
a direct gain in bandwidth;
Advanced Filtering for Improved
Carrier Spacing: The second
innovation deals with noise
levels (side lobes) on both sides
of the carrier;
Supporting Different Network
Configurations: S2 Extensions
can easily co-exist with adjacent
carriers from other operators within

the same transponder;
Increased Granularity in MODCOD:
The number of MODCODs has
grown from 28 in DVB-S2 up to
87 in the S2 Extensions bringing
efﬁciency as close to the theoretical
Shannon limit as possible;
Higher Modulation Schemes Up
To 64APSK: When combining the
increased granularity (MODCODs
and FECs) and 64 APSK (higher order
modulation and coding) immediate
efﬁciency gains up to 37% can be
achieved compared to DVB-S2;
Better MODCOD Implementation:
Compared to DVB-S2 the MODCODs
themselves have been improved
in S2 Extensions to achieve even
better efﬁciencies. S2 Extensions
also have two different classes for
linear and non-linear MODCODs;
Wideband Implementation: The S2
Extensions support technology for
typical wideband transponders that
become/are available today hosting
high-speed data links.
S2 Extensions At IBC2013
At IBC2013, on Saturday afternoon
at 3pm, Newtec is holding a panel
discussion with industry leaders to
discuss the impact of S2 extensions
to their business, their operations,
and the industry in general.

Gepco Debuts Hybrid Fibre Cables
E

xhibiting the latest Gepco Brand
innovations in hybrid fibre
cabling and accessories, General
Cable will unveil its breakthrough
7.2 mm Hybrid Fibre Cable and new
SMPTE Hybrid Fibre Cable Tester at
IBC2013, running September 13-17.
A leap forward in hybrid fibre
cabling for mobile and permanent
install SMPTE applications, the
new Gepco Brand HDC720HD 7.2
mm Hybrid Fibre Cable is the ﬁrst
piece of a patent-pending hybrid
ﬁbre system that solves the most

common durability issues associated
with SMPTE camera cables in a
smaller, lightweight design.
The revolutionary construction
of the HDC720HD starts with
eliminating the typical heavy steel
strength member which often
contributes to premature cable
failure due to different expansion and
contraction rates of the individual
elements within the SMPTE hybrid
fibre cable during temperature
extremes. In the HDC720HD, the
steel is replaced by a strength
member that has the same pull
strength of steel, but is lighter and
more flexible. Unlike steel, this
strength member expands and
contracts at the same rate as the
glass members. Using this new
strength member in place of steel
also means the cable has virtually
no memory making the cable easier
to pay off, lay ﬂat and wind back
up on the drum.
For further durability, the
HDC720HD utilises bend-insensitive
fibre elements with very low
attenuation and a bend radius of 0.2
mm–versus 2.0 mm for traditional

single-mode ﬁbre–in a breakout style
with additional Kevlar protection
around the individual fibres.
In the HDC720, the typical outer
braid is replaced with two 18 AWG
drain wires that allow the cable to
be more ﬂexible, lighter and smaller
in diameter. The master jacket of
HDC720HD is polyurethane which is
tougher than PVC for rugged outdoor
use, and its glossy ﬁnish reduces
the pickup of dirt and debris from
outside applications making it easier
to keep clean.
With a 31% smaller diameter
and a 40% weight savings over 9.2
mm cables, HDC720HD allows 300
meters of cable on a drum in the
same space and less weight than 200
meters of 9.2 mm cable occupies.
“The new HDC720HD cable ﬁxes
so many of the common issues with
SMPTE hybrid ﬁbre camera cables
with the added bonus of being smaller
and lightweight,” said Joe Zajac,
Sales and Applications Engineer for
Gepco Brand Products. “This makes
the HDC720HD extremely ideal for
use in portable applications and with
high-deﬁnition Steadicams.”

Also debuting at IBC, the Gepco
Brand SMPTE-304TS Hybrid
Fibre Cable Tester–ideal for use in
sports/events broadcasting, ﬁxed
and mobile facilities or wherever a
SMPTE HD camera cable is used.
The SMPTE-304TS tests both
electrical and optical circuits while
the intuitive display graphically
depicts which contact is defective
or pinned out incorrectly.
Compatible with all SMPTE 304
standard connectors, the SMPTE304TS has a portable, hand-held
design and provides over 40 hours of
continuous use without recharging,
while the diagnostic OLED backlit
display can be easily seen in
direct sunlight or at night. Each
SMPTE-304TS test set includes a
metering unit and optical source
unit with black aluminium frames,
a rechargeable NiMH battery with
charger, a USB to USB-mini charging
cable and a rugged ABS plastic
carrying case.
