SES, Inverto,
Abilis and MaxLinear
deliver satellite TV
home distribution
with industry’s
first IP-LNB
SES, Inverto,
Abilis and MaxLinear
Inc. announced
that they have been
jointly designing an
essential component
for cost-effective
IP distribution of
satellite television
to the home – the
first low-noise
block down-converter
(LNB) that will
incorporate
eight-channel
satellite-to-IP
bridging technology.
The IP-LNB is a
prototype device that
will deliver eight
concurrent channels from
any of the transponders
of a satellite orbital
position. These channels
may be forwarded via IP
unicast or multicast to
fixed and portable
devices. Satellite
signals will be
distributed via
Ethernet, power-line
communications (PLC) or
a Wi-Fi local area
network (LAN). The
technology can be used
for free-to-air (FTA) or
pay TV applications.
“The IP-LNB will give
satellite television
providers and consumers
new options for
distributing unmatched
quality satellite
television to multiple
TVs, computers and
tablets over IP at the
lowest cost,” said
Thomas Wrede, Vice
President of SES
Reception Systems. “When
we committed ourselves
to making SAT>IP an open
standard, we envisioned
this type of innovation.
It is exciting to see it
now come to fruition.”
The LNB is a crucial
element of a satellite
system, receiving
signals collected by the
satellite dish,
amplifying and
converting them to
intermediate frequencies
to be carried to the
set-top box (STB).
By locating the
satellite reception and
the IP bridging
functions in the antenna
the IP-LNB will enable
satellite content
distribution to the home
over a single Ethernet
cable. The IP-LNB may be
powered over that same
cable through Power over
Ethernet (PoE)
technology, greatly
reducing the overall
system cost and power
consumption.
This new technology
enables the satellite
signal to be sampled
digitally directly at
the antenna, making the
satellite spectrum data
and other link-quality
metrics accessible over
the LAN. These
advancements greatly
simplify the dish
installation and enable
remote monitoring from
the LAN.
Designing such a
novel LNB requires
significant advances in
satellite chipset and
real-time IP streaming
software technology in
order to meet the unique
system requirements on
the size, power
consumption, long-term
reliability and price
point required for a
commercially viable
outdoor unit (ODU).
